    Metagenomic Analysis of Low-Temperature Environments2017In: Psychrophiles: From Biodiversity to Biotechnology / [ed] Rosa Margesin, Cham: Springer, 2017, 389-421 p.Chapter in book (Refereed)
    Abstract [en]

    The Earth’s permanently cold biosphere is known to harbour abundant microbial biomass and represents a rich resource for the discovery of novel cold-adapted microorganisms, many of which form part of the ‘microbial dark matter’ which cannot be analysed using traditional culture-dependent approaches. The recent development of metagenomics and related multi-omics strategies has provided a means by which entire microbial communities can be studied directly, without the prerequisite of culturing. The advancement of the ‘omic’ methods is directly linked to recent progress in high-throughput sequencing, robust data processing capabilities and the application of cutting-edge analytical tools for high-throughput detection of biomolecules. The combined application of these tools and strategies has provided an unprecedented access to the structure and potential function of microbial communities in cold environments, providing increasingly comprehensive insights into the taxonomic richness and functional capacity of the indigenous microorganisms. Applications of ‘omic’ strategies have enhanced our understanding of psychrophilic adaptation mechanisms, revealing the versatility and adaptability of life in the ‘cryosphere’. In addition to the predicted roles of psychrophiles in biogeochemical cycling, recent multi-omic studies have further emphasised the importance of the ‘cryosphere’ in influencing global atmospheric conditions. Finally, metagenomic bioprospecting of cold environments has yielded a variety of novel bioactive molecules including novel ‘psychrozymes’, with a wide range of potential industrial and biotechnological applications. Here, we have provided an overview of recent developments in metagenomic technologies and their application in the study of the cold biosphere.

    Lecture attendance is a pivotal factor for improving prospective teachers’ academic performance in Teaching and Learning Mathematics2017In: Journal of Further and Higher Education, ISSN 0309-877X, E-ISSN 0013-1326, Vol. 41, no 1, 1-15 p.Article in journal (Refereed)
    Abstract [en]

    The value and importance of lectures in higher education is part of a modern education discourse worldwide. This study aims to estimate the importance of lectures for prospective teachers of kindergarten, preschool and early primary school. We analysed academic achievements of prospective teachers who had either mandatorily or voluntarily attended lectures in the subject of teaching and learning mathematics. Students’ examination grades in a maths course with mandatory or voluntary lecture attendance were analysed with a logistic model testing the association between lecture attendance requirement and grades. We show that mandatory lecture attendance (1) more than double the odds of students receiving a pass grade when their situated and tacit knowledge was examined and (2) quadrupled the odds of students achieving the highest grade (pass with distinction) when both their understanding of elementary mathematics and their situated and tacit knowledge of teaching and learning mathematics were examined. Our study provides evidence for a significant positive role of lecture attendance for students acquiring skills in Teaching and Learning Mathematics. While attending lectures students receive situated tacit knowledge of the subject which is otherwise difficult, if not impossible, for them to obtain in a different way. The observed improvement may have an additional positive effect in being a step towards overcoming a maths anxiety, which is otherwise relatively common among prospective teachers.

    Business as un-usual through dislocatory moments – change for sustainability and scope for subjectivity in classroom practice2017In: Environmental Education Research, ISSN 1350-4622, E-ISSN 1469-5871Article in journal (Refereed)
    Abstract [en]

    This paper makes a contribution to the debate that has been described as a tension between instrumental and emancipatory educational objectives in environment and sustainability education. The contribution involves a methodological approach (introd-) using the concept ‘dislocatory moments’, to identify and analyse moments in classroom practice that address educational objectives relating to ‘change for sustainability’ and ‘thinking and acting independently’. A case of business education, when ‘sustainable development’ is integrated in a series of lessons, is used to exemplify the approach involving analysis of the emergence and closure of a dislocatory moment and the change of logics that occur. The illustrative case shows how room for subjectivity and change can be intertwined in educational practice. It is suggested that the methodological approach could be used in empirical research of classroom practice to further knowledge about the kind of situations that contribute to ‘business as un-usual’ without compromising emancipatory education ideals.

    Deep sequencing analysis of tick-borne encephalitis virus from questing ticks at natural foci reveals similarities between quasispecies pools of the virus2017In: Journal of General Virology, ISSN 0022-1317, E-ISSN 1465-2099, Vol. 98, no 3, 413-421 p.Article in journal (Refereed)
    Abstract [en]

    Every year, tick-borne encephalitis virus (TBEV) causes severe central nervous system infection in 10 000 to 15 000 people in Europe and Asia. TBEV is maintained in the environment by an enzootic cycle that requires a tick vector and a vertebrate host, and the adaptation of TBEV to vertebrate and invertebrate environments is essential for TBEV persistence in nature. This adaptation is facilitated by the error-prone nature of the virus's RNA-dependent RNA polymerase, which generates genetically distinct virus variants called quasispecies. TBEV shows a focal geographical distribution pattern where each focus represents a TBEV hotspot. Here, we sequenced and characterized two TBEV genomes, JP-296 and JP-554, from questing Ixodes ricinus ticks at a TBEV focus in central Sweden. Phylogenetic analysis showed geographical clustering among the newly sequenced strains and three previously sequenced Scandinavian strains, Toro-2003, Saringe-2009 and Mandal-2009, which originated from the same ancestor. Among these five Scandinavian TBEV strains, only Mandal-2009 showed a large deletion within the 3' non-coding region (NCR), similar to the highly virulent TBEV strain Hypr. Deep sequencing of JP-296, JP-554 and Mandal-2009 revealed significantly high quasispecies diversity for JP-296 and JP-554, with intact 3' NCRs, compared to the low diversity in Mandal-2009, with a truncated 3' NCR. Single-nucleotide polymorphism analysis showed that 40% of the single-nucleotide polymorphisms were common between quasispecies populations of JP-296 and JP-554, indicating a putative mechanism for how TBEV persists and is maintained within its natural foci.

    Is adaptation reducing vulnerability or redistributing it?2017In: Wiley Interdisciplinary Reviews: Climate Change, ISSN 1757-7780, E-ISSN 1757-7799Article, review/survey (Refereed)
    Abstract [en]

    As globalization and other pressures intensify the economic, social and biophysical connections between people and places, it seems likely that adaptation responses intended to ameliorate the impacts of climate change might end up shifting risks and vulnerability between people and places. Building on earlier conceptual work in maladaptation and other literature, this article explores the extent to which concerns about vulnerability redistribution have influenced different realms of adaptation practice. The review leads us to conclude that the potential for adaptation to redistribute risk or vulnerability is being given only sparse—and typically superficial—attention by practitioners. Concerns about ‘maladaptation’, and occasionally vulnerability redistribution specifically, are mentioned on the margins but do not significantly influence the way adaptation choices are made or evaluated by policy makers, project planners or international funds. In research, the conceptual work on maladaptation is yet to translate into a significant body of empirical literature on the distributional impacts of real-world adaptation activities, which we argue calls into question our current knowledge base about adaptation. These gaps are troubling, because a process of cascading adaptation endeavors globally seems likely to eventually re-distribute risks or vulnerabilities to communities that are already marginalized and vulnerable. We conclude by discussing the implications that the potential for vulnerability redistribution might have for the governance of adaptation processes, and offer some reflections on how research might contribute to addressing gaps in knowledge and in practice.

    Production and characterization of a novel antifungal chitinase identified by functional screening of a suppressive-soil metagenome2017In: Microbial Cell Factories, ISSN 1475-2859, E-ISSN 1475-2859, Vol. 16, no 1, 16Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Through functional screening of a fosmid library, generated from a phytopathogen-suppressive soil metagenome, the novel antifungal chitinase-named Chi18H8 and belonging to family 18 glycosyl hydrolases-was previously discovered. The initial extremely low yield of Chi18H8 recombinant production and purification from Escherichia coli cells (21 μg/g cell) limited its characterization, thus preventing further investigation on its biotechnological potential.

    RESULTS: We report on how we succeeded in producing hundreds of milligrams of pure and biologically active Chi18H8 by developing and scaling up to a high-yielding, 30 L bioreactor process, based on a novel method of mild solubilization of E. coli inclusion bodies in lactic acid aqueous solution, coupled with a single step purification by hydrophobic interaction chromatography. Chi18H8 was characterized as a Ca(2+)-dependent mesophilic chitobiosidase, active on chitin substrates at acidic pHs and possessing interesting features, such as solvent tolerance, long-term stability in acidic environment and antifungal activity against the phytopathogens Fusarium graminearum and Rhizoctonia solani. Additionally, Chi18H8 was found to operate according to a non-processive endomode of action on a water-soluble chitin-like substrate.

    CONCLUSIONS: Expression screening of a metagenomic library may allow access to the functional diversity of uncultivable microbiota and to the discovery of novel enzymes useful for biotechnological applications. A persisting bottleneck, however, is the lack of methods for large scale production of metagenome-sourced enzymes from genes of unknown origin in the commonly used microbial hosts. To our knowledge, this is the first report on a novel metagenome-sourced enzyme produced in hundreds-of-milligram amount by recovering the protein in the biologically active form from recombinant E. coli inclusion bodies.

    Climate and environmental science denial: A review of the scientific literature published in 1990–20152017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 167, 229-241 p.Article, review/survey (Refereed)
    Abstract [en]

    Abstract Denial of scientific findings is neither a new nor an unexplored phenomenon. In the area of environmental science and policy though, the research on denial has not been systematically summarized and analyzed. This article reviews 161 scientific articles on environmental and climate science denial published in peer reviewed international journals in the last 25 years and aims to both identify research gaps and enable learning on the phenomenon. Such knowledge is needed for the increasingly important task to provide effective response to science denial, in order to put an end to its influence on environmental policy making. The review, which is based on articles found in the databases Web of Science, Scopus and Philosopher's Index, shows that denial by far is most studied in relation to climate change, with a focus on Anglo-American countries, where this form of denial is most common. Other environmental issues and other geographical areas have received much less scientific attention. While the actors behind climate science denial, their various motives and the characteristics of their operations have been thoroughly described, more comparative research between issues and countries is needed in order to draw reliable conclusions about the factors explaining the peculiarities of denial. This may in turn lay the ground for developing and actually testing the effectiveness and efficiency of strategies to counter environmental science denial. Irrespective of the ambitions of environmental goals, science-based policies are always preferable. The scientific community therefore needs to increase its efforts to dismantle false claims and to disclose the schemes of denialists.

    A social marketing perspective on road freight transportation of fresh fruits and vegetables: a Slovene case2017In: Ekonomska Istrazivanja, ISSN 1331-677X, E-ISSN 1848-9664, Vol. 30, no 1, 1132-1151 p.Article in journal (Refereed)
    Abstract [en]

    With the large increase in transportation over the last decades and the associated negative impacts upon the environment and society, a more sustainable use of transport is a crucial policy issue. This analysis focuses on road freight transport of selected produce (carrots, cabbage, apples and pears) with the aim to appraise the sustainability of road freight transport of these for the Slovene market. To this end, we take into account self-sufficiency, import and export features, transport needs, produce origin and prices differences between domestic and non-domestic produce. The method used for obtaining transported quantities, exported from and imported to the county, was material flow accounts (MFA). Then we undertook an analysis of sustainability of road transport of produce where we considered the country's transport needs. The study finds that road freight transport for selected produce is not sustainable. Recognising the normative dimensions of sustainability, the role of social marketing in this context is explored and suggestions on how to promote more sustainable transport solutions advanced.

    Abstract [sv]

    This article discusses the re-emergence and modernisation of traditional goat cheese production in Sweden, in particular in the northern county of Jämtland. The data have been gathered through fieldwork and interviews with goat farmers, authorities and others involved in the production of goat cheese. As early as the 1970s, a number of initiatives were taken to formalise the productive activities of this sector and to improve product quality. The most important project was the launch of the cooperative Jämtspira at the beginning of the 1980s. In contrast to other Swedish cooperatives, this organisation involved its members in developing a common trademark and a standardised product range, undertaking joint marketing efforts, and finding creative solutions to infrastructure problems. Jämtland was strengthened and modernised, largely owing to the active part played by regional authorities in this process. The national artisan centre Eldrimner, which became a hub for small-scale food production, is another important institution that has strengthened local knowledge and taught cheesemaking skills to new goat farmers from all over Sweden. Although many obstacles have been removed and the sector has found successful solutions to strategic issues relating to product development and marketing, there are still significant structural shortcomings that could reduce profitability and endanger the future development of the sector.

    Hästföretagande i storstadens närhet2017In: Genus och företagande / [ed] Madeleine Bonow, Paulina Rytkönen, Svenska sällskapet för antropologi och geografi , 2017, 159-182 p.Chapter in book (Other academic)
    Abstract [sv]

    För 150 år sedan bodde större delen av Sveriges befolkning på landsbygden och var sysselsatta i primärnäringarna, men under de senaste 120 åren har den svenska landsbygden genomgått en kraftfull strukturomvandling. idag är det endast 15% av Sveriges befolkning som bor utanför någon av Sveriges tätorter. Det vill säga 85% av befolkningen bor på 1,3 procent av landarealen och ytterst få är sysselsatta i de gröna näringarna. Den pågående omstruktureringen av lantbruket innebär att många av de mindre gårdarna läggs ned och blir fritidshus eller hästgårdar. Samtidigt som nötkreaturen minskar i antal ökar antalet hästar och Sverige har blivit ett av de hästtätaste länderna i Europa.

    Ungefär en halv miljon svenskar rider regelbundet och närmare en tredjedel av alla invånare i Sverige har på något sätt kontakt med hästar och de olika verksamheter som de ger upphov till. Denna ökning av sporthästar är särskilt märkbar i tätortsnära områden. I Stockholm och Uppsala län finns omkring 44 000 hästar och ca 78% av dessa finns i urbana eller tätortsnära områden. Hästarna har till viss del blivit landsbygdens räddning. hästar behöver mat, husrum och livsutrymme, vilket har skapat en välkommen extra inkomstkälla för lantbruket. Det är relativt vanligt att lantbrukare producerar och säljer hästfoder eller hyr ut stallplatser. Enligt lantbrukarnas Riksförbund, är hästnäringen den femte största inkomstkällan för jordbruket.  Hästen är även på andra sätt en viktig resurs i arbetet med att utveckla nya former för jordbruksföretagande och bidra till en levande landsbygd. Det ökande antalet hästar medför mer arbete för veterinärer, hovslagare och tränare/instruktörer. Dessutom växer det fram nya yrkesgrupper med specialinriktning mot hästar. Syftet med den här studien är att belysa kvinnliga hästföretagares syn på tätortsnära hästverksamheter och diskutera svårigheter och möjligheter för utvecklingen av hästnäringen med fokus på Stockholm- och Uppsalaområdet.

    Abstract [en]

    Research on gender and entrepreneurship, is a broad field of research developed in the intersection between theories about entrepreneurship and gender and feminist theory. Within this research field labor, family and the state are the key elements. The gender perspective is one of society's most important organizing principles and entrepreneurship is seen as important for promoting growth, creating jobs, etc. The study of gender and entrepreneurship in combination is therefore important to understand the forces that shape our history, our present and our future.

    This book is the result of a workshop organized by the Research Center Enter Forum, at Södertörn University in December 2015. The theme of the workshop was Policy, Entrepreneurship and Gender. Starting from a gender perspective, the papers presented analyzed how economic development and social processes has led to the emergence of new industries, and how technology and policy in cooperation may outcrowd women’s participation in certain industries. Additional topics are the impact of gender on firms ability to survive in the long term; How women entrepreneurs see women in business; How social entrepreneurship can be the catalyst for women's rights; And the the challenges and opportunities of female equine entrepreneurs in urban businesses encounter in their daily activities

    Urban Ponds for Breeding Medicinal Leeches (Hirudo medicinalis Linnaeus, 1758) in Sweden2017In: Meta: Medeltidsarkeologisk tidskrift, ISSN 0348-7903, 63-72 p.Article in journal (Refereed)
    Abstract [en]

    Leeches and their medicinal applications are well-studied in history. In Scandinavia the use of medicinal leeches for therapy is mentioned already by Olaus Magnus in his Historia de gentibus septentrionalibus (1555). Carl Linnaeus named the species Hirudo medicinalis. In the 1760s leeches became widely accepted as a medicament and the demand increased, not only in Sweden but all over Europe. By the 1830s around 50 million leeches were employed in hospitals every year causing a shortage of leeches all over Europe. However, the species is rare in Scandinavia. In Sweden medicinal leeches have been harvested in the southern part of the country. The local occurrence did not cover the large demand and imported leeches had to be used. In the nineteenth century, over-exploitation reduced many local populations and breeding medicinal leeches in ponds became a concern for authorities in many countries. Several farms for breeding leeches in ponds were also founded in rural and urban settings. We know very little about them, but toponyms serve to remind us of such ponds. This article aims to shed some light on the forgotten practice of breeding medicinal leeches in urban ponds in Sweden.

    Tourism as a tool for communicating complex environmental issues: Applying the ecosystem services framework to nature-based tourism activities across Iceland2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Throughout the twenty-first century, the lowering cost and increased availability of travel options has resulted in virtually uninterrupted economic growth of the international tourism sector. While financially beneficial, the increased movement of people has also been shown to have a negative impact on the environment, leading to the growth of a more environmentally-friendly approach to travel called nature-based tourism. One country at the forefront of the nature-based tourism movement is Iceland, and while the sector has grown significantly in the country over the past decade, the way in which information concerning environmental issues is communicated to tourists has not been widely researched. Being the case, the aim of this study was to examine the extent to which environmental issues are communicated to the general public through the use of the ecosystem services framework. Four popular nature-based tourism activities were selected for analysis; a whale watching tour, a horse riding tour, a boat tour of a glacial lagoon and a spa experience in a geothermal hot spring. A literature review concerning how the ecosystem services framework related to each of these tours was carried out and findings were compared to observatory data gathered through participation in said tourism activities. Results showed that while scientific publications could be found for each tour/ecosystem service combination, information concerning environmental issues was not widely communicated to participants in the nature-based tourism activities using the ecosystem services framework.

    Miljön som handelsvara: en diskursanalys över utsläppsrättssystem2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Växthusgasnivåerna i atmosfären har nått nivåer som påverkar klimatet på jorden. Det här ställer krav på politiska överenskommelser som effektivt kan verka för en minskning av växthusgaser i atmosfären. Kyotoprotokollet implementerades 1997 och innehåller lagbindande krav på medlemsländerna att minska sina växthusgasutsläpp och presenterar utsläppsrätter som styrmedel för att nå målen. Utsläppsrätter innebär att politiker sätter ett pris på rätten att släppa ut och låter verksamheter som förorenar handla med rätterna, vilket enligt nationalekonomisk marknadsteori är det mest effektiva sättet att gå tillväga. Detta kan däremot kritiseras av ekologiska ekonomer som motsätter sig prissättande av miljön.

    Diskursteori används för att studera vad som har normaliserats med införandet av utsläppsrättssystem och därför inte ifrågasätts. Analysen visade att två diskurser primärt råder i den utvalda empirin; ekonomisk liberalism och teknologisk tilltro. Fokus på vinst, tillväxt, kostnadseffektivitet samt teknikoptimism återkom i alla tre dokumenten och framställs som avgörande för att nå målen för utsläppsreduktion.

    Utsläppsrätter är ett ekonomiskt styrmedel vars styrka ligger i marknadsmekanismer, men ur ett hållbarhetsperspektiv finns problematik med prissättande av miljön; framförallt att det vilar på svag hållbarhet. Även marknadens otillräckliga förmåga att ta hänsyn till moraliska angelägenheter, prissättning av miljön och att ansvarsförskjutning mot företag placerar en större klyfta mellan människa och miljö kan tolkas som problematiskt.

    Toxic Textiles: Towards Responsibility in Complex Supply Chains2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The governance of the environmental and health problems that follow in the wake of globalised trade is one of the great contemporary challenges. One of these challenges is the management of chemical pollution and associated risks, and one sector facing this challenge is the textile industry, which has complex supply chains spread across continents. At the same time the role of actors on the playing field are changing and market actors are being called on to responsibly manage the issue of chemical risks and associated challenges. However, governance and control are often obstructed due to complexity and considerable knowledge uncertainty. This situation complicates responsibility-taking and makes it difficult to ascribe liabilities to specific actors, as it is not obvious who is responsible for what. This thesis is concerned with the process of how a group of market actors – private and public textile buyers – assume responsibility of chemical risks in their supply chains in a situation that is characterized by uncertainty and complexity. This thesis aims to contribute to an understanding of what happens when market actors are called on to manage the negative side effects of globalisation. The focus is on Swedish textile-buying private and public organisations. The thesis constructs an analytical model based on the key concepts responsible governance, responsibilisation, and responsible supply chain management (RSCM). The thesis explores the barriers, challenges and opportunities that exist for buyers seeking to assume RSCM and whether a process of responsibilisation can be observed in the textile sector. The thesis uses an exploratory approach and interviews, participatory observations and literature studies, as well as case studies to understand the process and to investigate barriers, challenges, opportunities. In summary, the thesis shows that a process of responsibilisation is ongoing on the organisational and sector levels. Further, it is shown that due to the complex structures of the chains, there are more barriers and challenges than opportunities for buyers striving for RSCM. However, it is argued that cooperation, stronger public and private policy, and a reflexive approach could be ways forward towards RSCM and increased responsibilisation in the textile sector.

    Testing the ecosystem service cascade framework and QUICKScan software tool in the context of land use planning in Glenlivet Estate Scotland2017In: International Journal of Biodiversity Science, Ecosystem Services & Management, ISSN 2151-3732, E-ISSN 2151-3740, Vol. 13, no 2, 12-25 p.Article in journal (Refereed)
    Abstract [en]

    The concept of ecosystem services has been extensively studied in recent decades. Most studies have focused on describing the specific aspects such as production, spatial extent, valuation of services and the trade-off between services. Few studies however assess the practitioners? views on the frameworks, models or tools developed. In this paper, we report on a multi-stakeholder workshop where two tools were tested (i) the ecosystem service cascade framework was tested as a means to frame the issues and (ii) a participatory-spatial modelling method, QUICKScan, was tested as an aid to support discussion over natural resource management and planning in a multi-use landscape. A focused group discussion was utilised to determine stakeholders? views of the cascade framework and pre- and post-workshop questionnaires quantified the stakeholders? views of the QUICKScan method. The stakeholders identified both positive and negative aspects of both tools. The diversity of views expressed were associated with (i) the past experience of the individual with the issues discussed, (ii) the technical aspects of the tools i.e. the ability with GIS and (iii) the level of new shared knowledge they reported acquiring on the day which was related to their initial knowledge of the issue and area studied.

    Jordbruksfåglarnas minskning i Stockholms län: En kvantitativ studie av fåglarna i jordbrukslandskapet2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the 1970s, a breeding bird survey was conducted to see how many birds are breeding in Sweden. This was done because the research at the time pointed out that there was a decrease in the number of bird species. This inventory became known as atlas inventory 1, and an additional inventory was done in the 2000s, which was called atlas inventory 2. The second inventory was carried out in order to see trends in bird population distribution and to be compared with atlas inventory 1. The purpose of this study was to examine if it is possible to compare the inventories with each other to see if there are any changes in the number of breeding birds in Sweden. The study was limited to the Stockholm report area, which includes all municipalities in Stockholm County except for Norrtälje. A limitation was also made to only examine agricultural birds, where six species were selected. The results show that the number of atlas squares with data for breeding birds within the Stockholm report area have decreased between atlas inventory 1 and atlas inventory 2. To obtain these results, information was retrieved from the website Artportalen, and was then compiled and processed in Excel and ArcMap. A comparison between the period 2013-2016 and atlas inventory 2 was also done, which showed a decrease in the number of atlas squares with available data, as well as a reduction in the number of observations of breeding birds.

    The Green Wave: How communication, advocacy andparticipation measures are included indocuments important for increase bicycling inStockholm City and Nacka Municipality2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The world is becoming increasingly urban. This puts pressure on a number of functions within cities, not the least the transportation system. Motorized traffic is responsible for a number of negative environmental effects, such as carbon dioxide emissions and particle pollution. To halt this development an increased share of bicyclists is needed. Stockholm County is an area with rapid urbanization. Therefore, a comparative study was undertaken to analyse how Stockholm City and Nacka Municipality are including communication, advocacy and participation measures in documents important for increased bicycling. This as those measures are important to increase the number of bicyclists. The analysis was undertaken by using two typologies, a modified version of the Transtheoretical Model of Change (TTM) to understand how the two cases include communication and advocacy measures whereas Arnstein’s Ladder of Citizens Participation was chosen to understand how participation is included in the documents. The findings suggest many similarities between the two cases but Nacka Municipality perform better with their use of social media, and the activities ”bicycle-friendly workplace” and ”winter bicycling”. From the findings three recommendations where provided: create bicycle councils to improve inclusion of bicyclists in the processes. Second, it is important to have different type of role models across the municipality, both in socio-economic strong and weak areas. And third, create dedicated outlets for bicycle issues, tentatively on a social media outlet. This will increase the status of bicycles, it will promote bicycling as a good transportation choice and it open ups channels for citizens interaction.

    Metagenomic Analysis of Subtidal Sediments from Polar and Subpolar Coastal Environments Highlights the Relevance of Anaerobic Hydrocarbon Degradation Processes2017In: Microbial Ecology, ISSN 0095-3628, E-ISSN 1432-184XArticle in journal (Refereed)
    Abstract [en]

    In this work, we analyzed the community structure and metabolic potential of sediment microbial communities in high-latitude coastal environments subjected to low to moderate levels of chronic pollution. Subtidal sediments from four low-energy inlets located in polar and subpolar regions from both Hemispheres were analyzed using large-scale 16S rRNA gene and metagenomic sequencing. Communities showed high diversity (Shannon's index 6.8 to 10.2), with distinct phylogenetic structures (<40% shared taxa at the Phylum level among regions) but similar metabolic potential in terms of sequences assigned to KOs. Environmental factors (mainly salinity, temperature, and in less extent organic pollution) were drivers of both phylogenetic and functional traits. Bacterial taxa correlating with hydrocarbon pollution included families of anaerobic or facultative anaerobic lifestyle, such as Desulfuromonadaceae, Geobacteraceae, and Rhodocyclaceae. In accordance, biomarker genes for anaerobic hydrocarbon degradation (bamA, ebdA, bcrA, and bssA) were prevalent, only outnumbered by alkB, and their sequences were taxonomically binned to the same bacterial groups. BssA-assigned metagenomic sequences showed an extremely wide diversity distributed all along the phylogeny known for this gene, including bssA sensu stricto, nmsA, assA, and other clusters from poorly or not yet described variants. This work increases our understanding of microbial community patterns in cold coastal sediments, and highlights the relevance of anaerobic hydrocarbon degradation processes in subtidal environments.

    Biofuel Production: Examining the development of sub-Saharan Africa through the concepts of land grabbing, environmental justice and different views on development theories2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper examines and problematize the effects of biofuel production by focusing on local communities in sub-Saharan Africa (SSA). The premise lays in a critique of neoliberal thoughts of development and the concept of sustainable development. The establishment of biofuel production in SSA has been depicted to carry with it opportunities of development for the rural population. However, there have been a big interest from foreign actors looking to invest in sub-Saharan biofuel production which have raced concern for land grabbing. A conflict of interest has emerged between Southern and Northern interests. A literature study is used as the method to examine reported outcomes on local communities in the proximity of biofuel production in order to determine if sub-Saharan biofuel production is established for the development need of SSA or the interest of the North. To analyze the results a theoretical framework has been constructed from concepts of large-scale land acquisition (land grabbing), environmental justice and the four worldviews market liberalism, institutionalism, bioenvironmentalism and social greens. The paper concludes that the large-scale production of biofuels is highly problematic due to the risk of land grabbing and Northern mitigation schemes are based on Southern lands raises the question of environmental justice. Depending on which worldview one adopts there can be several explanations to why this occur.

    We adapt … but is it good or bad? Locating the political ecology and social-ecological systems debate in reindeer herding in the Swedish Sub-Arctic: Locating the political ecology and social-ecological systems debate in reindeer herding in the Swedish Sub-Arctic2017In: Journal of political ecology, ISSN 1073-0451, E-ISSN 1073-0451, Vol. 24, 667-691 p.Article in journal (Refereed)
    Abstract [en]

    Reindeer herding (RDH) is a livelihood strategy deeply connected to Sami cultural tradition. This article explores the implications of two theoretical and methodological approaches for grasping complex socio-environmental relationships of RDH in Subarctic Sweden. Based on joint fieldwork, two teams – one that aligns itself with political ecology (PE) and the other with social-ecological systems (SES) – compared PE and SES approaches of understanding RDH. Our purpose was twofold: 1) to describe the situation of Sami RDH through the lenses of PE and SES, exploring how the two approaches interpret the same empirical data; 2) to present an analytical comparison of the ontological and epistemological assumptions of this work, also inferring different courses of action to instigate change for the sustainability of RDH. Key informants from four sameby in the Kiruna region expressed strong support for the continuation of RDH as a cultural and

    economic practice. Concerns about the current situation raised by Sami representatives centered on the cumulative negative impacts on RDH from mining, forestry and tourism. PE and SES researchers offered dissimilar interpretations of the key aspects of the RDH socio-economic situation, namely: the nature and scale of RDH systems; the ubiquitous role of conflict; and conceptualizations of responses to changing socio-environmental conditions. Due to these disparities, PE and SES analyses have radically divergent socio-political implications for what ought to be done to redress the current RDH situation.

    The role of horse keeping in transforming peri-urban landscapes: A case study from metropolitan Stockholm, Sweden2017In: Norsk Geografisk Tidsskrift, ISSN 0029-1951, E-ISSN 1502-5292, Vol. 71, no 3, 146-158 p.Article in journal (Refereed)
    Abstract [en]

    The authors analyze sustainable cultural landscapes through the lens of ecosystem services. Their case study focuses on transformation of the peri-urban landscape of the Stockholm region, Sweden. Peri-urban landscapes are characterized by diversified and fragmented land uses that are strongly related to urban lifestyles. The rapidly increasing trend for recreational horse keeping is replacing traditional agriculture. Horse keepers’ and local government perspectives on horse keeping are examined, as well as the related demand for ecosystem services, which affects the landscape. The article is based on government documents, interviews with local government officials, and field visits to 16 horse-keeping facilities in two municipalities. Horse keeping was found important for sustaining cultural ecosystem services related to a rural cultural landscape and for maintaining traditional agriculture that provides provisioning ecosystem services. However, several differences between traditional agriculture and horse keeping that affect the demand for ecosystem services related to land use were found to shift the focus from provisioning services to recreational services. The authors conclude that horse keeping, as an emerging crosscutting issue in peri-urban landscapes, needs new more integrative planning processes that account for the full range of ecosystem services and links between cultural services and ecosystem functioning.

    Transnational environmental collective action facing implementation constraints: the case of nutrient leakage in the Baltic Sea Action Plan2017In: Journal of Environmental Policy and Planning, ISSN 1523-908X, E-ISSN 1522-7200, Vol. 19, no 4, 408-422 p.Article in journal (Refereed)
    Abstract [en]

    While scholars have showed a long-standing interest for how to design effective environmental treaties and other international agreements, less interest has been paid to implementation phases of these agreements. This article takes the Eutrophication Segment in the Baltic Sea Action Plan as an example of a regional effort to reduce nutrient leakages, where national reporting of adopted strategies has been a key mechanism to improve implementation effectiveness. It is shown that although transnational collective action theory is a powerful tool to analyse underlying drivers and priorities in state implementation policies, a deeper analysis of domestic and external constraints can shed additional light on observed implementation gaps. Varying views among countries on, for example, the role of stakeholder participation, legitimacy and top-down governing versus multi-stakeholder governance approaches may comprise domestic constraints that make effective and efficient implementation problematic. In terms of external constraints, states’ balancing of action plan objectives versus other international commitments, such as other environmental treaties and EU Directives, is shown to potentially reduce implementation efficiency as well.

    Holocene stratigraphy of the Ångermanälven River estuary, Bothnian Sea2017In: Geo-Marine Letters, ISSN 0276-0460, E-ISSN 1432-1157, Vol. 37, no 3, 273-288 p.Article in journal (Refereed)
    Abstract [en]

    This study explores the Holocene depositional succession at the IODP Expedition 347 sites M0061 and M0062 in the vicinity of the Ångermanälven River estuary in the Bothnian Sea sector of the Baltic Sea in northern Scandinavia. Site M0061 is located in a coastal offshore setting (87.9 m water depth), whereas site M0062 is fully estuarine (69.3 m water depth). The dataset comprises acoustic profiles and sediment cores collected in 2007 and late 2013 respectively. Three acoustic units (AUs) were recognized. Lowermost AU1 is interpreted as a poorly to discontinuous stratified glaciofluvial deposit, AU2 as a stratified conformable drape of glaciolacustrine origin, and AU3 as a poorly stratified to stratified mud drift. A strong truncating reflector separates AU2 and AU3. Three lithological units (LUs) were defined in the sediment cores. LU1 consists of glaciofluvial sand and silt gradating into LU2, which consists of glaciolacustrine varves. A sharp contact interpreted as a major unconformity separates LU2 from the overlying LU3 (brackish-water mud). In the basal part of LU3, one debrite (site M0061) or two debrites (site M0062) were recognized. Information yielded from sediment physical properties (magnetic susceptibility, natural gamma ray, dry bulk density), geochemistry (total carbon, total organic carbon, total inorganic carbon and nitrogen), and grain size support the LU division. The depositional succession was formally subdivided into two alloformations: the Utansjö Alloformation and overlying Hemsön Alloformation; the Utansjö Alloformation was further subdivided into two lithostratigraphic formations: the Storfjärden and Åbordsön formations. The Storfjärden (sandy outwash) and Åbordsön (glaciolacustrine rhythmite) formations represent a glacial retreat systems tract, which started at ca. 10.6 kyr BP. Their deposition was mainly controlled by meltwater from the retreating ice margin, glacio-isostatic land uplift and the regressive (glacial) lake level. The Hemsön Alloformation (organic-rich brackish-water mud) represents a period of forced regression, starting possibly at ca. 9.5 kyr BP. At about 7 kyr BP, brackish water reached the study area as a result of the mid-Holocene marine flooding of the Baltic Sea Basin, but the rapid land uplift soon surpassed the associated (Littorina) transgression. Changed near-bottom current patterns, caused by the establishment of a permanent halocline, and the reduced sediment consistency caused by increased organic deposition resulted in a sharp and erosional base of the brackish-water mud. Estuarine processes and salinity stratification at site M0062 started to play a more important role. This study applies a combined allostratigraphic and lithostratigraphic approach over the conventional Baltic Sea stages. This approach makes it more straightforward to study this Baltic Sea deglaciation–postglacial sequence and compare it to other formerly glaciated shallow sea estuaries.

    Planning for sustainability in expansive metropolitan regions: exploring practices and planners’ expectations in Stockholm, Sweden2017In: European Planning Studies, ISSN 0965-4313, E-ISSN 1469-5944, 1-19 p.Article in journal (Refereed)
    Abstract [en]

    In Sweden, local and regional planning practices are faced with the challenge of managing rapid growth in expansive urban regions. However, spatial planning should also contribute to the fulfilment of formalized sustainability objectives and support sustainable development. This includes addressing cross-cutting sustainability issues that transcend established administrative and territorial boundaries. Thus, the management of sustainability issues requires attention from actors at different levels, and challenges how contemporary planning practices plan for development. Based in the expansive Stockholm region, this study explores the cross-level interaction in spatial planning and decision-making and planning practitioners’ experiences and apprehensions of contemporary municipal planning practices with a focus on statutory plans to achieve sustainability targets and objectives. The results show that municipal planning organizations are under pressure because of rapid urban expansion. It is concluded that the role, format and content of statutory as well as informal planning instruments are decisive for the cross-level interaction between planning levels. Moreover, planning instruments find new trajectories resulting in mismatches in expectations from planners at adjacent planning levels. This influences the interplay and preconditions for achieving national and regional sustainability targets and objectives. © 2017 Informa UK Limited, trading as Taylor & Francis Group

    Selective serotonin re-uptake inhibitors in the environment: Effects of citalopram on fish behaviour2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Selective serotonin re-uptake inhibitors (SSRIs) are a class of anxiolytic and anti-depressant drugs. SSRIs act on the evolutionarily ancient serotonergic system which is virtually identical throughout the vertebrate phylum. Serotonin is involved in a wide range of processes ranging from neuronal and craniofacial embryonic development to regulation of behaviour. However, SSRIs are also emerging pollutants, mainly entering the environment via sewage treatment plants. Since the serotonergic system is virtually identical in humans and other animals, exposed animals will be affected in similar ways as humans and suspicions are rising that ecologically important behaviours may be affected in subtle ways. Using the three-spined stickleback (Gasterosteus aculeatus) and zebrafish (Danio rerio) as model organisms, this thesis focuses on the behavioural effects of SSRIs in fish. The SSRI used throughout this thesis is citalopram, which has been found in fish in coastal areas of the Baltic Sea and other parts of the world.

    Effects on behaviour were investigated using several different tests measuring stress response, feeding behaviour, aggression and locomotor activity. Anxiolytic effects of 0.1 μg/l, 1.5 μg/l 15 μg/l were investigated as well as effects of 0.15 μg/l and 1.5 μg/l on feeding behaviour. Because serotonin is involved in the development of the nervous system, the effects of developmental exposure to 1.5 μg/l was studied after 100 days of remediation. Finally, because SSRIs rarely occur alone in natural waters, the effects on zebrafish of citalopram in a cocktail scenario, with the anxiogenic compound 17α-ethinyl estradiol (EE2 ) was also investigated. Citalopram was found to have anxiolytic effects on the three-spined stickleback at 0.1 μg/l, 1.5 μg/l and 15 μg/l.

    Citalopram also suppressed feeding behaviour within a week of exposure and at concentrations as low as 0.15 μg/l. Developmental exposure to 1.5 μg/l for 30 days was found to increase aggression and feeding behaviour and to reduce locomotor activity. The changes were persistent and remained in adult fish. In the cocktail scenario, citalopram in single-substance exposure had anxiolytic effects on one parameter in the novel tank test at 0.1 μg/l. Citalopram enhanced the anxiogenic effects of EE2 in the novel tank test, but in the scototaxis test citalopram appeared to counteract the effects of EE2. It is concluded that citalopram has the potential to affect behaviour in fish at concentrations that have been found in close proximity of sewage treatment plants.

    Developmental exposure to the SSRI citalopram causes long-lasting behavioural effects in the three-spined stickleback (Gasterosteus aculeatus)2017In: Ecotoxicology, ISSN 0963-9292, E-ISSN 1573-3017Article in journal (Refereed)
    Abstract [en]

    Selective Serotonin Re-uptake Inhibitors (SSRIs) are a class of psychotropic drugs used to treat depression in both adolescents and pregnant or breast-feeding mothers as well as in the general population. Recent research on rodents points to persistent behavioural effects of pre- and perinatal exposure to SSRI which last into adulthood. To study effects of developmental exposure in fish, three-spine sticklebacks were exposed to 1.5 µg/l of the SSRI citalopram in the ambient water for 30 days, starting two days post-fertilisation. After 100 days of remediation in clean water the fish were put through an extensive test battery. Feeding behaviour was tested as the number of bites against a piece of food and found to be increased in the exposed fish. Aggression levels were measured as the number of bites against a mirror image during 10 minutes and was also found to be significantly increased in the exposed fish. Novel tank behaviour and locomotor activity was tested in an aquarium that had a horizontal line drawn half-way between the bottom and the surface. Neither the latency to the first transition to the upper half, nor the number of transitions or the total time spent in the upper half was affected by treatment. Locomotor activity was significantly reduced in the exposed fish. The light/dark preference was tested in an aquarium where the bottom and walls were black on one side and white on the other. The number of transitions to the white side was significantly reduced in the exposed fish but there was no effect on the latency to the first transition or the total time spent in the white half. The results in the current study indicate that developmental SSRI exposure causes persistent behavioural effects in fish and contribute to the existing knowledge about SSRIs as environmental pollutants.

    Reconstructing Holocene temperature and salinity variations in the western Baltic Sea region: a multi-proxy comparison from the Little Belt (IODP Expedition 347, Site M0059)2017In: Biogeosciences, ISSN 1726-4170, E-ISSN 1726-4189, Vol. 14, 5607-5632 p.Article in journal (Refereed)
    Abstract [en]

    Sediment records recovered from the Baltic Sea during Integrated Ocean Drilling Program Expedition 347 provide a unique opportunity to study paleoenvironmental and climate change in central and northern Europe. Such studies contribute to a better understanding of how environmental parameters change in continental shelf seas and enclosed basins. Here we present a multi-proxy-based reconstruction of paleotemperature (both marine and terrestrial), paleosalinity, and paleoecosystem changes from the Little Belt (Site M0059) over the past  ∼  8000 years and evaluate the applicability of inorganic- and organic-based proxies in this particular setting. All salinity proxies (diatoms, aquatic palynomorphs, ostracods, diol index) show that lacustrine conditions occurred in the Little Belt until  ∼  7400 cal yr BP. A connection to the Kattegat at this time can thus be excluded, but a direct connection to the Baltic Proper may have existed. The transition to the brackish–marine conditions of the Littorina Sea stage (more saline and warmer) occurred within  ∼  200 years when the connection to the Kattegat became established after  ∼  7400 cal yr BP. The different salinity proxies used here generally show similar trends in relative changes in salinity, but often do not allow quantitative estimates of salinity. The reconstruction of water temperatures is associated with particularly large uncertainties and variations in absolute values by up to 8 °C for bottom waters and up to 16 °C for surface waters. Concerning the reconstruction of temperature using foraminiferal Mg  /  Ca ratios, contamination by authigenic coatings in the deeper intervals may have led to an overestimation of temperatures. Differences in results based on the lipid paleothermometers (long chain diol index and TEXL86) can partly be explained by the application of modern-day proxy calibrations to intervals that experienced significant changes in depositional settings: in the case of our study, the change from freshwater to marine conditions. Our study shows that particular caution has to be taken when applying and interpreting proxies in coastal environments and marginal seas, where water mass conditions can experience more rapid and larger changes than in open ocean settings. Approaches using a multitude of independent proxies may thus allow a more robust paleoenvironmental assessment.

    Indigeneidad, descolonización y la paradoja del desarrollismo extractivista en el Estado Plurinacional de Bolivia: Indigeneity, decolonization and the paradox of extractive development in the Plurinational State of Bolivia2017In: Revista Chilena de Derecho y Ciencia Política, ISSN 0718-9389, Vol. 8, no 1, 47-81 p.Article in journal (Refereed)
    Abstract [en]

    Historically, indigenous peoples have been marginalized and oppressed in the Bolivian political economy. During the presidency of Evo Morales, and under the 2009 Constitution, political, economic, social and cultural decolonization has become the central project for the transformation of the State and society. On the one hand, the new Constitution has been classified as one of the most progressive in the world with respect to ethnically defined rights; the indigenous ethical-philosophical principles of Suma Qamaña/Vivir Bien, referring to the harmonious relationship between individuals and nature, have been incorporated into the Constitution. On the other hand, these rights collide with broader social rights (defined by class) and also the rights of the State to extract and market natural resources (especially hydrocarbon extraction and mining) under the banner of redistributive justice, social reforms and the common good. This collision is defined in this study as the paradox of extractivist developmentalism. The article is based on an ethnographic work and problematizes the extractivist dilemma and the tensions between ethnic rights and class rights, thus contributing to debates about indigeneity and the challenges and dilemmas of decolonizing projects.

    Genetic Aspects of Environmental Disturbances in Marine Ecosystems: Studies of the Blue Mussel in the Baltic Sea2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Anthropogenic environmental changes can serve as drivers for evolutionary responses in wild populations. To predict the long-term impact of anthropogenic changes on populations, it is crucial to understand the genetic effects caused by these disturbances. The Baltic Sea is considered to be one of the world’s most contaminated seas, and the increase of anthropogenic chemical pollution is a major threat to its ecosystems. This thesis assesses the impact of harbors and sewage treatment plants on physiological traits and genetic structure of resident populations of blue mussels at replicated sites in the Baltic Sea. The initial evaluation of the overall genetic pattern in blue mussel populations in the Swedish West Coast, the Baltic Proper and the Bothnian Sea found genetic differentiation between the three water basins and a low genetic differentiation within each basin, especially within the Baltic Proper. Despite the low genetic differentiation among blue mussels within the Baltic Proper, a parallel genetic differentiation associated with sewage treatment plant effluents was found in this basin. This included genomic regions with a high degree of differentiation between reference sites and sites affected by sewage plants effluent. This genetic differentiation is suggested to be due to post-dispersal selection acting in each generation. In contrast, no parallel genetic differentiation was associated with harbors. We identified five genomic regions in blue mussels, showing strong signs of selection, shared among three out of four replicated reference sites and sites affected by sewage effluents in the Baltic Proper i.e. Askö, Tvärminne and Karlskrona. An initial characterization of these genomic regions revealed functions related to immune and endocrine responses, oxidative stress and shell formation. Our results indicate that selection caused by sewage effluents involves multiple loci. The same genomic regions are found across different locations in the Baltic Proper but there are also unique genomic regions at each location. No genotoxic or histopathological effects were found among blue mussels from sewage effluent-affected areas but a higher frequency of histological abnormalities in the digestive gland were observed in mussels from harbors.

    Regional genetic differentiation in the blue mussel from the Baltic Sea area2017In: Estuarine, Coastal and Shelf Science, ISSN 0272-7714, E-ISSN 1096-0015, 98-109 p.Article in journal (Refereed)
    Abstract [en]

    Connectivity plays an important role in shaping the genetic structure and in evolution of local adaptation. In the marine environment barriers to gene flow are in most cases caused by gradients in environmental factors, ocean circulation and/or larval behavior. Despite the long pelagic larval stages, with high potential for dispersal many marine organisms have been shown to have a fine scale genetic structuring. In this study, by using a combination of high-resolution genetic markers, species hybridization data and biophysical modeling we can present a comprehensive picture of the evolutionary landscape for a keystone species in the Baltic Sea, the blue mussel. We identified distinct genetic differentiation between the West Coast, Baltic Proper and Bothnian Sea regions, with lower gene diversity in the Bothnian Sea. Oceanographic connectivity together with salinity and to some extent species identity provides explanations for the genetic differentiation between the West Coast and the Baltic Sea (Baltic Proper and Bothnian Sea). The genetic differentiation between the Baltic Proper and Bothnian Sea cannot be directly explained by oceanographic connectivity, species identity or salinity, while the lower connectivity to the Bothnian Sea may explain the lower gene diversity. © 2016.

    Prospecting Biotechnologically-Relevant Monooxygenases from Cold Sediment Metagenomes: An In Silico Approach2017In: Marine Drugs, ISSN 1660-3397, E-ISSN 1660-3397, Vol. 15, no 4, 114Article in journal (Refereed)
    Abstract [en]

    The goal of this work was to identify sequences encoding monooxygenase biocatalysts with novel features by in silico mining an assembled metagenomic dataset of polar and subpolar marine sediments. The targeted enzyme sequences were Baeyer-Villiger and bacterial cytochrome P450 monooxygenases (CYP153). These enzymes have wide-ranging applications, from the synthesis of steroids, antibiotics, mycotoxins and pheromones to the synthesis of monomers for polymerization and anticancer precursors, due to their extraordinary enantio-, regio-, and chemo- selectivity that are valuable features for organic synthesis. Phylogenetic analyses were used to select the most divergent sequences affiliated to these enzyme families among the 264 putative monooxygenases recovered from the ~14 million protein-coding sequences in the assembled metagenome dataset. Three-dimensional structure modeling and docking analysis suggested features useful in biotechnological applications in five metagenomic sequences, such as wide substrate range, novel substrate specificity or regioselectivity. Further analysis revealed structural features associated with psychrophilic enzymes, such as broader substrate accessibility, larger catalytic pockets or low domain interactions, suggesting that they could be applied in biooxidations at room or low temperatures, saving costs inherent to energy consumption. This work allowed the identification of putative enzyme candidates with promising features from metagenomes, providing a suitable starting point for further developments.

    Forest governance and management across time: developing a new forest social contract2017Book (Refereed)
    Abstract [en]

    The influence of the past, and of the future on current-time tradeoffs in the forest arena are particularly relevant given the long-term successions in forest landscapes and the hundred years’ rotations in forestry. Historically established path dependencies and conflicts determine our present situation and delimit what is possible to achieve. Similarly, future trends and desires have a large influence on decision making. Nevertheless, decisions about forest governance and management are always made in the present – in the present-time appraisal of the developed situation, future alternatives and in negotiation between different perspectives, interests, and actors.

    This book explores historic and future outlooks as well as current tradeoffs and methods in forest governance and management. It emphasizes the generality and complexity with empirical data from Sweden and internationally. It first investigates, from a historical perspective, how previous forest policies and discourses have influenced current forest governance and management. Second, it considers methods to explore alternative forest futures and how the results from such investigations may influence the present. Third, it examines current methods of balancing tradeoffs in decision-making among ecosystem services. Based on the findings the authors develop an integrated approach – Reflexive Forestry – to support exchange of knowledge and understandings to enable capacity building and the establishment of common ground. Such societal agreements, or what the authors elaborate as forest social contracts, are sets of relational commitment between involved actors that may generate mutual action and a common directionality to meet contemporary challenges.

    The undatables: Quantifying uncertainty in a highly expanded Late Glacial-Holocene sediment sequence recovered from the deepest Baltic Sea basin—IODP Site M00632017In: Geochemistry Geophysics Geosystems, ISSN 1525-2027, E-ISSN 1525-2027, Vol. 18, no 3, 858-871 p.Article in journal (Refereed)
    Abstract [en]

    Laminated, organic-rich silts and clays with high dissolved gas content characterize sediments at IODP Site M0063 in the Landsort Deep, which at 459 m is the deepest basin in the Baltic Sea. Cores recovered from Hole M0063A experienced significant expansion as gas was released during the recovery process, resulting in high sediment loss. Therefore, during operations at subsequent holes, penetration was reduced to 2 m per 3.3 m core, permitting expansion into 1.3 m of initially empty liner. Fully filled liners were recovered from Holes B through E, indicating that the length of recovered intervals exceeded the penetrated distance by a factor of >1.5. A typical down-core logarithmic trend in gamma density profiles, with anomalously low-density values within the upper ∼1 m of each core, suggests that expansion primarily occurred in this upper interval. Thus, we suggest that a simple linear correction is inappropriate. This interpretation is supported by anisotropy of magnetic susceptibility data that indicate vertical stretching in the upper ∼1.5 m of expanded cores. Based on the mean gamma density profiles of cores from Holes M0063C and D, we obtain an expansion function that is used to adjust the depth of each core to conform to its known penetration. The variance in these profiles allows for quantification of uncertainty in the adjusted depth scale. Using a number of bulk 14C dates, we explore how the presence of multiple carbon source pathways leads to poorly constrained radiocarbon reservoir age variability that significantly affects age and sedimentation rate calculations.

    Dånvikens algblomning och dess sociala konsekvenser för fastighetsägare i Sjöudden/Gråstena i Salems kommun2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The recreational loss due to algal blooms is large even though recreation is important for human health and social cohesion. This study examines the social consequences of the autumn bloom in the lake Dånviken, Sweden, for property owners in close proximity to the lake and how future algal blooms can be prevented. Through sewerage analysis, survey, interview and conflict analysis, one can see that recreational opportunities have been threatened by the bloom through consequences such as bad odors and ruined beaches. Reduced recreation reduces social cohesion among residents as the bloom affected the social hotspots with connection to Dånviken negatively. With the help of conflict theory, we see the existence of different values ​​and uneven distribution of the power property owners have regarding the impact on Dånviken, which means increased risk of conflict in conjunction with algal blooms. The sewage situation looks better today compared to 2006 but still contributes to eutrophication through nutritional emissions. Since 2006, 54.5 % of the properties concerned have fixed their sewerage and the proportion of real estate’s connected to a sewer system has increased by 19.6 %, where the number of mini-treatment plant and soil- and infiltration beds has more than doubled. In order to prevent future blooms in Dånviken, the municipality must continue to demand better sewage and supervision, the water and sewage network also needs to be expanded among other measures. Continued studies in the area are important in order to better understand the social consequences of threatened recreational opportunities due to algal blooms.

    Where does the community start, and where does it end?: Including the seed bank to reassess forest herb layer responses to the environment2017In: Journal of Vegetation Science, ISSN 1100-9233, E-ISSN 1654-1103, Vol. 28, no 2, 424-435 p.Article in journal (Refereed)
    Abstract [en]

    Question: Below-ground processes are key determinants of above-ground plant population and community dynamics. Still, our understanding of how environmental drivers shape plant communities is mostly based on above-ground diversity patterns, bypassing below-ground plant diversity stored in seed banks. As seed banks may shape above-ground plant communities, we question whether concurrently analysing the above- and below-ground species assemblages may potentially enhance our understanding of community responses to environmental variation. Location: Temperate deciduous forests along a 2000 km latitudinal gradient in NW Europe. Methods: Herb layer, seed bank and local environmental data including soil pH, canopy cover, forest cover continuity and time since last canopy disturbance were collected in 129 temperate deciduous forest plots. We quantified herb layer and seed bank diversity per plot and evaluated how environmental variation structured community diversity in the herb layer, seed bank and the combined herb layer–seed bank community. Results: Seed banks consistently held more plant species than the herb layer. How local plot diversity was partitioned across the herb layer and seed bank was mediated by environmental variation in drivers serving as proxies of light availability. The herb layer and seed bank contained an ever smaller and ever larger share of local diversity, respectively, as both canopy cover and time since last canopy disturbance decreased. Species richness and β-diversity of the combined herb layer–seed bank community responded distinctly differently compared to the separate assemblages in response to environmental variation in, e.g. forest cover continuity and canopy cover. Conclusions: The seed bank is a below-ground diversity reservoir of the herbaceous forest community, which interacts with the herb layer, although constrained by environmental variation in e.g. light availability. The herb layer and seed bank co-exist as a single community by means of the so-called storage effect, resulting in distinct responses to environmental variation not necessarily recorded in the individual herb layer or seed bank assemblages. Thus, concurrently analysing above- and below-ground diversity will improve our ecological understanding of how understorey plant communities respond to environmental variation.

    Does the seed bank contribute to the build-up of a genetic extinction debt in the grassland perennial Campanula rotundifolia?2017In: Annals of Botany, ISSN 0305-7364, E-ISSN 1095-8290, Vol. 120, no 3, 373-385 p.Article in journal (Refereed)
    Abstract [en]

    Background and Aims: Habitat fragmentation threatens global biodiversity. Many plant species persist in habitat fragments via persistent life cycle stages such as seed banks, generating a species extinction debt. Here, seed banks are hypothesized to cause a temporal delay in the expected loss of genetic variation, which can be referred to as a genetic extinction debt, as a possible mechanism behind species extinction debts.

    Methods: Fragmented grassland populations of Campanula rotundifolia were examined for evidence of a genetic extinction debt, investigating if the seed bank contributed to the extinction debt build-up. The genetic make-up of 15 above- and below-ground populations was analysed in relation to historical and current levels of habitat fragmentation, both separately and combined.

    Key Results: Genetic diversity was highest in above-ground populations, though below-ground populations contained 8 % of unique alleles that were absent above-ground. Above-ground genetic diversity and composition were related to historical patch size and connectivity, but not current patch characteristics, suggesting the presence of a genetic extinction debt in the above-ground populations. No such relationships were found for the below-ground populations. Genetic diversity measures still showed a response to historical but not present landscape characteristics when combining genetic diversity of the above- and below-ground populations.

    Conclusions: The fragmented C. rotundifolia populations exhibited a genetic extinction debt. However, the role of the seed banks in the build-up of this extinction debt is probably small, since the limited, unique genetic diversity of the seed bank alone seems unable to counter the detrimental effects of habitat fragmentation on the population genetic structure of C. rotundifolia .

    Land Concessions and Rural Livelihoods in Mozambique: The Gap Between Anticipated and Real Benefits of a Chinese Investment in the Limpopo Valley2017In: Journal of Southern African Studies, ISSN 0305-7070, E-ISSN 1465-3893, Vol. 43, no 6, 1181-1198 p.Article in journal (Refereed)
    Abstract [en]

    In rural Mozambique, as in other African countries, large-scale land acquisitions are on the rise. This process is usually portrayed by host governments and investors as comprising win–win deals that can simultaneously boost agricultural productivity and combat poverty. This article focuses on one such investment, a large-scale Chinese land acquisition in the lower Limpopo valley, where attempts to modernise agriculture have occurred since colonial times. Based on an analysis of primary quantitative and qualitative data, this study explores livelihoods in the targeted area and local experiences and views regarding land loss and its implications. Our findings reveal a top-down process enabled by disregard for sound legislation, whereby land dispossession was followed by ‘take-it-or-leave-it’ opportunities that were unsuited to the most land-dependent livelihoods, particularly those of single-headed households. As the modernisation of the region is once again attempted through the promotion of large-scale agriculture, important historical continuities prevail. This study adds critical evidence to the discussion on the local development potential of land deals in Mozambique and other areas marked by similar democratic deficits.

    Combinatory effects of low concentrations of 17α-etinylestradiol and citalopram on non-reproductive behavior in adult zebrafish (Danio rerio)2017In: Aquatic Toxicology, ISSN 0166-445X, E-ISSN 1879-1514, Vol. 193, 9-17 p.Article in journal (Refereed)
    Abstract [en]

    Sewage treatment plant effluents contain a complex mixture of pharmaceuticals, personal care products and industrial chemicals, thus exposing aquatic organisms. Still, the consequences of exposure to combinations of different classes of drugs is largely unknown. In this study, we expose adult zebrafish (Danio rerio) males and females to low, environmentally relevant concentrations of the endocrine disrupting chemical 17α-ethinyl estradiol (EE2) and the selective serotonin re-uptake inhibitor (SSRI) citalopram, alone and in combination, and analyse three non-reproductive behaviours of importance for population fitness.

    Two weeks exposure to 0.1 and 0.5 ng/LEE2 resulted in increased anxiety in males in the scototaxis (light/dark preference) test. Significantly longer latency periods before entering the white zone and fewer visits in the white zone were observed in males exposed to both 0.1 and 0.5 ng/LEE2 compared to unexposed males. No significant effects of citalopram alone (0.1 and 0.5 µg/L) were observed in the scototaxis test. The combined exposures (0.1 ng/L EE2 + 0.1 µg/L citalopram and 0.5 ng/L EE2 + 0.5 µg/L citalopram) resulted in abolishment of the anxiogenic effects of EE2, with significantly shorter latency period (low dose) and more transitions to white (high and low dose) than in fish exposed to EE2 alone. No significant effects of either EE2, citalopramor the combination of the two were observed in females. In the novel tank test, significantly more transitions to the upper half of the tank were observed in males exposed to 0.1 µg/L citalopram alone compared to unexposed males while males exposed to 0.1 ng/lEE2 had significantly shorter latency period to enter the upper half. Exposure to the combination of the two low concentrations did, however, result in a significantly longer latency and fewer transitions to upper half compared to both control, EE2- and citalopram-exposed males. These males also spent significantly less time in the upper half than the fish exposed to 0.1 ng/l EE2 or 0.1 µg/l citalopram alone. No significant effects on novel tank behaviour were observed in females or males exposed to the higher concentrations. In the shoaling test, males exposed to 0.1 µg/L citalopram and females exposed to 0.5 ng/l EE2 made significantly fewer transitions away from peers while males exposed to 0.1 µg/L citalopram + 0.1 ng/l EE2 performed significantly more transitions than the fish exposed to 0.1 µg/L citalopram alone.

    In conclusion, this study shows that very low concentrations ofEE2, at or slightly above the predicted noeffect concentration (NOEC), affects anxiety in zebrafish males. Furthermore, citalopram, in spite of marginal effect of its own at such low levels, counteracts the response to EE2. This study represents an initial effort to understand the effects on water-living organisms of the cocktails of anthropogenic substances contaminating aquatic environments.

    Persistent Effects of Developmental Exposure to 17α-Ethinylestradiol on the Zebrafish (Danio rerio) Brain Transcriptome and Behavior2017In: Frontiers in Behavioral Neuroscience, ISSN 1662-5153, E-ISSN 1662-5153, Vol. 11, 69Article in journal (Refereed)
    Abstract [en]

    The synthetic estrogen 17α-ethinylestradiol (EE2) is an endocrine disrupting compound of concern due to its persistence and widespread presence in the aquatic environment. Effects of developmental exposure to low concentrations of EE2 in fish on reproduction and behavior not only persisted to adulthood, but have also been observed to be transmitted to several generations of unexposed progeny. To investigate the possible biological mechanisms of the persistent anxiogenic phenotype, we exposed zebrafish embryos for 80 days post fertilization to 0, 3 and 10 ng/L EE2 (measured concentrations 2.14 and 7.34 ng/L). After discontinued exposure, the animals were allowed to recover for 120 days in clean water. Adult males and females were later tested for changes in stress response and shoal cohesion, and whole-brain gene expression was analyzed with RNA sequencing. The results show increased anxiety in the novel tank and scototaxis tests, and increased shoal cohesion in fish exposed during development to EE2. RNA sequencing revealed 34 coding genes differentially expressed in male brains and 62 in female brains as a result of EE2 exposure. Several differences were observed between males and females in differential gene expression, with only one gene, sv2b, coding for a synaptic vesicle protein, that was affected by EE2 in both sexes. Functional analyses showed that in female brains, EE2 had significant effects on pathways connected to the circadian rhythm, cytoskeleton and motor proteins and synaptic proteins. A large number of non-coding sequences including 19 novel miRNAs were also differentially expressed in the female brain. The largest treatment effect in male brains was observed in pathways related to cholesterol biosynthesis and synaptic proteins. Circadian rhythm and cholesterol biosynthesis, previously implicated in anxiety behavior, might represent possible candidate pathways connecting the transcriptome changes to the alterations to behavior. Further the observed alteration in expression of genes involved in synaptogenesis and synaptic function may be important for the developmental modulations resulting in an anxiety phenotype. This study represents an initial survey of the fish brain transcriptome by RNA sequencing after long-term recovery from developmental exposure to an estrogenic compound.

    Participation and Legitimacy: Actor Involvement for Nature Conservation2017Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This PhD thesis in environmental science aims to contribute to the theoretical and empirical understanding of the relation between participation and legitimacy in multi-level environmental governance.

    It is widely assumed that actor involvement has great potential to improve the legitimacy of nature conservation through long-term acceptance and target achievement. However, local resource conflicts problematize the way a relation between participation and legitimacy is depicted on other administrative levels. Studies exploring the effect that participation has on legitimacy are relatively rare, especially in multi-level arrangements of coastal conservation.

    In this thesis the relation between participation and legitimacy on the local level is examined, as well as how this relation is conditioned by multi-level governance and power. The relation is empirical studied with two local implementation processes of the Helsinki Convention’s network of marine protected areas (HELCOM MPAs). The cases are located in Sweden.

    Sweden and the Baltic Sea region are in the forefront of participation in nature conservation, and therefore act as a strong case for the exploration of institutional participation. However, despite apparent political will and international support, the efficiency of actor involvement for nature conservation has been questioned, also for the HELCOM MPA and especially on the local level.

    Based on the results of this study, I question the assumption that weak legitimacy predominantly is an issue of insufficient information sharing. The findings show that involving actors to legitimize the adoption of strict adherence to a pre-established model of conservation likely fails to create long term support for conservation. Instead, relocation of power to the affected actors seems essential in order to make participation establish legitimacy. It appears important to create room for local influence in the design, management and implementation of a particular conservation area in the particular place/context. In both examined cases, there are elements of participation that support legitimacy, for example the development of a shared vision. There are also elements that hamper legitimacy, such as, for example, the high expectations different actors have on participation to reach consensus on protective values. These unmet expectations seem to fuel conflicts of interests among actors on different levels.

    Logics, assumptions and genre chains: a framework for poststructuralist policy analysis2017In: Critical Discourse Studies, ISSN 1740-5904, E-ISSN 1740-5912Article in journal (Refereed)
    Abstract [en]

    An unresolved aspect of the Logics Approach within Poststructuralist Discourse Theory (PDT) is how to operationalize its abstract theoretical concepts – of social, political and fantasmatic logics – for concrete textual analysis, especially of policy documents. Policies often institute new understandings, procedures or practices, something the logics, as originally articulated, fall somewhat short of capturing. To overcome these methodological challenges this article constructs a framework for poststructuralist policy analysis that brings together the Logics Approach with more textually oriented tools developed within Critical Discourse Analysis, namely assumptions and genre chains. For empirical illustration it draws on a case study of the European Union's adaptation policy in response to climate change. The resulting framework offers a means through which more implicit social and political logics can be examined, and contributes new insights to methodological debates around the use of the Logics Approach (and PDT more broadly), specifically in relation to critical policy analysis. The article concludes with seven observations of relevance for future studies and suggests avenues for further empirical and conceptual exploration.

    Mapping policies for surface water protection zones on forest land in the Nordic-Baltic region: Large differences in prescriptiveness and zone width.2017In: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 46, no 8, 878-893 p.Article in journal (Refereed)
    Abstract [en]

    The forest landscape across the Nordic and Baltic regions hosts numerous lakes and watercourses, which must be included in forest management. In this study, national policy designs regarding protection zones for surface waters on forest land were reviewed and compared for the Nordic countries, Estonia and Latvia. The focus was how each country regulates protection zones, whether they are voluntary or mandatory, and the rationale behind adopting a low or high degree of prescriptiveness. Iceland and Denmark had a low degree of policy prescriptiveness, whereas Norway, Estonia and Latvia had a high degree of prescriptiveness. Sweden and Finland relied to a large extent on voluntary commitments. The prescribed zone widths within the region ranged from 1 m to 5 km. The results indicated that land-use distribution, forest ownership structure and historical and political legacies have influenced the varying degrees of prescriptiveness in the region.

    Crossing disciplinary boundaries in environmental research: Interdisciplinary engagement across the Slovene research community2017In: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 574, 1492-1501 p.Article in journal (Refereed)
    Abstract [en]

    Contemporary approaches to environmental research are calling for a type of scientific inquiry that is able to bring together the natural and social sciences. This with the aim to advance our understanding of environmental issues and produce synthetic and actionable knowledge meant to address these. Yet, interdisciplinarity research of this type is a demanding and challenging pursuit; many have shown that in certain thematic areas and geographic regions practice falls behind discourse. We bring together ideas about interdisciplinary research collaborations (after Patricia L. Rosenfield) and interdisciplinary epistemic synthesis (after Julie T. Klein) that are used to analyse a sample of research projects funded (from 2006 to 2013) by the Slovene Research Agency. We triangulated interview data (with principal investigators) with document analysis and integrated these with other secondary data. Our results suggest for the sample of environmental projects to be interdisciplinary in a narrow sense, this prevalently within natural and life sciences with little input from the humanities and social sciences. Also, the results obtained suggest that environmental research with unambiguous problem solving objectives is preferred over research with a high degree of abstraction, as involved in theoretical and conceptual work.

    The social side of spatial decision support systems: Investigating knowledge integration and learning2017In: Environmental Science and Policy, ISSN 1462-9011, E-ISSN 1873-6416, Vol. 76, 177-184 p.Article in journal (Refereed)
    Abstract [en]

    Abstract Spatial decision support systems (SDSS) represent a step forward in efforts to account for the spatial dimension in environmental decision-making. The aim of SDSS is to help policymakers and practitioners access, interpret and understand information from data, analyses and models, and guide them in identifying possible actions during a decision-making process. Researchers, however, report difficulties in up-take of SDSS by the intended users. Some suggest that this field would benefit from investigation of the social aspects involved in SDSS design, development, testing and use. Borrowing insights from the literature on science-policy interactions, we explore two key social processes: knowledge integration and learning. Using a sample of 36 scientific papers concerning SDSS in relation to environmental issues, we surveyed whether and how the selected papers reported on knowledge integration and learning. We found that while many of the papers mentioned communication and collaboration with prospective user groups or stakeholders, this was seldom underpinned by a coherent methodology for enabling knowledge integration and learning to surface. This appears to have hindered SDSS development and later adoption by intended users.
