    Knowledge challenges for responsible supply chain management of chemicals in textiles - as experienced by procuring organisations2015In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 107, 130-136 p.Article in journal (Refereed)
    Abstract [en]

    A great number of chemicals - many of which are hazardous to human health and the environment - are used along the complex supply chains of textiles. These complexities and hazards make knowledge for understanding chemical properties and management practices at multiple nodes central to the responsible management of textile supply chains. This study investigates the knowledge requirements of, and the knowledge strategies used by, textile procuring organisations in response to both external stakeholders and internal pressure. Based on a qualitative study of small and medium-sized Swedish textile procuring organisations, the paper describes these knowledge challenges and analyses how efforts to meet them relate to expressed commitments and capabilities for responsible supply chain management (RSCM), as well as to organisational characteristics (i.e. whether the organisation is private or public, small or large, and whether textiles is a core or peripheral activity). It was found that several textile procuring organisations expressed commitment towards achieving RSCM. However, most organisations felt that they lacked capacity to rise to the challenge. There was a poor state of knowledge regarding many chemical substances and inherent difficulties in gaining knowledge of chemical risks and how to manage these. Moreover, the input of knowledge was limited and based on only a few key sources. Such factors proved to be obstacles for procuring organisations when attempting to facilitate responsible management upstream in complex supply chains.

    Tolerance to apical and leaf damage of Raphanus raphanistrum in different competitive regimes2015In: Ecology and Evolution, ISSN 2045-7758, E-ISSN 2045-7758, Vol. 5, no 22, 5193-5202 p.Article in journal (Refereed)
    Abstract [en]

    Tolerance to herbivory is an adaptation that promotes regrowth and maintains fitness in plants after herbivore damage. Here, we hypothesized that the effect of competition on tolerance can be different for different genotypes within a species and we tested how tolerance is affected by competitive regime and damage type. We inflicted apical or leaf damage in siblings of 29 families of an annual plant Raphanus raphanistrum (Brassicaceae) grown at high or low competition. There was a negative correlation of family tolerance levels between competition treatments: plant families with high tolerance to apical damage in the low competition treatment had low tolerance to apical damage in the high competition treatment and vice versa. We found no costs of tolerance, in terms of a trade-off between tolerance to apical and leaf damage or between tolerance and competitive ability, or an allocation cost in terms of reduced fitness of highly tolerant families in the undamaged state. High tolerance bound to a specific competitive regime may entail a cost in terms of low tolerance if competitive regime changes. This could act as a factor maintaining genetic variation for tolerance.

    Trophic transfer of naturally produced brominated aromatic compounds in a Baltic Sea food chain2016In: Chemosphere, ISSN 0045-6535, E-ISSN 1879-1298, Vol. 144, 1597-1604 p.Article in journal (Refereed)
    Abstract [en]

    Brominated aromatic compounds (BACs) are widely distributed in the marine environment. Some of these compounds are highly toxic, such as certain hydroxylated polybrominated diphenyl ethers (OH-PBDEs). In addition to anthropogenic emissions through use of BACs as e.g. flame retardants, BACs are natural products formed by marine organisms such as algae, sponges, and cyanobacteria. Little is known of the transfer of BACs from natural producers and further up in the trophic food chain. In this study it was observed that total sum of methoxylated polybrominated diphenyl ethers (MeO-PBDEs) and OH-PBDEs increased in concentration from the filamentous red alga Ceramium tenuicorne, via Gammarus sp. and three-spined stickleback (Gasterosteus aculeatus) to perch (Perca fluviatilis). The MeO-PBDEs, which were expected to bioaccumulate, increased in concentration accordingly up to perch, where the levels suddenly dropped dramatically. The opposite pattern was observed for OH-PBDEs, where the concentration exhibited a general trend of decline up the food web, but increased in perch, indicating metabolic demethylation of MeO-PBDEs. Debromination was also indicated to occur when progressing through the food chain resulting in high levels of tetra-brominated MeO-PBDE and OH-PBDE congeners in fish, while some penta- and hexa-brominated congeners were observed to be the dominant products in the alga. As it has been shown that OH-PBDEs are potent disruptors of oxidative phosphorylation and that mixtures of different congener may act synergistically in terms of this toxic mode of action, the high levels of OH-PBDEs detected in perch in this study warrants further investigation into potential effects of these compounds on Baltic wildlife, and monitoring of their levels.

    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.

    Participatory Deliberation, Risk Governance and Management of the Marine Region in the European Union2014In: Journal of Environmental Policy and Planning, ISSN 1523-908X, E-ISSN 1522-7200, Vol. 16, no 4, 497-515 p.Article in journal (Refereed)
    Abstract [en]

    In Europe, marine environmental risks are governed in a complex multi-level system. The role that the marine region could or should play as a level of risk governance has attracted growing attention of late. In this context, reference has been made to the regional sea as one level at which participatory processes in the future governing of European Union's (EU) marine environment and resources are required. The paper unfolds the particular challenges that one faces when trying to implement stakeholder and citizen participatory deliberation at marine region level. The EU Marine Strategy Framework Directive is highlighted as a key European environmental policy initiative and participatory deliberation at regional sea level is underlined as a requirement for the Directive's successful implementation. The paper's account of participatory deliberation is informed by perspectives of inclusive risk governance and reflexive governance. The discussion of the challenges draws on the distinction between horizontal and vertical risk governance. The paper's main argument is that frequently encountered problems of participatory deliberation are exacerbated when deliberation is to be carried out at the regional sea level, i.e. at a large trans-boundary scale. These problems include the 'inclusivity-effectiveness dilemma', a fragmentation of participation efforts and a loose connection to actual decision-making.

    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.

    From words to action: Lessons from active stakeholder participation in water management2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Water governance worldwide is going through a shift towards more holistic and participatory approaches. In Europe, the EU Water Framework Directive (WFD) adopted in 2000, aims at protecting surface water and groundwater. The WFD emphasizes the importance of stakeholder participation in planning and implementation of the directive, and in order to reach environmental objectives. However, the empirical findings are insufficient regarding how stakeholder participation can lead to improved decisions and implemented plans. In Sweden, a major water quality problem is eutrophication caused to a large extend by diffuse nutrient leakage from agriculture. Therefore, it is important to involve farmers in water management, since their participation can lead the commitment of mitigation measures for reduced nutrient leakage. The overall aim of this study is to contribute the knowledge and understanding of active stakeholder participation in water management, in particular how it can lead to implementation of water quality objectives. The thesis addresses stakeholder participation in eutrophication management in local Swedish catchments, with a particular focus on farmers’ participation in the commitment of mitigation measures. The results are based on case study research, involving four catchment areas in Sweden with severe eutrophication problems. The thesis identified socio-demographic factors, farmers’ knowledge, and the level of existing information and economic support for wetland creation, as factors affecting farmers’ willingness to participate in wetland creation to mitigate nutrient leakage. In the local catchment groups studied, farmers and other local stakeholders participated to discuss potential mitigation activities. In these, farmers emphasized other emitting actors’ responsibility and commitment in local action plans. Where this was realized, social capital within the group increased and led to further collaboration. The thesis also analyzed large-scale wetland programmes at catchment scale, where the organizational and institutional arrangements were central to realize farmers’ participation: inter-municipal agreements entailed sufficient resources, the organization involved the most relevant actors; and leadership resources were important. The thesis argues that organizing water management at a catchment level can be important to cope with challenges related to stake-holder participation for mitigating diffuse nutrient leakage. In particular for dissemination and collection of information, suggesting potential measures for all concerned actors, provide resources needed to realize actions, and to build trust and collaboration. The thesis also emphasized that stakeholder participation has to be underpinned by a genuine meaning, both for the initiators and the participants.

    Factors affecting farmers' willingness to participate in eutrophication mitigation: a case study of preferences for wetland creation in Sweden2016In: Ecological Economics, ISSN 0921-8009, E-ISSN 1873-6106, Vol. 130, 8-15 p.Article in journal (Refereed)
    Abstract [en]

    Local stakeholder participation in water management is emphasized in the EU Water Framework Directive (WFD). Wetland creation to mitigate nutrient leakage from agriculture is one example where participation of local farmers is needed. In this case study of the Himmerfjärden coastal catchment area, south of Stockholm, Sweden, we assessed both the importance of several demo-graphic factors, and of the main subsidy factors in the present Agri-Environmental Scheme (AES) for their effects on farmers’ willingness to create wetlands on their farms. The farm and farmer characteristics analyzed were age, gender, knowledge of the WFD, education, farm size, land ownership, current measures to reduce nutrient leakage and trust for other actors. The main factors from the AES were defined as five attributes in a discrete choice experiment approach related to the current agri-environmental policy instrument for wetland creation applied in the area. The results showed that approximately 30 % of the farmers were interested in wetland creation at their farms. The most common reason for not wanting to create a wetland was economic cost. Males were significantly more willing than females to create wetlands. Younger farmers were significantly more willing than older. Prior knowledge of the WFD increased willingness almost threefold, and land owners were significantly more willing than leaseholders. The choice experiment showed that higher cost ceiling for subsidies, higher compensation percentage and higher annual subsidies can significantly increase the willingness to create wetlands. However to attract also the remaining 70% of all farmers to join the AES we must look at other options than only using action based AES.

    Institutional development for stakeholder participation in local water management-An analysis of two Swedish catchments2015In: Land use policy, ISSN 0264-8377, E-ISSN 1873-5754, Vol. 43, 217-227 p.Article in journal (Refereed)
    Abstract [en]

    The EU Water Framework Directive (WFD) promotes a change of European water governance towards increased stakeholder participation and water management according to river basins. To implement the WFD, new institutional arrangements are needed. In Sweden, water councils have been established on the local level to meet the requirements of the WFD of a broad stakeholder involvement in water management. The aim of this paper is to contribute to the knowledge on institutional arrangements for meeting the WFD requirements on stakeholder participation in local water management. A case study of two adjacent catchments in southern Sweden is presented to analyze how institutional legacy affect organizational arrangements and stakeholder participation. Based on literature studies and semi-structure interviews, the case study is analyzed with special emphasis on the scope, the organization and the activities in practical water management in catchments. The result shows different institutional arrangements for water management, despite similarities of the catchments' characteristics and the regulatory framework on national and regional level.The study identifies four important factors regarding institutional arrangements for water councils and local stakeholder participation in water management. Firstly, an organization involving key stakeholders that are committed to the scope and goals of the water council and willing to provide resources for the implementation of the planned activities. Secondly, institutional arrangements that include a willingness for flexibility and awareness of the need to include the most relevant stakeholders. Thirdly, a clear leadership to drive the process to realize the specific goals and assess the outcome. Fourthly, voluntary involvement of farmers to take part in the implementation of the measures and contribute with knowledge and experiences regarding local conditions.

    Involving farmers in local water eutrophication management: lessons learnt from two Swedish catchmentsManuscript (preprint) (Other academic)
    Abstract [en]

    Stakeholder participation is increasingly important in water governance worldwide. In Europe, the EU Water Framework Directive (WFD) requires Member states to encourage the active involvement of stakeholders in planning and implementation of the WFD. In Sweden, eutrophication is one of the major water quality problems, which is primarily caused by diffuse nutrient leakage from agriculture. Farmers are, therefore, increasingly invited to participate in local water groups to discuss potential local action to mitigate nutrient leakage. This paper presents the lessons learnt from two Swedish catchments, where farmers and other local stakeholders participated in local water groups. Both catchments have severe eutrophication problems, and have been pointed out as “hot-spots” for wetland creation as mitigation measure. The overall aim of this study was to identify farmers’ primary concerns regarding local water management and wetland creation in particular. The results were based on data from meeting observation, interviews and a questionnaire. The paper identified four major aspects: (i) farmers’ concern about the commitment of other actors in local action plans; (ii) farmers desired improved information on local water management, monitoring of water quality, as well as improved information on wetland creation; (iii) farmers were concerned about phosphorus scarcity, and were interested in wetlands as phosphor traps; and, (iv) farmers requested developments in catchment-based platforms. Therefore, the paper suggests that organization of water management at catchment level could play an important role to cope with farmers’ primary concerns: Catchment platforms should disseminate information on local water management, identify information and data gaps, distribute responsibilities and commitment, enhance incentives for farmers’ commitment and enable trust-building. Consideration of these aspects could lead towards more robust forms for participation, inducing action and, consequently, improved water quality.

    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.

    Seeking Pathways Towards Improved Environmental Governance of the Baltic Sea2016In: Environmental Governance of the Baltic Sea / [ed] Michael Gilek, Mikael Karlsson, Sebastian Linke, Katarzyna Smolarz, Springer, 2016, 1, 229-246 p.Chapter in book (Refereed)
    Abstract [en]

    Governing marine environments is a highly complex and challenging enterprise. This applies particularly to the heavily exploited Baltic Sea for which despite extensive governance arrangements and a substantial scientific knowledge base, it is unlikely that the policy objective of ‘good environmental status’ is reached. Based on a review of governance arrangements linked to five large-scale environmental issues (eutrophication, overfishing, invasive alien species, chemical pollution and oil spills from shipping), this chapter aims to identify pathways and concrete ideas for institutional reform that may improve goal fulfilment. The results show that governance challenges differ substantially between environmental issues, implying a need for case-specific management reforms. For example, coping with extreme uncertainty is a key challenge in the chemical pollution case, whereas it seems more pertinent in the eutrophication case to address the complexity of nutrient pollution sources by adapting objectives and measures amongst sectoral policies to be in line with environmental ones. Furthermore, cross-case comparisons reveal a set of common vital functions (i.e. coordination, integration, interdisciplinarity, precaution, deliberation, communication and adaptability) that are needed in order to facilitate effective and efficient environmental governance in the long term. To promote these functions in Baltic Sea environmental governance, the chapter suggests pathways and institutional reforms aimed at improving multilevel and multisectoral integration, science-policy interactions and stakeholder participation. To further develop these ideas, it is proposed amongst other things that priority is given to setting up an international ‘Baltic Sea Policy Review Mechanism’, formed by cross-body and cross-stakeholder participation.

    Environmental Governance of the Baltic Sea2016 (ed. 1)Book (Refereed)
    Abstract [en]

    This edited volume presents a comprehensive and coherent interdisciplinary analysis of

    challenges and possibilities for sustainable governance of the Baltic Sea ecosystem by

    combining knowledge and approaches from natural and social sciences. Focusing on

    the Ecosystem Approach to Management (EAM) and associated multi-level, multi-sector

    and multi-actor challenges, the book provides up-to-date descriptions and analyses of

    environmental governance structures and processes at the macro-regional Baltic Sea

    level. Organised in two parts, Part 1 presents in-depth case studies of environmental

    governance practices and challenges linked to five key environmental problems -

    eutrophication, chemical pollution, overfishing, oil discharges and invasive species.

    Part 2 analyses and compares governance challenges and opportunities across the five

    case studies, focusing on governance structures and EAM implementation, knowledge

    integration and science support, as well as stakeholder communication and participation.

    Based on these cross-case comparisons, this book also draws a set of general conclusions

    on possible ways of improving the governance of the Baltic Sea by promoting what are

    identified as vital functions of environmental governance: coordination, integration,

    interdisciplinarity, precaution, deliberation, communication and adaptability.

    Environmental Governance of the Baltic Sea: Identifying Key Challenges, Research Topics and Analytical Approaches2016In: Environmental Governance of the Baltic Sea / [ed] Michael Gilek, Mikael Karlsson, Sebastian Linke, Katarzyna Smolarz, Springer, 2016, 1, 1-17 p.Chapter in book (Refereed)
    Abstract [en]

    The Baltic Sea ecosystem is subject to a wide array of societal pressures and associated environmental risks (e.g. eutrophication, oil discharges, chemical pollution, overfishing and invasive alien species). Despite several years of substantial efforts by state and non-state actors, it is still highly unlikely that the regionally agreed environmental objectives of reaching “good environmental status” by 2021 in the HELCOM BSAP (Baltic Sea Action Plan) and by 2020 in the EU Marine Strategy Framework Directive (MSFD) will be met. This chapter identifies key research topics, as well as presents analytical perspectives for analysing the gap between knowledge and action in Baltic Sea environmental governance. It does so by outlining important trends and key challenges associated with Baltic Sea environmental governance, as well as by summarising the scope and results of individual chapters of this interdisciplinary volume. The analysis reveals the development of increasingly complex governance arrangements and the ongoing implementation of the holistic Ecosystem Approach to Management, as two general trends that together contribute to three key challenges associated with (1) regional and cross - sectoral coordination and collaboration, (2) coping with complexity and uncertainty in science-policy interactions and (3) developing communication and knowledge sharing among stakeholder groups. Furthermore, to facilitate analysis of environmental governance opportunities and obstacles both within and across specific environmental issues, this chapter reviews the scientific literature to pinpoint key research issues and questions linked to the identified governance challenges.

    Late Holocene expansion of Siberian dwarf pine (Pinus pumila) in Kamchatka in response to increased snow cover as inferred from lacustrine oxygen-isotope records2015In: Global and Planetary Change, ISSN 0921-8181, E-ISSN 1872-6364, Vol. 134, no SI, 91-100 p.Article in journal (Refereed)
    Abstract [en]

    Holocene records of cellulose-inferred lake-water δ18O were produced from two lake-sediment sequences obtained in central and northern Kamchatka, Russian Far East. The sediment records share similar fluctuations in δ18O during the interval of ca. 5000-800calyr BP that correspond (inversely) with changes in K+ content of the GISP2 ice-core record from Greenland, a proxy for the relative strength of the Siberian High, suggesting control by climate-related variability in δ18O of regional precipitation. The dramatic expansion of Siberian dwarf pine (Pinus pumila) in northern and central Kamchatka between ca. 5000 and 4000calyr BP, as inferred from pollen records from the same and neighbouring sites, appears to have occurred at a time of progressively declining δ18O of precipitation. This development is interpreted as reflecting a regional cooling trend accompanied by increasing winter snowfall related to gradual intensification of the Siberian High from ca. 5000 to ca. 3000calyr BP. A thicker and more long-lasting snow cover can be assumed to have favoured P. pumila by providing a competitive advantage over other boreal and subalpine tree and shrub species in the region during the later part of the Holocene. These results, which are the first of their kind from Kamchatka, provide novel insight into the Holocene vegetational and climatic development in easternmost Asia, as well as long-term atmospheric circulation dynamics in Beringia.

    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.

    A Holocene History Of Dynamic Water Column Redox Conditions In The Landsort Deep, Baltic Sea2016In: American Journal of Science, ISSN 0002-9599, E-ISSN 1945-452X, Vol. 316, no 8, 713-745 p.Article in journal (Refereed)
    Abstract [en]

    The modern Baltic Sea is the world's largest anthropogenically forced anoxic basin. Using integrated geochemical records collected during Integrated Ocean Drilling Program (IODP) Expedition 347 from the deepest and one of the most reducing sub-basins in the Baltic Sea, Landsort Deep, we explore the degree and frequency of natural anoxia through the Baltic Holocene. A marked decrease in carbon-to-sulfur ratios (C/S) from the cores indicate the transition from the Baltic Ice Lake to the current brackish sea, which occurred about 8.5 kyrs B.P. Following this, laminations throughout sediments recording brackish deposition suggest sustained anoxia or extreme low oxygen, while high molybdenum (Mo) concentrations of >100 ppm and iron (Fe) geochemistry suggest water column sulfide accumulation, or euxinia, that persisted beyond seasonal timescales during deposition of two distinct sapropel units. Sedimentary Mo isotope values range from +1.11 to -0.50 permil, which are distinctly fractionated from modern Baltic seawater (+2.26 to -2.67 parts per thousand) and thus indicate that each of the sapropels experienced only weak and/or oscillatory euxinia-in contrast to the more stable euxinic conditions of more restricted basins. A shift in delta Mo-98 starting above the lower sapropel to a distinctly more negative range suggests particularly weak and oscillatory euxinia, with an enhanced contribution of manganese (Mn) redox cycling to Mo deposition relative to the lower portion of the profile. This conclusion is supported by extreme sedimentary Mn enrichments of up to 15 weight percent. We interpret the combined data to indicate episodic but major Baltic inflow events of saline and oxygenated North Sea water into the anoxic Landsort Deep that limited the concentrations and residence time of water column sulfide and caused episodic oxide deposition. Considering the temporal overlap between the most reducing conditions and periods of redox instability, we hypothesize that major Baltic inflows, as is observed today, lead to short-term instability while simultaneously supporting longer-term Baltic anoxia by strengthening the halocline. Ultimately, our results indicate that periods more reducing than the modern Baltic Sea have occurred naturally over the Holocene, but the characteristic dynamic saline inputs have historically prevented the relatively more widespread and stable anoxia observed in other classic restricted basins and will likely continue to do so.

    Coping and adaptation in socio-ecological problem structures: Towards an integrated framework for analyzing trans-boundary environmental problems in marine settings2015Report (Other academic)
    Abstract [en]

    The literature on governance of socio-ecological systems has been growing fast during the last one or two decades. However, sound theoretical underpinnings to these systems have not been sufficiently articulated and tied to existing theory, it is argued in this working paper. To address this shortcoming, this paper aims to elaborate on how the theoretical constructs  problem structure, collective choice theory and adaptive governance can be brought together to form a coherent analytical framework for analyzing trans-boundary environmental problems in marine settings. The argument that collective action problematiques may inhibit successful adaptation to environmental change among sovereign states is fundamental to this model. Given that governments tend to prefer national coping strategies where expected national rather than joint benefits are maximized, mutually beneficial cooperation often does not evolve and regional adaptation turn out piecemeal. It is concluded that in order to improve trans-national environmental governance, a better understanding of underlying drivers and countries’ incentives to take action is a necessary prerequisite.

    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.

    Towards an Ecosystem Approach to Management in Regional Marine Governance?: The Baltic Sea Context2013In: Journal of Environmental Policy and Planning, ISSN 1523-908X, E-ISSN 1522-7200, Vol. 15, no 2, 225-245 p.Article in journal (Refereed)
    Abstract [en]

    Currently, European marine governance seems to be undergoing significantchanges. From having been based largely on scientific expert knowledge, restricted riskassessments and governmental regulation, we are now witnessing a management turntowards holistic perspectives, the inclusion of stakeholders, adaptive governance, and coproductionof knowledge—the so-called ecosystem approach to management (EAM). Byusing the Baltic Sea as an example of these changes, we have taken a closer look at the2007 Baltic Sea Action Plan (BSAP) of the Helsinki Commission and the recent organizationalchanges within the International Council for the Exploration of the Sea (ICES).Informed by a Reflexive Governance perspective, the primary objective has been toanalyse the extent to which institutional preconditions for using an EAM exist in thesetwo cases. Our results show that even though the BSAP has been designed with anEAM approach as its core philosophy, existing implementation, financing, monitoring,and enforcement structures make it unlikely that actual management modes will changesignificantly in the near feature. Changes in the ICES have occurred as a result of aninternal restructuring process characterized by integrative and learning elements. It hasbeen shown that adopting a broad social science perspective and a reflexive governanceviewpoint can elucidate how factors such as inadequate institutional change, limitedcooperation over sector borders, and adjustment problems caused by path dependencycan threaten the successful turn towards the EAM in marine governance.

    Problems and potential solutions to effective communication among stakeholders in the Baltic Sea shipping for reduced air pollution: Outcomes from a survey2013In: Clean Shipping Currents, ISSN 2242-9794, Vol. 2, no 5, -33 p.Article in journal (Refereed)
    Abstract [en]

    This report presents the results of a web survey distributed to stakeholders in the Baltic Sea marine sector regarding environmental communication on air pollution from shipping. The survey was carried out in the spring and summer of 2012. Drawing on the literature on risk communication and environmental governance, the main focus was placed on so-called communication barriers, that is, possible hindrances to effective communication among stakeholders on how to reduce air pollution without threatening sector competitiveness. The results show that although there is a dense networking among stakeholders in this sector, there is a demand for improvements in communication in (a) exploratory phases among broad groups of stakeholders and (b) operational phases among selected groups of e.g. business and research teams. To facilitate the emergence of such improved communication, regional organizations such as HELCOM and EU could play important roles. Furthermore, it is shown that there is a perceived need among many stakehold­ers to step up the involvement of certain stakeholders, for example fuel companies, in collabora­tion on how to reduce pollution from shipping in cost-efficient ways. Finally, the results show that although continuous improvements of international regulation is a vital part of the governance of the marine sector, compliance will suffer if operators’ incentives are too strong in favor of not con­tributing to reduced pollution levels. Therefore, there is a strong need for innovative thinking on how to design such incentive schemes, not the least in relation to the continued implementation of Baltic Sea SECA and NECA as well as of the Baltic Sea Action Plan.

    Temporal genetic variability of landed Siganus sutor reveals a mixed stock fishery in coastal KenyaManuscript (preprint) (Other academic)
    Abstract [en]

    Artisanal fisheries in Kenya have been in decline since the 1980’s and are currently managed by gear restriction and no take zones. The fishery is a mixed species fishery but the Shoemaker spinefoot (Siganus sutor) comprise a large portion of the total catches. The sustainable use of these resources is dependent on informed assessment and management of the harvested species. In Kenya there is a lack of critical information about landings, fish stock productivity and genetic stock structure, and there is no knowledge of populations size or genetic variation of S. sutor. In this study we used the molecular marker, AFLP to investigate the genetic variation within and between sites of S. sutor landed along the 200 km coast of Kenya. We compared the spatial genetic variation among sites with the within site temporal genetic variation from a single site, adjacent to a number of spawning aggregations. Our results show that the there is genetic variation among the sites (spatial variation) and that the temporal genetic variation with in a six week period was about 1/5 of the spatial genetic variation. We believe these findings to be an important aspect to considered for both future scientific research as well as management.

    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

    Zygomycetes in Vesicular Basanites from Vesteris Seamount, Greenland Basin - A New Type of Cryptoendolithic Fungi2015In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, no 7, e0133368Article in journal (Refereed)
    Abstract [en]

    Fungi have been recognized as a frequent colonizer of subseafloor basalt but a substantial understanding of their abundance, diversity and ecological role in this environment is still lacking. Here we report fossilized cryptoendolithic fungal communities represented by mainly Zygomycetes and minor Ascomycetes in vesicles of dredged volcanic rocks (basanites) from the Vesteris Seamount in the Greenland Basin. Zygomycetes had not been reported from subseafloor basalt previously. Different stages in zygospore formation are documented in the studied samples, representing a reproduction cycle. Spore structures of both Zygomycetes and Ascomycetes are mineralized by romanechite-like Mn oxide phases, indicating an involvement in Mn(II) oxidation to form Mn(III, VI) oxides. Zygospores still exhibit a core of carbonaceous matter due to their resistance to degradation. The fungi are closely associated with fossiliferous marine sediments that have been introduced into the vesicles. At the contact to sediment infillings, fungi produced haustoria that penetrated and scavenged on the remains of fragmented marine organisms. It is most likely that such marine debris is the main carbon source for fungi in shallow volcanic rocks, which favored the establishment of vital colonies.

    Participation and deliberation in Swedish forest governance: The process of initiating a National Forest Program2016In: Forest Policy and Economics, ISSN 1389-9341, E-ISSN 1872-7050, Vol. 70, 137-146 p.Article in journal (Refereed)
    Abstract [en]

    Over the last two decades intergovernmental organizations have supported the initiation of National Forest Programs (NFPs): forums for joint deliberation by the state, private companies and NGOs that are intended to resolve conflicts over forestry and enhance sustainability. However, NFPs do not always reconcile conflicting perspectives or produce legitimate strategies for sustainable forestry. Thus, further analysis of NFPs' organization and processes is required, including exploration of effective means to address such challenges in early stages. These are key concerns of this paper, focusing on the first process to establish a Swedish NFP. Possibilities for an NFP to constitute a new arena for deliberation and consensus-building, producing forest policy statements and action plans considered legitimate by various stakeholders, are discussed. A number of key challenges are identified through a theoretical framework based on notions regarding the input and output legitimacy of collaborative governance. Analysis of official documentation, records of public hearings and stakeholder comments from the establishment phase in 2013–2015 suggests that the process will continually face a number of challenges, including balancing production and conservation values in the new bio-economy and securing equal stakeholder participation. The paper concludes with some remarks on the future of the NFP process.

    Risk Communication and the Role of the Public: Towards Inclusive Environmental Governance of the Baltic Sea?2016In: Environmental Governance of the Baltic Sea / [ed] Michael Gilek Mikael Karlsson Sebastian Linke Katarzyna Smolarz, Springer, 2016, 1, 205-227 p.Chapter in book (Refereed)
    Abstract [en]

    This chapter focuses on forms of and challenges for risk communication within regional environmental governance, based on an analysis of five environmental risks in the Baltic Sea – marine oil transportation, chemicals, overfishing, eutrophication and alien species. We address questions about how risks are framed and communicated and also analyse the role of communication in the governance process. Our main focus is on risk communication with the public (e.g. existing institutional arrangements and procedures of risk communication), but we also relate this analysis to discussions on communication with a broad range of actors and issues of stakeholder participation and communication. In the study we have identified some examples of relatively well-working risk communication with parts of the organised public in the Baltic Sea region (BSR), such as in fisheries or eutrophication, but also a number of different barriers and obstacles. Our key result from this study is that BSR consists of many national institutions for risk communication, but that there are hardly any centralised institutions for risk communication activities relating to environmental governance in the region. Another key conclusion is that public risk communication in this array of cross-national environmental risks is restricted mainly to (one-way) information. Against this backdrop and from our empirical and theoretical knowledge of risk communication and the role of the public, we finally suggest some ways for improvement.

    Governance of Chemicals in the Baltic Sea Region: A Study of Three Generations of Hazardous Substances2016In: Environmental Governance of the Baltic Sea / [ed] Michael Gilek, Mikael Karlsson, Sebastian Linke, Katarzyna Smolarz, Springer, 2016, 1, 97-123 p.Chapter in book (Refereed)
    Abstract [en]

    This study zooms in on public governance in the Baltic Sea region of three generations of notorious hazardous substances, namely, PCBs, PBDEs and PFOS/PFOA. Following regulation, PCB concentrations in the Baltic Sea have decreased substantially although they are still above pre-industrial levels. PBDE levels have also decreased in some places, but they too are well above targeted levels, whereas the situation for PFOS and in particular for PFOA has hardly improved at all. In the case of PCBs, while comprehensive measures took long to implement, initial preventive measures were taken early based on the precautionary principle. This contrasts with the cases of PBDEs, PFOS and PFOA, where the burden of proof on policy-makers has been high and hence caused severe delays in policymaking. There has, however, generally been a positive interplay in all three cases between the EU, which has legislated, and HELCOM, which has taken the role of concept and agenda setting. While environment-oriented policies, such as the Ecosystem Approach to Management under MSFD and BSAP, have grown in importance over time, polluter-oriented chemical legislation has been more important when it comes to final decision-making. Nevertheless, the general response has been reactive rather than proactive, and there is no indication that society responds faster today than in the past, at least not given the fact that awareness, experience and knowledge are greater today than a few decades back. Based on that insight, the article discusses various options for improving governance.

    Abstract [sv]

    Gapet är stort mellan miljömål och miljötillstånd i Östersjön. De omfattande insatser som görs av offentliga institutioner, näringsliv och allmänhet räcker inte. Samtidigt finns ett stort och växande engagemang från många politiker, företagare och enskilda för att stärka havsmiljöarbetet. När vi nu summerar ett större treårigt forskningsprojekt finner vi viktiga ledtrådar till vägar som kan leda till en förbättrad situation.

    Eutrophication and the Ecosystem Approach to Management: A Case Study of Baltic Sea Environmental Governance2016In: Environmental Governance of the Baltic Sea / [ed] Michael Gilek, Mikael Karlsson, Sebastian Linke, Katarzyna Smolarz, Springer, 2016, 1, 21-44 p.Chapter in book (Refereed)
    Abstract [en]

    This study investigates if and how present institutional structures and interactions between scientific assessment and environmental management are sufficient for implementing the ecosystem approach to management (EAM) in the case of Baltic Sea eutrophication. Concerning governance structures, a number of institutions and policies focus on issues relating to eutrophication. In many cases, the policies are mutually supportive rather than contradictory, as seen, for example, in the case of the mutually supportive BSAP and MSFD. The opposite is true, however, when it comes to the linkages with some other policy areas, in particular regarding agricultural policy, where the EU CAP subsidises intensive agriculture with at best minor consideration of environmental objectives, thereby undermining EAM. Enhanced policy coherence and stricter policies on concrete measures to combat eutrophication seem well needed in order to reach stated environmental objectives.  When it comes to assessment-management interactions, the science- policy interface has worked well in periods, but the more specific that policies have become, for example, in the BSAP case, the more question marks have been raised about science by affected stakeholders. At present, outright controversies exist, and EAM is far from realised in eutrophication policy in the Baltic Sea region. Besides coping with remaining uncertainties by improving the knowledge on problems and solutions– not least in terms of the socio-economic impacts of eutrophication – it may therefore be valuable to develop venues for improved stakeholder participation.

    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.

    Waterborne citalopram has anxiolytic effects and increases locomotor activity in the three-spine stickleback (Gasterosteus aculeatus)2016In: Aquatic Toxicology, ISSN 0166-445X, E-ISSN 1879-1514, Vol. 173, 19-28 p.Article in journal (Refereed)
    Abstract [en]

    Citalopram is an antidepressant drug, which acts by inhibiting the re-uptake of serotonin from the synaptic cleft into the pre-synaptic nerve ending. It is one of the most common drugs used in treatment of depression, it is highly lipophilic and frequently found in sewage treatment plant effluents and surface waters around the world. Citalopram and other selective serotonin re-uptake inhibitors have, at concentrations that occur in nature, been shown to have behavioural as well as physiological effects on fish and other animals. This study is the result of several different experiments, intended to analyse different aspects of behavioural effects of chronic citalopram exposure in fish. Our model species the three-spine stickleback is common in the entire northern hemisphere and is considered to be a good environmental sentinel species. Female three-spine sticklebacks were exposed to 0, 1.5 and 15μg/l nominal concentrations of citalopram for 21 days and subjected to the novel tank (NT) diving test. In the NT test, the fish exposed to 1.5μg/l, but not the 15μg/l fish made a significantly higher number of transitions to the upper half and stayed there for significantly longer time than the fish exposed to 0μg/l. The 15μg/l group, however, displayed a significantly lower number of freeze bouts and a shorter total freezing time. The test for locomotor activity included in the NT test showed that fish treated with 1.5 and 15μg/l displayed a significantly higher swimming activity than control fish both 5-7 and 15-17min after the start of the experiment. In the next experiment we compared fish exposed to 1.5μg/l and 0.15μg/l to pure water controls with regard to shoaling intensity and found no effect of treatment. In the final experiment the propensity of fish treated with 1.5μg/l to approach an unknown object and aggressive behaviour was investigated using the Novel Object test and a mirror test, respectively. The exposed fish ventured close to the unknown object significantly more often and stayed there for significantly longer time than unexposed fish. The aggression test yielded no statistically significant effects. It is concluded that citalopram changes the behaviour of the three-spine stickleback in a way that is likely to have ecological consequences and that it must not be considered an environmentally safe pharmaceutical.

    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.

    Environmentally relevant concentrations of citalopram partially inhibit feeding in the three-spine stickleback (Gasterosteus aculeatus)2015In: Aquatic Toxicology, ISSN 0166-445X, E-ISSN 1879-1514, Vol. 158, 165-170 p.Article in journal (Refereed)
    Abstract [en]

    Selective Serotonin Re-uptake Inhibitors (SSRI) are mood-altering, psychotropic drugs commonly used in the treatment of depression and other psychological illnesses. Many of them are poorly degraded in sewage treatment plants and enter the environment unaltered. In laboratory studies, they have been demonstrated to affect a wide range of behaviours in aquatic organisms. In this study we investigated the effect of a three-week exposure to 0.15 and 1.5 μg/l of the SSRI citalopram dissolved in the ambient water on the feeding behaviour in three-spine stickleback (Gasterosteus aculeatus). Feeding, measured as the number of attacks performed on a piece of frozen bloodworms during a 10-min period, was reduced by 30–40% in fish exposed to both 0.15 and 1.5 μg/l citalopram. The effects of the environmentally relevant concentration 0.15 μg/l on feeding, an important fitness characteristic, suggests that the ecological significance of environmental SSRI exposure may be pronounced.

    Holocene environmental changes in southern Kamchatka, Far Eastern Russia, inferred from a pollen and testate amoebae peat succession record2015In: Global and Planetary Change, ISSN 0921-8181, E-ISSN 1872-6364, Vol. 134, no SI, 142-154 p.Article in journal (Refereed)
    Abstract [en]

    High resolution palaeoenvironmental records in Far-Eastern Russia are rare, and the Kamchatka Peninsula is among the least studied areas of the region. This paper describes a record spanning the last ca. 11,000 yr, obtained from a bog in the southern part of Kamchatka. The radiocarbon dated core was analysed for pollen, testate amoebae, charcoal and loss-on-ignition (LOI).

    The vegetation during the early Holocene was dominated by grasses (Poaceae), birch (Betula) and heath (Ericaceae p. p.). Around 10,300 cal yr BP there was a substantial change in the vegetation cover to shrub alder (Alnus viridis s.l.) stands with sedges and ferns (Polypodiophyta) as well as herbs such as meadow rue (Thalictrum) in the understory. In the surroundings of Utka peatlands started to form. The variations in the vegetation cover were most probably caused by climatic changes. At the beginning of sediment accumulation, before 10,300 cal yr BP, the composition of the vegetation points to cooler summers and/or decreased annual precipitation. Around 10,300 cal yr BP, changes in vegetation occurred due to rising temperatures and/or changed water regimes. Increased abundancies of dry indicating testate amoebae after 9100 cal yr BP point to intermediate to dry soil conditions. Between 8600 and 7700 cal yr BP tree alder (Alnus incana) was widely spread at the site which probably indicates optimal environmental conditions. The tephra layer at 381–384.5 cm (ca. 8500 cal yr BP) produces a strong impact on the testate amoebae assemblages. At 7700 cal yr BP there was a sudden drop of A.incana in the local vegetation. From this time on, A.incana and also A.viridis decrease continuously whereas Betula gradually increases. The upper part of the sequence (after 6300 cal yr BP) shows higher abundancies of meadowsweet (Filipendula) and sweet gale (Myrica) pollen. After 6300 cal yr BP, changes in testate amoebae demonstrate variable soil moisture conditions at the site. Between 3700 and 1800 cal yr BP, wet conditions dominate as dry indicating testate amoebae decrease. After 1800 cal yr BP soil conditions become more variable again but this time with dry dominating testate amoebae.

    In contrast to surrounding regions, there is no evidence of trees such as spruce or larch growing in the surroundings of the site even though those trees are characteristic of many eastern Siberian sites. This difference might be because of the maritime influence of the Okhotsk Sea. Even dwarf pine (Pinus pumila), which is currently widely dispersed in northern Kamchatka, became part of the local vegetation only during the last 700 yr.
