    Política identitaria e interseccionalidad en la Venezuela Bolivariana: Reflexiones sobre el protagonismo de las mujeres de los sectores populares (2006-2013)2018In: Ontosemiótica, ISSN 2477-9482, Vol. 7, no 3, p. 35-59Article in journal (Refereed)
    Abstract [en]

    This article problematizes the empowerment of Venezuelan women of the popular sec­tors, who previously were marginalized in terms of gender, ethnicity and class. More specifically, the study focuses on the protagonist role of women in the Community Cou­ncils during 2006-2013. An additional interrelated aim of the study is to question the myth of Venezuela as the least racist country of Latin America. Theoretically, the study connects to an old debate of Leftist academia, namely on how to deal with the identi­tarian elements of class, ethnicity and gender in a broader socio-political setting. This viewpoint is contrasted with the theoretical-methodological framing of intersectionality, which considers the relationships between different identitarian elements at individual and collective level. The article shows that gender, class and ethnicity are intimately and complexly intertwined among the protagonists, and that these identity bases cross each other in local political situations. A further argument is that, generally, class-based identity appears to be superior to those of gender and ethnicity in socio-political settings. Methodologically, the study is based on critical reading of previous literature and, above all, ethnographic fieldwork in Venezuela between 1996 and 2013, including participa­tory observation and hundreds of interviews with actors involved in these political and socio-cultural processes.

    Sumak Kawsay y Buen-Vivir en Ecuador2017In: Conocimientos ancestrales y procesos de desarrollo: Nacionalidades Indígenas del Ecuador / [ed] Ana Dolores Verdú Delgado, Loja, Ecuador: Universidad Técnica Particular de Loja , 2017, p. 30-64Chapter in book (Refereed)
    Abstract [es]

    El interés de la academia por investigar sobre el término del Sumak Kawsay ha despegado a partir de su incursión en la Constitución del Ecuador en 2008. Su cuestionada traducción como Buen-Vivir ha despertado diversos debates epistemológicos y ontológicos. En la actualidad, son tres las corrientes de pensamiento que estudian al paradigma emergente del Buen-Vivir: indígena-culturalista, postdesarrollista-ecologista y socialista-estatista. Cada una de ellas ha interpretado de diferente manera los saberes indígenas relacionados con el Sumak Kawsay, lo que ha dado lugar a varios cuestionamientos, entre ellos, un posible extractivismo epistémico en el uso y contenido del término Buen Vivir. Además, en la práctica, la inclusión del Buen-Vivir en la Constitución ecuatoriana de 2008 y el reconocimiento de los derechos de la naturaleza ha dado lugar a una serie de críticas y dilemas político-ambientales debido a las políticas públicas neo-extractivistas implementadas por el gobierno de Rafael Correa. El presente capítulo tiene como objetivo ahondar y enfatizar varios de los debates intelectuales sobre el Sumak Kawsay y el Buen-Vivir, así como identificar algunos dilemas y desafíos en la implementación práctica de los principios y valores de estas visiones.

    The Andean Catch-22: ethnicity, class and resource governance in Bolivia and Ecuador2018In: Globalizations, ISSN 1474-7731, E-ISSN 1474-774X, Vol. 15, no 5, p. 636-654Article in journal (Refereed)
    Abstract [en]

    This study deals with the tensions and contradictions between resource governance, welfare policies, and the constitutionally recognized rights of nature and the indigenous peoples in Bolivia and Ecuador. We have identified a certain reductionism in current debates on these issues and propose a more systematic analytical focus on class and the class-ethnicity duality, as expressed in historical and contemporary indigenous struggles, and also confirmed via our ethnographic material. Drawing on the double bind as expressed in Joseph Heller’s Catch-22 wherein the protagonists face situations in which they do not have any choice to achieve a net gain, this article centres on how national governments have to choose between the protections of rights – in this case ethnic and environmental rights – and welfare provision financed by extractive revenues. From the perspective of ecologically concerned indigenous actors, the Catch-22 is articulated in the choice or compromise between universal welfarism on the one hand, and ethno-environmental concerns on the other hand. The article draws primarily on ecosocialist arguments and on indigenous-culturalist perspectives on Good Life (Sumak Kawsay or Vivir Bien). A central finding is the existence of awareness among involved actors – oppositional movements and government authorities – that the Catch-22 quandary and joint class-ethnic concerns are unavoidable ingredients in their discourses, struggles, and understandings of Good Life.

    Dilemas e desafios na construção do Estado plurinacional: Territorialidade, Indigeneidade e Diálogo Deliberativo Intercultural no Equador2017In: Revista MovimentAção, E-ISSN 2358-9205, Vol. 4, no 6, p. 178-202Article in journal (Refereed)
    Abstract [en]

    With the promulgation of the 2008 Constitution, Ecuador is formally a Plurinational and Intercultural State, the result of a process that had gained increasing societal legitimacy after decades of struggle by the indigenous peoples. After 2008, a central challenge for the indigenous organizations concerns the implementation of the principles and values of the Plurinational State. Different positions and interpretations are expressed among indigenous political actors. We problematize how they are expressed inwards, that is within the organization, and outwards, towards the surrounding political society. We refer to the second process as the intercultural deliberative dialogue. The main objective of the text is to analytically problematize the challenges and dilemmas associated with the Plurinational State project from the perspectives of the indigenous peoples. The theoretical framework draws on the literature on deliberative democracy in divided and/or multiethnic societies. The principal research question is: How are the complexities of implementing the Plurinational State reflected in the discourses of the actors involved? The plurinational project was contextually inserted in a complex relationship between territoriality and ethnic self-identification. We emphasize the centrality of territoriality for indigeneity and as an organizational and discursive strategy of the indigenous organizations. In discursive disputes about territoriality, different indigenous groups position themselves according to their historical relationship with the white-mestizo society. In this light, different temporalities of territoriality are constructed. This research is based on critical reading of the thematic literature and ethnographic work in Ecuador, including hundreds of interviews between 2001 and 2018 with politicians, intellectuals, and spokespersons of the indigenous organizations.

    Transmodernity and Socio-Historical Time in the Decolonization Process of the Plurinational State of Bolivia: La transmodernidad y el tiempo sociohistórico en el proceso descolonizador del Estado Plurinacional de Bolivia2018In: Revista de Estudios Sociales, ISSN 0123-885X, E-ISSN 1900-5180, no 65, p. 48-62Article in journal (Refereed)
    Abstract [en]

    This article analyzes how transmodernity has been expressed in the Plurinational State of Bolivia since 2009. It specifically focuses on the complexities involved in the reconstruction of the State and the road towards an intercultural society based on the constitutional acknowledgment of the values and praxis of plurinationality. This historic moment —with the reconstruction of the State and society based on the beliefs, traditions, epistemologies and ontologies of the indigenous peoples— symbolizes a particular social time and is the result of the silent survival of pre-colonial cultures which, over centuries, gradually transformed themselves alongside and in interaction with modernity, thus evolving into transmodern cultures. The establishmentof the Plurinational State has also legitimized the indigenous ethical-philosophical concept of SumaQamaña-Vivir Bien (“To Live Well”), which refers to a harmonious relationship between humans and Natureand is enshrined as a socio-political-cultural guideline and alternative to the logics of eurocentrism, anthropocentrism, individualism and capitalism. Methodologically, the study is based on years of ethnographic fieldwork in Bolivia and a critical reading of previous studies of such subjects.

    The Discursive Paradox of Environmental Conflict: Between Ecologism and Economism in Ecuador2018In: Forum for Development Studies, ISSN 0803-9410, E-ISSN 1891-1765, Vol. 45, no 3, p. 485-511Article in journal (Refereed)
    Abstract [en]

    Ecuador in times of the Rafael Correa government constitutes a prime example of the paradox of environmental conflict, in which all involved actors claim to represent the true vanguard concerning safeguarding of the environment and human conditions. The country presents the ecologically most progressive constitution in the world and also incorporates far-reaching recognition of indigenous peoples’ rights. Notwithstanding, the economy remains reliant on extractivism and the government argues that the revenues of extractive industries benefit the common good. Anchored in a distinction between environmentalism and ecologism, this article identifies and problematizes dominant narratives among the actors of the contentious discursive scenarios, and analyses how the state and its ecological-indigenous opposition aim to position themselves within the political conflict. The central questions are: How are eco-progressive politics perceived, defined and expressed in this setting of an intercultural and plurinational society economically reliant on natural resource extraction? Which values, interests and ontological assumptions are at stake and how are these expressed in the discursive struggle? The research is based on several years of ethnographic fieldwork, combined with critical reading of the previous literature and discourse analysis. The article contributes to politico-environmental debates in Ecuador and beyond and shows that environmental struggle is entangled in broader political disputes conditioned by global economic structures. It likewise communicates with debates on argumentative discourse and illustrates that the same core arguments can constitute the argumentative basis of rivalling actors in political struggles, thus emphasizing the centrality of the contextual framing amid ontological divides in contentious discursive settings.

    La paradoja político-ambiental ecuatoriana: The Ecuadorian Politico-Environmental Paradox2017In: Provincia, ISSN 1317-9535, no 37, p. 29-73Article in journal (Refereed)
    Abstract [en]

    Ecuador in times of the Rafael Correa government constitutes a perfect example of the politico-environmental paradox, which deals with conflicts in which all involved actors –State authorities as well as ecologist and Indigenous opposition - claim to represent the true vanguard concerning safeguarding of the environment and human conditions. On the one hand, Ecuador presents the most progressive Constitution in the world regarding the protection of nature and it also incorporates far-reaching recognition of Indigenous peoples. On the other hand, the developmentalist economy based on extractivism has continued during the period and the government argues that the revenues of extractive industries benefit the common good (welfare reforms). Based on several years of ethnographic fieldwork in Ecuador, combined with critical reading of previous literature and analysis of public discourses, political documents and material obtained through participatory observation, this article identifies and problematizes the dominant narratives among the actors of the contentious discursive scenarios. It also analyzes how State authorities and their adversaries aim at positioning themselves towards the other in relation to extractivism and ecological concerns. How are (progressive) environmental politics and ecological concerns perceived, defined and expressed by different actors?

    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, p. 98-109Article 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.

    Sewage treatment plant associated genetic differentiation in the blue mussel from the Baltic Sea and Swedish west coast2016In: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359, Vol. 4, article id e2628Article in journal (Refereed)
    Abstract [en]

    Human-derived environmental pollutants and nutrients that reach the aquatic environment through sewage effluents, agricultural and industrial processes are constantly contributing to environmental changes that serve as drivers for adaptive responses and evolutionary changes in many taxa. In this study, we examined how two types of point sources of aquatic environmental pollution, harbors and sewage treatment plants, affect gene diversity and genetic differentiation in the blue mussel in the Baltic Sea area and off the Swedish west coast (Skagerrak). Reference sites (REF) were geographically paired with sites from sewage treatments plant (STP) and harbors (HAR) with a nested sampling scheme, and genetic differentiation was evaluated using a high-resolution marker amplified fragment length polymorphism (AFLP). This study showed that genetic composition in the Baltic Sea blue mussel was associated with exposure to sewage treatment plant effluents. In addition, mussel populations from harbors were genetically divergent, in contrast to the sewage treatment plant populations, suggesting that there is an effect of pollution from harbors but that the direction is divergent and site specific, while the pollution effect from sewage treatment plants on the genetic composition of blue mussel populations acts in the same direction in the investigated sites.

    Multi biomarker analysis of pollution effect on resident populations of blue mussels from the Baltic Sea2018In: Aquatic Toxicology, ISSN 0166-445X, E-ISSN 1879-1514, Vol. 198, p. 240-256Article in journal (Refereed)
    Abstract [en]

    Anthropogenic pollution including metals, petroleum, toxins, nutrients and many others is a growing problem in the marine environment. These are important factors altering the environment and by that the fate of many local populations of marine organisms. The aim of this study was to assess the impact of selected point pollution sources on resident populations of the blue mussel (Mytilus edulis trossulus) in the Baltic Sea using multiple biomarker approach. The study used a nested sampling scheme in which sites from reference (REF) habitats are geographically paired with selected sites from sewage treatment plants (STP) and harbors (HAR). The results showed that mussels from harbors had a higher frequency of histological abnormalities in the digestive gland compared to mussels from sewage effluent affected areas and reference sites. However these mussels together with mussels from STPs had higher lipid content, body mass index (BMI) and gonado-somatic index (GSI) compared to mussels from reference sites. A marked spatial variability was found with a stronger toxicity of ambient environment affecting resident mussel populations in the Gulf of Gdańsk area, while an opposite pattern was found in Tvärminne area. Yet the blue mussels sampled in the Gulf of Gdańsk were characterized by the highest GSI and BMI values compared to Askö and Tvärminne populations. No differences in analyzed biomarker response related to species identity, measured by a species-specific genetic marker, were found indicative of strong genetic introgression in the Baltic Proper.

    Forest succession and population viability of grassland plants: long repayment of extinction debt in Primula veris.2016In: Oecologia, ISSN 0029-8549, E-ISSN 1432-1939, Vol. 181, no 1, p. 125-135Article in journal (Refereed)
    Abstract [en]

    Time lags in responses of organisms to deteriorating environmental conditions delay population declines and extinctions. We examined how local processes at the population level contribute to extinction debt, and how cycles of habitat deterioration and recovery may delay extinction. We carried out a demographic analysis of the fate of the grassland perennial Primula veris after the cessation of grassland management, where we used either a unidirectional succession model for forest habitat or a rotation model with a period of forest growth followed by a clear-cut and a new successional cycle. The simulations indicated that P. veris populations may have an extinction time of decades to centuries after a detrimental management change. A survey of the current incidence and abundance of P. veris in sites with different histories of afforestation confirmed the simulation results of low extinction rates. P. veris had reduced incidence and abundance only at sites with at least 100 years of forest cover. Time to extinction in simulations was dependent on the duration of the periods with favourable and unfavourable conditions after management cessation, and the population sizes and growth rates in these periods. Our results thus suggest that the ability of a species to survive is a complex function of disturbance regimes, rates of successional change, and the demographic response to environmental changes. Detailed demographic studies over entire successional cycles are therefore essential to identify the environmental conditions that enable long-term persistence and to design management for species experiencing extinction debts.

    The shellfish enigma across the Mesolithic-Neolithic transition in southern Scandinavia2016In: Quaternary Science Reviews, ISSN 0277-3791, E-ISSN 1873-457X, Vol. 151, p. 315-320, article id http://dx.doi.org/10.1016/j.quascirev.2016.09.004Article in journal (Refereed)
    Abstract [en]

    The well-known and widespread replacement of oysters (abundant during the Mesolithic period) by cockles and mussels in many Danish Stone Age shell middens ca. 5900 cal yrs BP coincides with the transition to agriculture in southern Scandinavia. This human resource shift is commonly believed to reflect changing resource availability, driven by environmental and/or climatic change at the Mesolithic-Neolithic transition rather than cultural choice. While several hypotheses have been proposed to explain the “Mesolithic-Neolithic oyster decline”, an explanation based on a sudden freshening of the inner Danish waters has received most attention. Here, for the first time, we test and refute this long-standing hypothesis that declining salinity explains the marked reduction in oysters identified within numerous shell middens across coastal Denmark at the Mesolithic-Neolithic transition using quantitative and qualitative salinity inference from several, independent proxies (diatoms, molluscs and foraminifera) from multiple Danish fjord sites. Alternatively, we attribute the oyster decline to other environmental causes (particularly changing sedimentation), ultimately driven by external climatic forcing. Critical application of such high-quality environmental archives can reinvigorate archaeological debates and can aid in understanding and managing environmental change in increasingly impacted coastal regions.

    Wildfires, responsibility and trust: public understanding of Sweden's largest wildfire2019In: Scandinavian Journal of Forest Research, ISSN 0282-7581, E-ISSN 1651-1891, Vol. 34, no 4, p. 319-328Article in journal (Refereed)
    Abstract [en]

    Wildfires present a growing risk to many countries, and climate change is likely to exacerbate this risk. This study analyzes how people directly affected by a wildfire understand its causes and consequences, as well as the future risk of wildfires. The point of departure is that social understanding of wildfires has an important influence on the consequences that emerge in the wake of a wildfire. The empirical case analyzed here is the largest forest fire in modern Swedish history, and the material basis of the study is a postal survey to all individuals directly affected by the fire. The results revealed a complex picture of the respondents’ understanding of the wildfire. Even if the fire was human caused, there was little blame toward forest companies and fire departments. Many positive consequences, such as a long-term increase in biodiversity, were attached to the disaster, and there was a belief that organizations will learn from it and take action to limit wildfires in the future. Simultaneously, the majority of the respondents believed that climate change may lead to an increased risk of forest fires in the future. These findings illustrate the complexity of people's perceptions of the fire and its aftermath.

    Science-Policy Interfaces in Baltic Sea Environmental Governance: Towards Regional Cooperation and Management of Uncertainty?2016In: Environmental Governance of the Baltic Sea / [ed] Gilek et al., Springer, 2016, 1, p. 173-203Chapter in book (Refereed)
    Abstract [en]

    This chapter investigates and compares the interactions between science and policy (risk assessments and risk management) in five cases of environmental governance of the Baltic Sea: eutrophication, fisheries, invasive alien species, chemical pollution and oil discharges. An efficient interplay between science and policy is important for successful environmental governance, which applies particularly to the Baltic Sea where all five risks pose serious threats to environmental, social and economic aspects of sustainability. We use science-policy theory and an analytical framework based on a categorisation of relevant management responses linked to different states of incomplete knowledge (risk, uncertainty, ambiguity, ignorance) to investigate two main characteristics of science-policy interfaces: (1) organisational structures and (2) procedural aspects of managing scientific uncertainties and stakeholder disagreements. The analyses reveal differences and similarities in institutional and organisational designs of the respective assessment-management interactions, as well as in terms of how scientific uncertainties, stakeholder disagreements and socio-political ambiguities are addressed. All the five science-policy interfaces expose science-based management approaches that commonly are not able to cope sufficiently well with the complexities, uncertainties and ambiguities at hand. Based on our cross-case analyses, we conclude by recommending five key aspects that need to be addressed to improve science-policy interactions in Baltic Sea environmental governance: (1) more adaptive organisational structures in terms of time, context and place dependency, (2) increased knowledge integrations, (3) a more careful consideration of stakeholder participation and deliberation, (4) better management of uncertainty and disagreements and (5) increased transparency and reflection in the communication of science-policy processes.

    Abstract [en]

    Sweden have already reached several of their goals for energy consumption, but the overall goal to become a fossil free society can still be seen as a driving force to keep developing renewable fuels. There is financial support for wetland construction, reduce impact on the climate, improve the natural environment, for developing new techniques and for biomass fuel plants. Still, cultivation of wetland crops for energy extraction are not yet well established on the energy market. After interviews with actors interested and knowledgeable in this field, this study presents driving forces and barriers affecting the development of this energy source. Driving forces comes from the ambition to move away from fossil fuels, decrease emissions of nutrients, make room for biodiversity, and provide services for the society while helping to reach climate and environmental goals. The barriers affecting this development is that special machines might be needed for handling of the crops and also to harvest the sensitive wetlands while large areas would be needed to increase profitability. The financial support available is not enough to cover the costs for production. Also, the prices on electricity and fossil fuels are low, which lowers the profitability for this type of energy source. Bioenergy producers have not yet found an effective way to extract energy from the crops. All of this makes the demand for energy crops from wetlands small. Despite this, wetlands provide several important ecosystem services and it is therefore recommended to use the management philosophy of multiple-use. With a multifunctional view of wetlands, the value of its ecosystem services can be added to the calculations of energy production and increase its role in reaching several national climate and environmental goals.

    Genetic differences between willow warbler migratory phenotypes are few and cluster in large haplotype blocks2017In: Evolution Letters, ISSN 2056-3744, Vol. 1, no 3, p. 155-168Article in journal (Refereed)
    Abstract [en]

    It is well established that differences in migratory behavior between populations of songbirds have a genetic basis but the actual genes underlying these traits remains largely unknown. In an attempt to identify such candidate genes we de novo assembled the genome of the willow warbler Phylloscopus trochilus, and used whole-genome resequencing and a SNP array to associate genomic variation with migratory phenotypes across two migratory divides around the Baltic Sea that separate SW migrating P. t. trochilus wintering in western Africa and SSE migrating P. t. acredula wintering in eastern and southern Africa. We found that the genomes of the two migratory phenotypes lack clear differences except for three highly differentiated regions located on chromosomes 1, 3, and 5 (containing 146, 135, and 53 genes, respectively). Within each migratory phenotype we found virtually no differences in allele frequencies for thousands of SNPs, even when comparing geographically distant populations breeding in Scandinavia and Far East Russia (>6000 km). In each of the three differentiated regions, multidimensional scaling-based clustering of SNP genotypes from more than 1100 individuals demonstrates the presence of distinct haplotype clusters that are associated with each migratory phenotype. In turn, this suggests that recombination is absent or rare between haplotypes, which could be explained by inversion polymorphisms. Whereas SNP alleles on chromosome 3 correlate with breeding altitude and latitude, the allele distribution within the regions on chromosomes 1 and 5 perfectly matches the geographical distribution of the migratory phenotypes. The most differentiated 10 kb windows and missense mutations within these differentiated regions are associated with genes involved in fatty acid synthesis, possibly representing physiological adaptations to the different migratory strategies. The ∼200 genes in these regions, of which several lack described function, will direct future experimental and comparative studies in the search for genes that underlie important migratory traits.

    Governing the salmon farming industry: Comparison between national regulations and the ASC salmon standard2019In: Marine Policy, ISSN 0308-597X, E-ISSN 1872-9460, Vol. 106, article id 103534Article in journal (Refereed)
    Abstract [en]

    Farmed salmon has become an important export commodity for many countries and regions. The expanding salmon aquaculture industry has, due to its rapid increase, resulted in environmental concerns, most notably relating to the interaction with wildlife, effects of effluents and discharges in local ecosystems, in some regions overuse of antibiotics and development of Antimicrobial Resistance (AMR) and high dependence on fish resources in feeds. As a response to these concerns, the industry has strengthened their efforts to improve practices and private led sustainability initiatives, including certification and eco-labelling, has become increasingly important. This study examines the differences between salmon farming governance policies in the four largest salmon producing regions; Norway, Chile, Scotland (UK) and British Columbia (Canada) and the Aquaculture Stewardship Council's (ASC) salmon standard. The purpose of the study is to clarify how the standard from a well-established eco-certification program compares to national or regional conventional standards, using additionality as measuring method. The paper concludes that at present the ASC standard has mainly three strong advantages over existing regional/national standards and these relate to; escape numbers allowed, antibiotic usage and fish resources in feed. Changing these three main divergences in the national/regional regulations would significantly improve some of the main sustainability issues with uncertified salmon farming. The study also finds that the potential additionality of the ASC standard can differ between regions, with the highest difference in Chile and lowest in Norway.

    Decline in lichen biodiversity on oak trunks due to urbanization2014In: Nordic Journal of Botany, ISSN 0107-055X, E-ISSN 1756-1051, Vol. 32, no 4, p. 518-528Article in journal (Other academic)
    Abstract [en]

    Biodiversity often suffers from urbanization. In the present study, we focused on how the duration of urbanization affects the richness of 17 epiphytic lichen species and their cover on large oaks in urban environments in a city of 100 000 inhabitants in southeast Sweden. We also surveyed trees in adjacent rural areas, selected to have similar distributions of tree trunk circumference and surrounding oak density (within 300 m). Lichen richness and cover were lower on urban trees compared to rural trees. Furthermore, richness and cover decreased with the length of time that urban trees had been surrounded by houses. Most of the species that were analysed demonstrated a decline in occurrence with respect to the duration of housing development. The reduction in the probability of occurrence varied from 60% (Calicium viride, Evernia prunastri), 80% (Chrysothrix candelaris) to 90% (Ramalina spp.) during the considered 160-year period of urbanization. Therefore, even if valuable trees survive over the course of development, their lichen biota is likely to become depleted over time. © 2014 The Authors.

    Plant species identity and soil characteristics determine rhizosphere soil bacteria community composition in European temperate forests2019In: FEMS Microbiology Ecology, ISSN 0168-6496, E-ISSN 1574-6941, Vol. 95, no 6, article id fiz063Article in journal (Refereed)
    Abstract [en]

    Soil bacteria and understorey plants interact and drive forest ecosystem functioning. Yet, knowledge about biotic and abiotic factors that affect the composition of the bacterial community in the rhizosphere of understorey plants is largely lacking. Here, we assessed the effects of plant species identity (Milium effusum vs Stachys sylvatica), rhizospheric soil characteristics, large-scale environmental conditions (temperature, precipitation and nitrogen (N) deposition), and land-use history (ancient vs recent forests) on bacterial community composition in rhizosphere soil in temperate forests along a 1700 km latitudinal gradient in Europe. The dominant bacterial phyla in the rhizosphere soil of both plant species were Acidobacteria, Actinobacteria and Proteobacteria. Bacterial community composition differed significantly between the two plant species. Within plant species, soil chemistry was the most important factor determining soil bacterial community composition. More precisely, soil acidity correlated with the presence of multiple phyla, e.g. Acidobacteria (negatively), Chlamydiae (negatively) and Nitrospirae (positively), in both plant species. Large-scale environmental conditions were only important in S. sylvatica and land-use history was not important in either of the plant species. The observed role of understorey plant species identity and rhizosphere soil characteristics in determining soil bacterial community composition extends our understanding of plant-soil bacteria interactions in forest ecosystem functioning.

    Local soil characteristics determine the microbial communities under forest understorey plants along a latitudinal gradient2019In: Basic and Applied Ecology, ISSN 1439-1791, E-ISSN 1618-0089, Vol. 36, p. 34-44Article in journal (Refereed)
    Abstract [en]

    The soil microbial community is essential for maintaining ecosystem functioning and is intimately linked with the plant community. Yet, little is known on how soil microbial communities in the root zone vary at continental scales within plant species. Here we assess the effects of soil chemistry, large-scale environmental conditions (i.e. temperature, precipitation and nitrogen deposition) and forest land-use history on the soil microbial communities (measured by phospholipid fatty acids) in the root zone of four plant species (Geum urbanum, Milium effusum, Poa nemoralis and Stachys sylvatica) in forests along a 1700km latitudinal gradient in Europe. Soil microbial communities differed significantly among plant species, and soil chemistry was the main determinant of the microbial community composition within each plant species. Influential soil chemical variables for microbial communities were plant species-specific; soil acidity, however, was often an important factor. Large-scale environmental conditions, together with soil chemistry, only explained the microbial community composition in M. effusum and P. nemoralis. Forest land-use history did not affect the soil microbial community composition. Our results underpin the dominant role of soil chemistry in shaping microbial community composition variation within plant species at the continental scale, and provide insights into the composition and functionality of soil microbial communities in forest ecosystems.

    Plant-soil feedbacks of forest understorey plants transplanted in nonlocal soils along a latitudinal gradient2019In: Plant Biology, ISSN 1435-8603, E-ISSN 1438-8677, Vol. 21, no 4, p. 677-687Article in journal (Refereed)
    Abstract [en]

    Climate change is driving movements of many plants beyond, as well as within, their current distributional ranges. Even migrant plants moving within their current range may experience different plant-soil feedbacks (PSFs) because of divergent nonlocal biotic soil conditions. Yet, our understanding to what extent soil biotic conditions can affect the performance of within-range migrant plants is still very limited. We assessed the emergence and growth of migrant forest herbs (Milium effusum and Stachys sylvatica) using soils and seeds collected along a 1,700 km latitudinal gradient across Europe. Soil biota were manipulated through four soil treatments, i.e., unsterilized control soil (PSFUS ), sterilized soil (PSFS ), sterilized soil inoculated with unsterilized home soil (PSFS+HI ) and sterilized soil inoculated with unsterilized foreign soil (PSFS+FI , expected to occur when both plants and soil biota track climate change). Compared to PSFS , PSFUS had negative effects on the growth but not emergence of both species, while PSFS+FI only affected S. sylvatica across all seed provenances. When considering seeds' origins, seedling emergence and growth responses to nonlocal soils depended on soil biotic conditions. Specifically, the home-away distance effect on seedling emergence differed between the four treatments, and significant responses to chemistry either disappeared (M. effusum) or changed (S. sylvatica) from PSFUS to PSFS . Soil biota emerge as an important driver of the estimated plant migration success. Our results of the effects of soil microorganisms on plant establishment provide relevant information for predictions of the distribution and dynamics of plant species in a changing climate.

    Systematic reviews of qualitative evidence for environmental policy and management: An overview of different methodological options2019In: Environmental Evidence, ISSN 2047-2382, E-ISSN 2047-2382, Vol. 8, no 1, article id 24Article in journal (Refereed)
    Abstract [en]

    Qualitative research related to the human dimensions of conservation and environment is growing in quantity. Rigorous syntheses of such studies can help develop understanding and inform decision-making. They can combine findings from studies in varied or similar contexts to address questions relating to, for example, the lived experience of those affected by environmental phenomena or interventions, or to intervention implementation. Researchers in environmental management have adapted methodology for systematic reviews of quantitative research so as to address questions about the magnitude of intervention effects or the impacts of human activities or exposure. However, guidance for the synthesis of qualitative evidence in this field does not yet exist. The objective of this paper is to present a brief overview of different methods for the synthesis of qualitative research and to explore why and how reviewers might select between these. The paper discusses synthesis methods developed in other fields but applicable to environmental management and policy. These methods include thematic synthesis, framework synthesis, realist synthesis, critical interpretive synthesis and meta-ethnography. We briefly describe each of these approaches, give recommendations for the selection between them, and provide a selection of sources for further reading. © 2019 The Author(s).

    Microbial biomass turnover times and clues to cellular protein repair in energy-limited deep Baltic Sea sediments2019In: FEMS Microbiology Ecology, ISSN 0168-6496, E-ISSN 1574-6941, Vol. 95, no 6, article id fiz068Article in journal (Refereed)
    Abstract [en]

    The discovery of active microbial life deeply buried beneath the seafloor has opened important questions: how do microorganisms cope with extreme energy limitation, what is their metabolic activity, and how do they repair damages to essential biomolecules? We used a D:L-amino acid model to calculate microbial biomass turnover times. We used a metagenome and metatranscriptome analysis to investigate the distribution of the gene that encodes Protein-L-iso aspartate(D-aspartate) O-methyltransferase (PCMT), an enzyme which recognizes damaged L-isoapartyl and D-aspartyl residues in proteins and catalyzes their repair. Sediment was retrieved during the Integrated Ocean Drilling Program (IODP) Expedition 347 from Landsort Deep and the Little Belt in the Baltic Sea. The study covers the period from the Baltic Ice Lake ca. 13 000 years ago to the present. Our results provide new knowledge on microbial biomass turnover times and protein repair in relation to different regimes of organic matter input. For the first time, we show that the PCMT gene was widely distributed and expressed among phylogenetically diverse groups of microorganisms. Our findings suggest that microbial communities are capable of repairing D-amino acids within proteins using energy obtained from the degradation of a mixture of labile compounds in microbial necromass and more recalcitrant organic matter.

    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, article id 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.

    An Investigation of the Role of Social Dynamics in Conversion to Sustainable Integrated Mangrove-Shrimp Farming in Ben Tre Province, Vietnam2018In: Singapore journal of tropical geography, ISSN 0129-7619, E-ISSN 1467-9493, Vol. 39, no 3, p. 421-437Article in journal (Refereed)
    Abstract [en]

    In the coastal area of the Vietnamese Mekong Delta, much of the mangrove forest has been cut to make space for expansion of industry and aquaculture. Export-oriented shrimp farming is a particularly fast-growing business. Nonetheless, the importance of tropical mangrove forest ecosystems for coastal protection and marine biodiversity is widely recognized. The Vietnamese government, supported by non-governmental organizations and donors, has sought to restore mangrove forest. To this end, the government has promoted mixed or integrated mangrove-shrimp systems in which farmers maintain at least 40 per cent of their area under mangrove cover. Since 2012, mangrove reforestation, care and protection has benefited from local authority stimulus as well. Multiple studies have examined the condition of the mangrove forest in Ben Tre and other coastal provinces of the Mekong Delta. However, no research has investigated the role of social dynamics in farmers' willingness to shift to, or maintain, integrated mangrove-shrimp systems. Specifically, the influence of information, group dynamics and social learning on farmer decision-making is poorly understood and, indeed, hardly investigated in Vietnam. This article reports on a study of social processes in three communes in Binh Dai District, Ben Tre Province, Vietnam. We conducted 42 semi-structured interviews (with 34 farmers and eight local officials) and used secondary data. Our preliminary findings indicate that social dynamics in these communes were issue-driven and played an important role in farmers' decisions to adopt, or convert to, the integrated mangrove-shrimp farming system. Television, radio, the internet, books, neighbours and training courses all had some influence in farmer decision-making processes. However, our findings suggest that the accessibility, usefulness, relevance and approach of these communication methods must be improved if they are to adequately inform and support local farmers.

    100 år av miljöförändringar som de registrerats i Hallsfjärden, västra Östersjön: En biostratigrafisk studie om vad bevarade kiselalger i sediment kan berätta om tidigare miljöförhållande i Hallsfjärden.2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Diatoms are microscopic, photosynthetic, single-celled organisms that are useful in studies of water qualities (eg pH, nutrients, salinity). By analyzing changes in the species composition of diatoms back in time, gives an opportunity to interpret the marine environment affected by various factors (Andren et al, 1999). The aim of the study was to study changes in diatom abundance and composition in Hallsfjärden, a bay in the Baltic Sea located north of Himmerfjärden in Södertälje. The site was chosen because it is a bay that is assumed to have a large environmental impact due to external factors such as increased population growth, water treatment plants, industrial areas, dredging and a link to Lake Mälaren. The purpose of the study therefore to investigate whether there was an environmental impact in Hallsfjärden, in order to draw conclusions about what happened in the area and what has affected the water the last 100 years.

         The survey is conducted by sampling sediment cores, studied by biostratigraphy of fossil diatoms to reconstruct past environmental conditions. The results of the analysis showed that oxygen deficiency was a particular problem, which is related to the eutrophication that are threatening some diatoms and thereby changes the species composition of ecosystems in Hallsfjärden. A plausible interpretation of the analyze results is that Hallsfjärden was adversely affected by the Södertalje area's population growth and Himmerfjärdsverkets startup by high emissions of nutrients. It has on the other hand appeared a positive impact for Himmerfjärdsverkets gradually improved purification with clearer water conditions. Hallsfjärden have proved to be a particularly sensitive ecosystem in this study, with low salinity and strong thermocline, which means that it is more affected by eutrophication and pollution in its drainage area. This causes a problem of eutrophication in Hallsfjärden due to the bay showing the influence of the surrounding areas and its emissions, which later exports further to the Baltic Sea via Himmerfjärden with the southbound flow.

    Anthropogenic and climatic impacts on a coastal environment in the Baltic Sea over the last 1000 years2018In: Anthropocene, E-ISSN 2213-3054, Vol. 21, p. 66-79Article in journal (Refereed)
    Abstract [en]

    Coastal environments have experienced large ecological changes as a result of human activities over the last 100−200 years. To understand the severity and potential consequences of such changes, paleoenvironmental records provide important contextual information. The Baltic Sea coastal zone is naturally a vulnerable system and subject to significant human-induced impacts. To put the recent environmental degradation in the Baltic coastal zone into a long-term perspective, and to assess the natural and anthropogenic drivers of environmental change, we present sedimentary records covering the last 1000 years obtained from a coastal inlet (Gåsfjärden) and a nearby lake (Lake Storsjön) in Sweden. We investigate the links between a pollen-based land cover reconstruction from Lake Storsjön and paleoenvironmental variables from Gåsfjärden itself, including diatom assemblages,organic carbon (C) and nitrogen (N) contents, stable C and N isotopic ratios, and biogenic silica contents. The Lake Storsjön record shows that regional land use was characterized by small-scale agricultural activity between 900 and 1400 CE, which slightly intensified between 1400 and 1800 CE. Substantial expansion of cropland was observed between 1800 and 1950 CE, before afforestation between 1950 and 2010 CE. From the Gåsfjärden record, prior to 1800 CE, relatively minor changes in the diatom and geochemical proxies were found. The onset of cultural eutrophication in Gåsfjärden can be traced to the 1800s and intensified land use is identified as the main driver. Anthropogenic activities in the 20th century have caused unprecedented ecosystem changes in the coastal inlet, as reflected in the diatom composition and geochemical proxies.

    Baltic Sea Coastal Eutrophication in a Thousand Year Perspective2019In: Frontiers in Environmental Science, ISSN 2296-665X, Vol. 7, article id 88Article in journal (Refereed)
    Abstract [en]

    Sediment cores from three sites along the east-coast of Sweden, north-western Baltic Proper, have been studied with respect to lithologies, geochemistry and diatom assemblages to trace and date early human impact with emphasis on nutrient discharge. The three sites Bråviken, Himmerfjärden and Ådfjärden, have been impacted to various degree during the last millennia by multiple stressors like excessive nutrient discharge and hazardous substances, leading to coastal hypoxia, eutrophication and pollution. These stressors are mainly caused by drivers in the drainage area as increased human population, changed land use and point sources as industries and a sewage treatment plant. Even though their detailed history differs, the results show similar general patterns for all three sites. We find no evidence in our data from the coastal zone supporting the hypothesis that the extensive areal distribution of hypoxia in the open Baltic Sea during the Medieval Climate Anomaly was caused by human impact. Timing of the onset of man-made eutrophication, as identified from d15N and changes in diatom composition, differs between the three sites, reflecting the site specific geography and local environmental histories of these areas. The onset of eutrophication dates to 1800 CE in Bråviken and Himmerfjärden areas, and to 1900 CE in the less urban area of Ådfjärden. We conclude that the recorded environmental changes during the last centuries are unique in a thousand year perspective.

    Kvävehalt i mänskligt urin baserat på kosthållning: Påverkan på tillväxt av grönslick (Cladophora glomerata) samt förekomst av fytoplankton2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Baltic Sea is a brackish water that is severely affected by eutrophication. Anthropogenic (human) nitrogen emissions is a contributing factor leading to algal blooms and hypoxic and anoxic seabeds. Municipal wastewater treatment plants account for 27 percent of the nitrogen emissions into the Baltic Proper. According to an article published by Karlsson-Ottosson in the magazine Ny Teknik and the HAVET 2015/2016 report, the increased meat consumption causes difficulties for the sewage treatment plants to purify the nitrogen in the wastewater. This, according to the article and report mentioned, correlates with increased nitrogen emissions from the municipal wastewater treatment plants. The purpose of this study was to investigate if this observed correlation could be confirmed. This study has measured the nitrogen content of urine from participants (n=36) categorized by diet. The diet categories that was included in this study were meat (K), lacto-ovo vegetarian (LOV) and vegan (V). The daily protein intake from the participants in the categories mentioned above was analyzed in this study. Furthermore, the growth of green algae (Cladophora glomerata) and presence of phytoplankton was investigated by fertilizing the collected samples with urine. The results show that there is no difference in nitrogen content in urine, neither in the protein intake between the three diet categories, nor in the case of presence of phytoplankton. Regarding the growth of the green algae, there was a significant difference between the diet groups of meat (K) and control (KON), and also between meat (K) and people on a vegan diet (V). The green algae therefore grew better in brackish water with urine from people who had a meat (K) diet than it did in brackish water with urine from people who had a vegan (V) diet. Though the growth results showed a significant difference between these diet groups (K and V), the alleged correlation between increasing meat consumption and increasing nitrogen emissions from municipal wastewater treatment plants needs to be further studied.

    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, p. 858-871Article 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.

    Policy Forum: Challenges and opportunities in developing new forest governance systems: Insights from the IPBES assessment for Europe and Central Asia2018In: Forest Policy and Economics, ISSN 1389-9341, E-ISSN 1872-7050, Vol. 97, p. 175-179Article in journal (Refereed)
    Abstract [en]

    Efforts to develop new governance systems in environmental policy at the international, national and subnational level face multiple challenges. In the context of these challenges, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) was established by the United Nations in 2012 to become the leading intergovernmental body for assessing the state of the planet’s biodiversity, its ecosystems, and the essential contributions they provide to society. In this note, we refer to the Regional Assessment for Europe and Central Asia. As co-authors of the report, we present the results of our assessment focusing on the forest sector due to its high potential for conserving biodiversity and providing ecosystem services. Notwithstanding several knowledge gaps, the IPBES regional assessment provides a valuable basis to make better-informed decisions. It identifies promising governance options by mainstreaming the conservation and sustainable use of biodiversity and the sustained provision of ecosystem services into public and private decision making, emphasising a more pro-active and goal-oriented policy approach. To which degree these options can be realized and which pathways will be taken towards a sustainable transition is a matter of societal choice, including policy, economy and citizens.

    Abstract [en]

    In fish aquaculture, great efforts are made to develop feed that excludes marine fish proteins and oils, or at least to decrease these parts to a minimum but the fish might not be attracted to or might not eat the alternative feed. Molecules detected by the olfactory sense can induce arousal and search behavior that attract the fish and induce foraging. In the present study, we have examined whether mussel extracts can induce foraging behavior in crucian carp, Carassius carassius. Free amino acids are present in high concentrations in mussels and they are detected at low concentrations by olfaction and induce food search behavior in several fish species. We studied the behavior responses to water extracts of mussel powder compared to extracts of a plant-based commercial carp feed. Extracts of different concentrations were administered in glass aquaria with individual fish. The tests began with 5 min with only tap water and this was followed by 5 min with extracts or amino acid solutions. The behavior was recorded with a video camera. The initial control period was compared to the following period with odors. No significant foraging response was observed with extracts of mussels, but the commercial carp feed extract induced increased bottom snapping. Synthetic mixtures of five nutritional amino acids present at high concentrations in both extracts did not give any significant foraging response. Our results show that mussels are not suitable as a protein source in feed to crucian carp.

    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.

Lack of plant functional connectivity between isolated populations is often pinpointed as one of the major underlying mechanisms driving subsequent species extinctions. Therefore, landscape-scale conservation management promoting functional connectivity needs to be implemented urgently. Supporting the movement of seed dispersal vectors such as grazing animals may help safeguard local and regional plant diversity in fragmented landscapes. However, the efficacy of such management remains to be thoroughly assessed. Location: Stockholm archipelago, Sweden. Methods: We test how grazing animals may serve as mobile corridors within rotational grazing networks promoting plant functional connectivity via directed seed dispersal. Using landscape genetics, we compare isolated populations of the grassland perennial Campanula rotundifolia located in either active or abandoned grazing networks, to test if spatial patterns in their genetic diversity, differentiation and allele frequencies relate to the presence or absence of connectivity via rotational grazing management. Results: Grazing networks imprinted strong landscape-scale spatial patterning in pairwise population genetic differentiation and within-population genetic diversity. Isolated C. rotundifolia populations functionally connected by grazing animals held higher genetic diversity compared to populations no longer connected by grazing livestock. Gene flow linked to the directed seed dispersal was higher between populations within grazing networks, confirmed by their increased allele richness. We found a predictable, nested loss of genetic diversity among C. rotundifolia populations in abandoned grazing networks. Main conclusions: Grazing animals were important seed dispersal vectors, functionally connecting isolated grassland communities, so being vital to the successful long-term persistence and conservation of not only species but also genetic diversity. Crucially, the study underlines the possibilities of using domestic livestock as mobile corridors within rotational grazing networks as an effective tool to manage, conserve and restore both genetic and species diversity among isolated plant communities in fragmented landscapes.

    Abstract [en]

    Metacommunity theory emphasizes that seed dispersal not only limits but equally maintains plant diversity, though the latter receives little empirical attention. Discerning the temporal and spatial components of seed dispersal and understanding how their interaction shapes fragmented communities and maintains their diversity may be pivotal to further our ecological understanding of spatial and temporal seed dispersal and its implications for landscape-scale conservation management. To investigate the relative importance of spatial and temporal seed dispersal and their roles in maintaining plant diversity, the herb layer and seed bank of grassland communities were inventoried in 77 sites across abandoned and intact rotational grazing networks in a 100 km2 fragmented grassland landscape in the Stockholm archipelago (Baltic Sea, Sweden). Besides analysing alpha- and beta-diversity patterns, nestedness analyses connect deterministic community changes and diversity losses with dispersal-related life-history traits and habitat specialization to identify the mechanism driving community changes and maintaining local diversity. The loss of rotational grazing networks caused community diversity declines via non-random extinctions of spatially and temporally poor dispersers, particularly among grassland specialists. Temporal seed dispersal halted further community disassembly, maintaining diversity in the abandoned grazing networks. Spatial dispersal within the intact grazing networks was found to be an overriding, homogenizing agent conserving diversity in both the herb layer and seed bank. This empirical evidence establishes how spatial and temporal seed dispersal interact to maintain diversity in fragmented landscapes. Poorly connected grasslands appear limited by spatial dispersal, yet are maintained by temporal seed dispersal. In fragmented landscapes where grazing networks are rarely present, temporal rather than spatial seed dispersal may be more important in maintaining species diversity, since effective spatial dispersal may be significantly diminished. The grazing network's efficacy at boosting spatial dispersal and upholding community diversity presents a powerful management tool to conserve local and regional species diversity. © 2017 The Authors
