  1. 1. Women in the Seascape : Gender, Livelihoods and Management of Coastal and Marine Resources in Zanzibar, East Africa

    Författare :Sara Fröcklin; Maricela de la Torre-Castro; Lars Lindström; Nils Kautsky; Meryl J. Williams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gender; fisheries; invertebrate harvesting; seaweed farming; coastal and marine management; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : All over the world, coastal populations depend on, and influence, the environment in pursue of their livelihoods. Managing the environment, while meeting the growing demand for marine resources, is a challenge. It further requires knowledge about all actors. LÄS MER

  3. 2. Benthic invertebrate food webs in the Baltic Sea : Anthropogenic pressure effects and methodological advancements

    Författare :Julie Garrison; Francisco Nascimento; Ángel Borja; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; food web; trophic network; detritivore; Baltic Sea; macrofauna; marinbiologi; Marine Biology;

    Sammanfattning : Trophic interactions are ecologically important, as they structure communities, and globally important for the ecosystem functions that they facilitate. Anthropogenic pressures are altering the structure of food webs, their stability, and resilience to change. LÄS MER

  4. 3. The importance of biodiversity for ecosystem processes in sediments : experimental examples from the Baltic Sea

    Författare :Johan Näslund; Jonas Gunnarsson; Sara Sjöling; Nils Kautsky; Antoine Grémare; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Soft-bottom sediment; Ecosystem processes; Ecosystem function; Benthic-pelagic coupling; Baltic Sea; Trophic interactions; Pollutant biodegradation; Organic matter mineralization; Deposit feeder; Detritivore; Invasive species; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. LÄS MER

  5. 4. Phenotypic Plasticity and Adaptation Potential to Salinity in Early Life Stages of the Tunicate, Ciona intestinalis spB

    Författare :Elin Renborg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transgenerational acclimation; Environmental variation; Tolerance range; Marine invertebrate; Quantitative genetics; Genetic structure; Local adaptation; Sexual selection; Gamete compatibility; Relatedness; Inbreeding; Heritability; Maternal effects;

    Sammanfattning : Species respond to environmental heterogeneity through a variety of mechanisms such as plasticity, genetic adaptation and phenotypic buffering. Determining how gene flow, scale of environmental heterogeneity and trait heritability influence these responses is important for understanding how these different mechanisms arise, which is a central task in the field of evolutionary biology.

  7. 5. Man-made structures as habitat for marine faunal assemblages

    Författare :Mathias H. Andersson; Sören Nylin; Hans Kautsky; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : Artificial reefs are structures placed in the sea to promote marine life. Although constructions such as oil-rigs, wind farms, bridges and pier pilings are built for other purposes, they could be regarded as artificial reefs as they add new surfaces in the oceans, susceptible to colonization by marine organism.
