  1. 6. Predatory processes in Baltic benthos

    Författare :Gunilla Ejdung; Susanne Baden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoologisk ekologi; Animal Ecology;

    Sammanfattning : The Baltic soft-bottom community is uniquely simple, with only a few benthic macro-faunal species, and is therefore well suited for mechanistic studies of inter-specific interactions. Two of the dominating organisms in this benthic community are the amphipod Monoporeia affinis and the bivalve Macoma balthica. Field surveys have shown that M. LÄS MER

  3. 7. Exploring the ecotoxicity of microparticle debris

    Författare :Zandra Gerdes; Elena Gorokhova; Martin Ogonowski; Tamara Galloway; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microplastics as emerging pollutants; hazard assessment; ecotoxicological experimental design; aquatic toxicology; chemical vector; suspended solids; reference particles; crustaceans as test organisms; behavioural assays in ecotoxicology; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The global distribution and anticipated increase of environmental microplastic (MP) pollution are concerning. However, while the impacts of macroplastic litter on wildlife are apparent, we know relatively little about the MP hazard potential. LÄS MER

  4. 8. Pharmaecological perspectives : Exposure studies using coastal Baltic Sea organisms

    Författare :Hanna Oskarsson; Linda Kumblad; Ann-Kristin Eriksson Wiklund; Johan Eklöf; Nina Cedergreen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pharmaceuticals; Baltic Sea; Mytilus edulis trossulus; Fucus vesiculosus; Ceramium tenuicorne; Gammarus spp.; Direct effects; Inter-specific interactions; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : This thesis investigates the effects of pharmaceutical substances on coastal Baltic Sea organisms. Despite an increasing awareness of the occurrence of pharmaceuticals in various aquatic compartments, current knowledge of their possible effects on non-target organisms is limited.

  5. 9. The role of sediments in the biogeochemical cycles of nutrients in the Gulf of Riga

    Författare :Juris Aigars; Matti Perttilä; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Sammanfattning : The sediment biogeochemistry of C, N, P and biologic silica (BSi) plays an important role in cycling of these elements in aquatic ecosystems. In shallow coastal and estuarine systems, water-sediment nutrient dynamics can influence biological processes (e.g., primary production) in overlying waters. LÄS MER

  7. 10. Biomarkers for assessing benthic pollution impacts in a subtropical estuary, Mozambique

    Författare :Maria Perpétua Janeiro Scarlet; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; subtrophical estuary; contaminants; biological hierarcial biomarkers; scope for growth; burrowing response; acethylcholinesterase; benthic fauna; southern Mozambique;

    Sammanfattning : This thesis focuses on the marine environment in a subtropical estuary and particularly on exploring a suite of easy-to-use, cost effective and environmentally valid biological response tools (biomarkers). The main driving force of the thesis is the knowledge of the numerous anthropogenic impacts. LÄS MER
