  1. 1. Aquatic organisms on the pill - effects on different organizational levels

    Författare :Per Hallgren; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EDC; EE2; 17α-ethinylestradiol; fish; zooplankton; gastropods; population growth rates; direct and indirect effects; somatic growth; invertebrates;

    Sammanfattning : Communities are composed of organisms that interact with each other and with the non-biological environment. There are also anthropogenic pollutants in the environment that also interact with the organisms. LÄS MER

  3. 2. Climate change effects on marine species across trophic levels

    Författare :Nan Hu; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; trophic levels; predation; gastropods; mussels; ocean acidification; ocean warming; interactive effects; interaction types; meta-analysis;

    Sammanfattning : Climate change and anthropogenic activities are producing a range of new selection pressures, both abiotic and biotic, on marine organisms. While there are numerous studies that have investigated the response of individual marine organisms to climate change, few studies have focused on differences in organismal responses across trophic levels.

  4. 3. Estrogen receptor and multixenobiotic resistance genes in freshwater fish and snails: identification and expression analysis after pharmaceutical exposure

    Författare :Cecilia Hultin; Miljövetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EE2; NSAID; estrogen receptor; oestrogen receptor; multixenobiotic resistance; fish; gastropods;

    Sammanfattning : Pharmaceuticals are today released into aquatic environments where they can interfere with organisms' biological processes.The general research objective was to analyze how aquatic freshwater organisms are affected by exposure to pharmaceuticals that are categorized by the EU as potential risk factors to the environment (i.e. LÄS MER

  5. 4. Functional Morphology of Gastropods and Bivalves

    Författare :Jenny Sälgeback; Lars Holmer; John S. Peel; Jan-Ove Ebbestad; Enrico Savazzi; Anders Warén; Uppsala universitet; []
    Nyckelord :Earth sciences; Gastropoda; Bivalvia; functional morphology; constructional morphology; Geovetenskap;

    Sammanfattning : Functional morphology analyzes the relationships between form and function in organisms. However, a comprehensive analysis of any organic structure requires an integrated approach to morphology. For this purpose constructional morphology was developed, where function, phylogeny and construction together explain form. LÄS MER
