  1. 21. Effects of morphometric isolation and vegetation on the macroinvertebrate community in shallow Baltic Sea land-uplift bays

    Författare :Joakim Hansen; Lena Kautsky; Erik Bonsdorff; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lagoons; macrofauna; macrophytes; hydrophytes; charophytes; ecological succession; structural complexity; habitat complexity; habitat selection; species composition; biodiversity; stable isotopes; food web; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; Plant Ecology; växtekologi;

    Sammanfattning : Shallow sheltered Baltic Sea bays are ecologically important habitats that harbour a unique vegetation community and constitute vital reproduction areas for many coastal fish species. Knowledge about the invertebrate community in these bays is, however, limited. LÄS MER

  3. 22. The potential of an unmanned aircraft system for surveying lake and river vegetation

    Författare :Eva Husson; Seppo Hellsten; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Landscape Ecology; Landskapsekologi;

    Sammanfattning : Vegetation in and along aquatic systems has important regulatory and ecological functions. Aquatic vegetation is also frequently used as an indicator of environmental conditions. To enhance our knowledge of the complex natural processes in the littoral zone, i.e. LÄS MER

  4. 23. Effects of ozonated sewage effluents and pharmaceuticals in zebrafish (Danio rerio)

    Författare :Johannes Pohl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aquatic environment is the main destination for many organic pollutants originating from human activity. Pharmaceuticals are significant contributors to this pollutant cocktail. LÄS MER

  5. 24. Choosing the best of both worlds : the double life of the great crested newt

    Författare :Daniel Gustafson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The great crested newt (Triturus cristatus) is dependent on two environments for its survival: the aquatic habitat necessary for breeding and development, and the terrestrial habitat required for post-breeding and juvenile activities. For a population to be able to survive in a landscape, both habitat types must be present within migration distance from each other. LÄS MER

  7. 25. On the use of genomics to asses environmental risks of pharmaceuticals

    Författare :Lina-Maria Gunnarsson; Göteborgs universitet; []
    Nyckelord :comparative pharmacology; ecotoxicology; fish; microarray; genomics; wastewater treatment;

    Sammanfattning : Many drugs are found in the aquatic environment and are therefore a cause for concern. Low concentrations of active ingredients from human pharmaceuticals reach the environment via sewage treatment plants, mainly as a result of excretion. LÄS MER
