  1. 11. Sources of pesticide losses to surface waters and groundwater at field and landscape scales

    Författare :Anna Lindahl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Pesticide residues in groundwater and surface waters may harm aquatic ecosystems and result in a deterioration of drinking water quality. EU legislation and policy emphasize risk management and risk reduction for pesticides to ensure long-term, sustainable use of water across Europe. LÄS MER

  3. 12. Bioavailability of pesticides to benthic invertebrates : the role of aquatic biofilms and humic substances

    Författare :Anna Lundqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In agricultural landscapes, pesticides are frequently contaminating nearby aquatic ecosystems. Unlike most other contaminants, pesticides are targeted against specific organism groups, but will also have negative effects on non-target organisms. When pesticides enter aquatic environments they tend to sorb to fine organic matter. LÄS MER

  5. 14. Biotic resistance in freshwater fish communities

    Författare :Anna Henriksson; Göran Englund; David Wardle A.; Jun Yu; Sebastian Diehl; Donald Jackson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biotic resistance; freshwater fish; introductions; invasions; invasion success; invasibility; invasiveness; species richness; saturation; species identity; weighted species richness;

    Sammanfattning : Invasions of non-native species cause problems in ecosystems worldwide, and despite the extensive effort that has been put into research about invasions, we still lack a good understanding for why some, but not other, communities resist these invasions. In this doctoral thesis I test hypotheses on biotic resistance using a large dataset of more than 1000 both failed and successful introductions of freshwater fish into Swedish lakes. LÄS MER
