  1. 11. Offshore wind farms - ecological effects of noise and habitat alteration on fish

    Författare :Mathias H. Andersson; Sören Nylin; Magnus Wahlberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; renewable energy; fish population; artificial reef; attraction vs. production; habitat structure; reef effect; FAD; bioacoustics; noise disturbance; fish behaviour; detection range; threshold; masking; fish communication and hearing; Marine ecology; Marin ekologi; zoologisk ekologi; Animal Ecology;

    Sammanfattning : There are large gaps in our understanding how fish populations are affected by the anthropogenic noise and the alteration of habitat caused by the construction and operation of offshore wind farms. These issues are of great importance as the construction of offshore wind farms will increase all over the world in the near future. LÄS MER

  3. 12. Fish on drugs : behaviour modifying contaminants in aquatic ecosystems

    Författare :Annelie Lagesson; Jonatan Klaminder; Tomas Brodin; Kathryn Arnold; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aquatic ecosystems; Behavioural effects; Ecotoxicology; Endocrine disruptors; Pharmaceuticals; Interaction effects; ekotoxikologi; Ecotoxicology;

    Sammanfattning : Contamination of surface waters is a worldwide problem. One group of emerging contaminants that reach aquatic ecosystems via sewage treatment plant effluents and agricultural run-offs is pharmaceuticals. LÄS MER

  4. 13. Spatial Modelling of Coastal Fish – Methods and Applications

    Författare :Göran Sundblad; Ulf Bergström; Alfred Sandström; Peter Eklöv; Christian Möllmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; habitat; niche; species distribution modelling; juvenile; fish; larvae; spawning; Marine ecology; Marin ekologi; NATURAL SCIENCES; NATURVETENSKAP; Freshwater ecology; Limnisk ekologi; Biology; Biologi; Biology with specialization in Limnology; Biologi med inriktning mot limnologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Limnologi; Limnology;

    Sammanfattning : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. LÄS MER

  5. 14. Studies of fish responses to the antifoulant medetomidine

    Författare :Anna Lennquist; Göteborgs universitet; []
    Nyckelord :antifouling; fish; medetomidine; ecotoxicology; biomarker;

    Sammanfattning : ABSTRACT Growth of marine organisms, fouling, on man-made constructions submerged in the water is regarded as a major problem. For vessels, fouling increases drag and thereby fuel consumption, wherefore antifouling paints are used. Traditionally, they contain toxic compounds, and several of these have unwanted effects in the environment. LÄS MER

  7. 15. Biochemical characterisation of landfill leachate toxicity in fish

    Författare :Maria Linderoth; Lennart Balk; Ulf Rannug; Cinta Porte Visa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; landfill leachate; endocrine disruption; fish; Environmental toxicology; Miljötoxikologi;

    Sammanfattning : Deposition remains the most common form of waste disposal in many parts of the world. As a terminus of the products consumed in our society a landfill may contain virtually all sorts of man-made chemicals. Despite this, the harmfulness of landfill leachate has not been extensively evaluated in feral organisms in the environment. LÄS MER
