    Sammanfattning : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. LÄS MER

  3. 2. Habitatpreferens hos Anguilla anguilla: makrofyters påverkan på gulålars habitatval under dag och natt

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Nyckelord :European eel; Anguilla anguilla; Yellow eel; Habitat preference; Macrophytes; Substrate; Europeisk ål; Anguilla anguilla; Gulål; Habitatpreferens; Makrofyter; Substrat;

    Sammanfattning : Aquatic vegetation and different substrates can be important factors for fish habitat. The European eel (Anguilla anguilla) is threatened by habitat loss in freshwater systems during its life stage as a yellow eel. To conserve the species, restoration measures and increased knowledge about its preference for benthic habitats are needed. LÄS MER

  4. 3. SWAT Runoff Modeling and Salinity Estimation in the Odra River Catchment

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Tassilo Thebe; [2023]
    Nyckelord :;

    Sammanfattning : In 2022, a significant fish die-off happened in the Odra River due to a bloomof the toxic gold algae species Prymnesium parvum, which occurs in saline andwarm waters. This event is seen as a major ecological disaster in recent Europeanriver incident history. LÄS MER

  5. 4. Microplastics in food webs- occurrence in Lake Vänern brown trout (Salmo trutta) and its main prey

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Hanna Nordström; [2023]
    Nyckelord :microplastic; freshwater; fish; brown trout; mikroplast; sötvatten; fisk; öring;

    Sammanfattning : Over the past decade, research on microplastic pollution has gained significant attention. Research regarding microplastic occurrence in freshwater fish, however is still scarce. While possible pathways have been investigated, passive transfer via ingestion of prey, and possible bioaccumulation in different organs remains relatively unstudied. LÄS MER
