    Sammanfattning : The round goby (Neogobius melanostomus) is an invasive alien species that poses one of the greatest threats to biodiversity and ecosystem services in Sweden today. The round goby originates from the Black Sea and Caspian Sea but has in recent decades rapidly spread with global shipping traffic to new areas in Europe and North America. LÄS MER

  3. 2. The Great cormorant, Phalacrocorax carbo, as a predator of the invasive Round goby

    Kandidat-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Louisa Alvarez Blomgren; [2023]
    Nyckelord :Round goby; invasive species; Great cormorant; predator-prey interaction; prey selectivity;

    Sammanfattning : Dispersal of invasive species poses a significant threat to biodiversity loss globally and is one of the major threats to the ecological condition in the Baltic Sea. The Baltic Sea is facing potential problems caused by the Round goby, Neogobius melanostomus, which was presumably introduced via ballast water. LÄS MER

  4. 3. Can cormorants be used as indicators of local fish abundances? : A diet study of cormorants on Gotland

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Oliver Kai Hansen; [2021]
    Nyckelord :cormorants; Baltic; Gotland; human-wildlife conflict;

    Sammanfattning : Human wildlife conflicts can represent missed opportunities for ecological monitoring, including tracking invasive species. The great cormorant Phalacrocorax carbo sinensis is the centre such a conflict, where the lack of concrete scientific evidence is often replaced by anecdotal evidence, leading to the vilification of these birds.
