  1. 1. African elephants' effect on the temporal use of elephant highway by predator and prey. Makgadikgadi Pans National Park.

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Rebecka Relfsson; [2023-08-18]
    Nyckelord :African savanna elephant; elephant highways; interspecies interactions; predation avoidance; predator-prey interaction; temporal activity;

    Sammanfattning : African savanna elephants (Loxondonta africana) are the world’s largest land-mammal and are considered a keystone species. The effect they have on vegetation and their environment is well known, but their effect on other animal species is less studied. 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. Top - down control: parasitism and predation on Gonyostomum semen in Swedish brown water lakes

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Ingrid Bergman; [2022]
    Nyckelord :limnology; phytoplankton; top-down control;

    Sammanfattning : Gonyostomum semen is a raphidophyte microalgae that can be found in brown water lakes all over Sweden. The species forms substantial summer blooms that can completely dominate the phytoplankton community, largely due to its limited grazing pressure. To test whether parasites control the abundance of G. LÄS MER

  5. 4. Invasive round goby, Neogobius melanostomus - suitable prey for native cod, Gadus morhua?

    Kandidat-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Andreas Ljung; [2020]
    Nyckelord :Round goby; invasive species; cod; predator-prey inter-action;

    Sammanfattning : Invasive species is a worldwide issue that is considered to be the one of the main reasons to losses of biodiversity. The round goby, Neogobius melanostomus, is an invasive species in the Baltic Sea that originates from the Black- and Caspian Sea. LÄS MER

  7. 5. Geometrical and Evolutionary effects in a Predator-Prey System

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Loanne Berggren; Albin Bramstång; Henrik Ernstsson; Hanna Kowalska Elleberg; Erik Ramqvist; Sebastian Ånerud; [2014-10-02]
    Nyckelord :;

    Sammanfattning : The area of investigation is the dynamics of a predator-prey relationship. To model the relationship, an agent based model is used as a base for a simulation tool. LÄS MER
