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 miljövetenskapSammanfattning : 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
2. The Great cormorant, Phalacrocorax carbo, as a predator of the invasive Round goby
Kandidat-uppsats, SLU/Dept. Of Aquatic ResourcesSammanfattning : 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
3. Top - down control: parasitism and predation on Gonyostomum semen in Swedish brown water lakes
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : 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
4. Invasive round goby, Neogobius melanostomus - suitable prey for native cod, Gadus morhua?
Kandidat-uppsats, SLU/Dept. Of Aquatic ResourcesSammanfattning : 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
5. Geometrical and Evolutionary effects in a Predator-Prey System
Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknikSammanfattning : 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
