2. Top - down control: parasitism and predation on Gonyostomum semen in Swedish brown water lakes
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : 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. READ MORE

3. Diversification of predators in multi-trophic communities: A trait-based theoretical approach
University essay from Lunds universitet/Examensarbeten i bioinformatikAbstract : One of the main challenges in ecology and evolutionary biology is to understand how biodiversity emerges and is maintained, given the complexity of ecological and evolutionary processes combined. Understanding how multi-trophic interactions occur from a theoretical perspective is highly relevant for our understanding of diversification in complex ecosystems. READ MORE

4. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Context: A major effect of climatic change is the global increase in forest fires, which potentially creates an increase in food availability for herbivorous species. Also vegetation density and the numbers of tree logs increase in burned sites, and this is thought to influence the perceived risk of herbivore prey species, which affects their anti‐predator behaviour and thereby the patch utilization.

University essay from SLU/Dept. of EcologyAbstract : Carnivores are coming back to Europe and the repercussions of their return on prey species is not fully understood. Research from North American studies suggests predators can indirectly affect how ungulates will select their habitat which can result in a change in vegetation growth as browsing pressure is relaxed in risky areas.
