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. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : 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.

3. Are birds in agricultural habitats attracted to plant volatiles?
Magister-uppsats, SLU/Dept. of EcologySammanfattning : Birds’ ability to fly allows them to track resource abundance and relocate themselves to areas with more resources. It has been a longstanding belief that they forage mainly through visual cues due to their relatively small olfactory bulbs. LÄS MER
4. The secret role of elephants : mediators of habitat scale and within-habitat scale predation risk
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Elephants have long been recognized as important mediators of savannah vegetation structure. With their activities, like feeding on woody plants they may increase visibility of a habitat and produce coarse woody debris within that habitat. LÄS MER
