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. Constructing a food web from inventory data in a boreal forest-dominated national park in south-eastern Sweden

   Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Philip Kjellström; [2023]
   Nyckelord :ecological network; food web; boreal forest food web; national park food web; interspecific competition; swedish forest; construction food web;

   Sammanfattning : A food web was constructed for a boreal-forest dominated national park in south-eastern Sweden, called Tyresta national park and its surrounding nature reserve. Due to increasing threats to mammalian species and their critical role in the food web mammals were used as the outset of the food web, and from there branching out to taxa trophically interacting with mammals directly and indirectly.

4. 3. Differences in velocity between the sexes and stages of courtship in a dance fly

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

   Författare :Filip Myllyaho; [2022-02-17]
   Nyckelord :Dansfluga; Hilara maura; höghastighetskamera; partner-val; Dance fly; Hilara maura; high-speed camera; mate choice;

   Sammanfattning : Dance flies (Diptera: Empididae: Empidinae) are famous for their elaborate mating behaviour, which can be broken down to three distinct stages in adults: hunting, swarming, and mating. In many species, males hunt for prey that they present as nuptial gifts to recipient females in swarms, after which the pair will copulate in the air or after landing on nearby vegetation. LÄS MER

5. 4. Brain morphology and behavioural variation in relation to habitat and predation risk in minnows (Phoxinus phoxinus)

   Master-uppsats, Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Marina Gallego González; [2022]
   Nyckelord :brain size; Ecology; environmental complexity; European minnow; fish; geometric morphometrics; morphological divergence; phenotypic plasticity; schooling.;

   Sammanfattning : So far, research on inter- and intraspecific teleost brain plasticity across different freshwater environments has been widely conducted. However, insights of brain morphological variation on social and predator avoidance behaviours are lacking. LÄS MER

7. 5. Non-naivety in a long-lived ungulate : learning effects of shooting moose calves?

   Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

   Författare :Lukas Graf; [2021]
   Nyckelord :moose; Alces alces; integrated step selection function; habitat selection; anti-predator behavior;

   Sammanfattning : Habitat selection and movement are considered important factors for survival of game species when they are hunted by humans. To reduce their risk of predation, animals can adapt their behavior to their most abundant predator over time through experience. LÄS MER
