  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. SPATIO-TEMPORAL PATTERNS OF THE WOLF AND ITS PREY IN A MEDITERRANEAN AREA

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

    Författare :Giovanni Fini; [2022-08-29]
    Nyckelord :;

    Sammanfattning : Starting from the 1970s, populations of top predators such as the wolf Canis lupushave been expanding across Europe thanks to the protective legislation andthe creation of many protected areas, the increased abundance of wild ungulates and other factors. The return of these animals can trigger significant consequences from the ecological as well as management points of view. LÄS MER

  4. 3. Bats as indicators of habitat connectivity in urban environments

    Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Linnéa Sundberg; [2022]
    Nyckelord :Bats; Sweden; light; fragmentation; connectivity; urban; Myotis; Myotis brandtii;

    Sammanfattning : Human disturbances to natural environments have been an increasing issue since the industrial revolution when the human population started to grow faster than ever before. Habitats have been extensively lost, followed by severe consequences on biodiversity. 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. Sexually segregated habitat selection in Daubenton’s bat Myotis daubentonii

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

    Författare :Esnart Emma Bwalya Chibwe; [2021]
    Nyckelord :sexual segregation; Daubenton’s bat; Myotis daubentonii; landscape analysis; habitat selection; foraging;

    Sammanfattning : Sexual segregation is a phenomenon present in many vertebrate taxa, including the bat order Chiroptera. Sexual segregation is a social and/or habitat separation based on sex and is driven by varying causes such as sexual dimorphism, resource and physiological limitations, predator avoidance and many other factors.
