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. Elephants and aboveground carbon stocks in a South African protected savanna

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

   Författare :Camille Cheyenne Schröcker; [2022]
   Nyckelord :above-ground carbon stocks; climate change mitigation; elephant impacts; megaherbivores; conservation; wood density;

   Sammanfattning : Savanna elephants (Loxodonta africana) are known to exert transforming impacts on the vegetation. Due to these impacts, one would expect elephants to have significant effects on aboveground carbon stocks. However, we still know relatively little about the magnitude and direction of the effects of elephants on aboveground carbon stocks. LÄS MER

4. 3. Spatial and temporal variability in grassland structure associated with different densities of the white rhinoceros (Ceratotherium simum) in a South African savanna

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

   Författare :Emilia Malmström; [2019]
   Nyckelord :white rhinoceros; african savanna; keystone species; herbivory; cascading effects; poaching;

   Sammanfattning : The direct and indirect relationships between species in different trophic levels are referred to as trophic dynamics and are important in maintaining the function of ecosystems. Megaherbivores may have effects both directly and indirectly on other species since their impact may be disproportionately large relative to their population size. LÄS MER

5. 4. The elephant in the room - use of enclosure and activity budget of a group of African savanna elephants (Loxodonta africana) in a Swedish zoo

   Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

   Författare :Maria Grüneberger; [2018]
   Nyckelord :African elephant; behaviour; activity budget; use of enclosure; novel environment; animal management; Loxodonta africana; zoological institution; Scandinavia;

   Sammanfattning : African elephants ( Loxodonta africana ) are social animals that are adapted to life in arid environments. Zoos in northern climates have to keep elephants confined indoors for several months a year due to the risk of cooling down body core temperature and slipping on frozen ground. LÄS MER

7. 5. Grazing impacts on savanna vegetation states and its role in albedo changes

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

   Författare :Joana Fernandes; [2018]
   Nyckelord :albedo; grazing; grazing lawn; white rhino; shrub encroachment; Hluhluwe-iMfolozi;

   Sammanfattning : Albedo, i.e., the fraction of the incoming sunlight that a surface reflects, has been previously shown to play a key role on the climate system by influencing the energy balance of the Earth’s ecosystems. LÄS MER
