1. 1. Influence of surface water availability on the distribution of White Rhinoceros in central Greater Kruger

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

   Författare :Julie Mauguiere; [2022]
   Nyckelord :White Rhinoceros; Ceratotherium simum; water provisioning; artificial water; ecological processes; habitat selection; spatial ecology; landscape use; KNP; APNR; SAWC;

   Sammanfattning : The population of white rhinoceros (Ceratotherium simum simum) is now declining in the Kruger National Park (KNP) in South Africa due to the intense poaching crisis ongoing since the early 2000s. The need for an efficient conservation effort has never been greater and requires a better understanding of white rhinoceros distribution in the landscape. 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. Anti-predatory responses of White rhinoceros (Ceratotherium simum) to simulated risk. Does poaching create a landscape of fear?

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

   Författare :Daniel Gambra Caravantes; [2020]
   Nyckelord :white rhinoceros; poaching; playback experiment; anti-predatory behaviour; landscape of fear; perceived predation risk;

   Sammanfattning : Predators affect prey’s behaviour which can lead preys to change their spatial use of the habitat, creating a landscape of fear. This is not generally the case for white rhinoceros (Ceratotherium simum), which as megaherbivores (... LÄS MER

5. 4. 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

7. 5. Nutrient distribution by mammalian herbivores in Hluhluwe-Imfolozi Park (South Africa)

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

   Författare :Laura van Veenhuisen; [2018]
   Nyckelord :megaherbivores; nutrient distribution; stoichiometry; South Africa; Hluhluwe–Imfolozi Park; African savannah; herbivores; wildlife ecology; dung;

   Sammanfattning : African megaherbivores are ecosystem engineers, which are under threat of extinction caused by, among others, poaching and climate change. Their current rates of loss means that there’s a need to better analyse their impact on the environment, in order to predict the consequences of losing this group. LÄS MER
