  1. 1. 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

  2. 2. 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

  3. 3. 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
