Movement analysis for monitoring predation by large carnivores : lions in Kruger National Park
… Positioning System (GPS) data from lions in the Kruger National Park (KNP). I develop Generalized Linear Models (GLMs) that increase the probability of locating kills at GPS cluster events. By increasing the predictive ability of detecting kills I show that this technique can be used to locate …

Legitimacy and the Use of Natural Resources in Kruger National Park, South Africa
… case-study of subsistence-based resource use in Kruger National Park, South Africa. The collection of firewood, medicinal plants, thatching grass, and meat by local residents living outside Kruger has long been a contentious issue. Since the Park's establishment in 1926, resource use among local …

Genetic admixture of Kruger National Park black rhino (Diceros bicornis minor): conservation implications
… black rhinoceros Diceros bicornis minor within Kruger National Park (the largest free-ranging population of this subspecies) using nuclear and mitochondrial DNA. I compared the diversity of this founded population with the two source populations (KwaZulu-Natal, South Africa and Zimbabwe) using …

Plant traits and drought tolerance in the savanna : a Kruger National Park case study
… drought tolerance. The study was carried out in Kruger National Park in the month of June. A number of plant traits including wood density, leaf thickness, leaf life span/longevity and water potential were measured along a rainfall gradient (from south to north of the park). Wood density and …

Performance evaluation of photovoltaic and diesel electricity generation applications in the Kruger National Park
… in Southern Africa preclude the extension of the national electricity grid to meet these demands. Traditionally diesel generator sets have been used for off-grid power supply, but the advent of silicon based photovoltaic technology has introduced PV systems as an elegant and increasingly cost …

Spatio-temporal change in riparian woodlands of the Kruger National Park: drivers and implications
… a loss of large trees along the rivers of the Kruger National Park (KNP) over the last century. These habitats occupy a tiny fraction of the park’s surface area but fulfil critical ecological functions and provide several ecosystem services. Little research has, however, focused on riparian …

Pansteatitis in African sharptooth catfish, Clarias gariepinus (Burchell), in the Kruger National Park, South Africa
In the Kruger National Park (KNP), pansteatitis in sharptooth catfish, Clarias gariepinus (Burchell), was shown to be a serious problem in the inlets to large man-made lakes fed by rivers arising in the polluted catchments of the Olifants and Sabie rivers. An increasing prevalence of pansteatitis …

Understanding the decline of Martial Eagles Polemaetus bellicosus in the Kruger National Park, South Africa
… these declines. For instance reporting rates in Kruger National Park (KNP; ca. 20,000 km²), an area often considered a stronghold for Martial Eagles, recorded a 54 % decline in reporting rates. It is not clear what the major drivers of declines have been in South Africa, nor what is contributing …

Investigating the effects of environmental variables on martial eagle breeding performance in the Kruger National Park
… Similar declines have also been reported within Kruger National Park (KNP), which is regarded as a stronghold for this species. Declines within KNP have been attributed to the low productivity rates. As apex predators, marital eagles are considered to be good indicators of ecosystem health, being …

The neo-liberalisation of nature : contextualising the resolution of land claims in the Kruger National Park
… more especially the land restitution in the Kruger National Park re-defined the relationship between nature and society. However, such redefinition of nature and society takes place at the confluence of neo-liberalisation of nature and neoliberal land reform. The thesis provides insight into …

Water and available nitrogen as co-determinants of a mesic savanna in Kruger National Park, South Africa
Savanna is a summer rainfall, tropical and subtropical vegetation type with a continuous grass cover and discontinuous cover of trees. Rainfall plays an important role in savanna as it triggers many ecosystem processes such as nitrogen mineralization. This rainfall is however extremely variable …

An isotope comparison of elephant (Loxodonta africana) diets in the Kruger National Park and Welgevonden Game Reserve
The diet of African elephants (Loxodonta africana (Blumenbach, 1797)) living in savanna environments is unresolved. Elephants are known to include varying proportions of grass and browse into their diet, but there is uncertainty as to whether they are primarily grazers or browsers. This has …

Small mammal community structure (Rodentia: Muridae) in Punda Maria, Kruger National Park, South Africa : Causes and consequences
… of small mammal populations in Punda Maria, Kruger National Park, South Africa was investigated with respect to community size and structure, seed predation and dispersal of several trees. Species populations, community structure and habitat attributes were measured at six sites comprising of …

Long-term effects of fire on nitrogen cycling in a broad-leaf savanna, Kruger National Park, South Africa
… conditions. However, previous research in the Kruger National Park (KNP) and elsewhere found conflicting results for the effects of fire on nitrogen pools and transformation rates. The main aim of this study was to gain a better understanding ofthe long-term effects of fire on nitrogen cycling …

Modeling population dynamics of rhino-poacher interaction across South Africa and the Kruger National Park using ordinary differential equations
… system in both South Africa (SA) and the Kruger National Park (KNP). The data used in this thesis consists mainly of government and police reports, as well publications from several NGOs and the limitations caused by this lack of applicable data are explored. The system dynamics are based …
