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 …

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
… apex predator currently declining across its African range. Changes in reporting rates from bird atlas surveys suggest declines of up to 60 % over the last 20 years (1987-1982 vs. 2007-2013) across South Africa. Worryingly, large protected areas were not immune to these declines. For instance …

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 …

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 …

Too hot to handle: how Martial Eagles (Polemaetus bellicosus) manage the heat in the Kruger National Park, South Africa
… cameras to remotely monitor nests in the Kruger National Park, where previous studies revealed a large population decline and where temperatures during the breeding season have increased dramatically over the last few decades. We recorded a total of 772 camera trap days (9312 hours) during …

Rivalry for nutrient resources : is there competition below ground between leguminous trees and grasses in a mesic and arid savanna in the Kruger National Park?
… (547 mm MAP) site on clay-rich soils in the Kruger National Park, South Africa. We show that most tree and grass roots are located in the upper layers of the soil and both are present to the bottom of the profile. Root biomass is positively correlated to soil nitrogen and phosphorus and …

A comparative study of rodent and shrew diversity and abundance in and outside the N’washitshumbe enclosure site in the Kruger National Park
… rodent populations in the northern plains of the Kruger National Park and to investigate the possible role they may play as bio-indicators for different management practices. Movement of rodents from one area to the next is expected to be restricted due to changes in the habitat structure. This …

Wire Netting Reduces African Elephant (<i>LOXODONTA AFRICANA</i>) Impact to Selected Large Trees in South Africa
<p>African elephants (<em>Loxodonta africana</em>) are ecosystem engineers in that they substantially alter the environment through their unique foraging and feeding habits. At high densities, elephants potentially have negative impacts on the environment, specifically to large trees. Because of …

Leaf nutrient draw back as a strategy for tree grass co-existence in the savanna biome
… carried out in the sub-tropical savanna biome in southern Kruger National Park, South Africa. Photosynthetic readings show a decrease in leaf activity towards the end of the growing season. There was no significant change in the carbon concentrations over the months for both species sampled but …

Annals of ivory : perspectives on African elephant Loxodonta africana (Blumenbach 1797) feeding ecology from a multi-decadal record.
This thesis explores the dietary responses of African elephants (Loxodonta africana) to environmental change by testing the hypothesis that diet switching (from predominantly browse-based to more grass-rich diets) is driven by cyclical patterns of climate and habitat change in a southern African …

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 …
