The influences of plant secondary metabolites on the foraging behaviour and carrying capacities of the african elephant, loxodonta africana.
Herbivore diet selection is influenced by plant quality and availability. For browsing and mixed-feeding herbivores, such as elephants, which consume trees and shrubs, plant quality is influenced by the concentrations of ...
Olfactory communication of the white rhinoceros (Ceratotherium simum)
Many mammal species communicate olfactorily via specialised scent glandular secretions, urine and/or dung. Despite a large body of work on olfactory communication, the extent to which mammals communicate via dung odours, ...
Movement, home range and habitat use in leopard tortoises (Stigmochelys pardalis) on commercial farmland in the semi-arid Karoo.
Given the ever-increasing demand for resources due to an increasing human population, vast ranges of natural areas have undergone land use change, either due to urbanisation or production and exploitation of resources. In ...
Assessing the success of red-billed oxpecker translocations as a conservation tool in KwaZulu-Natal, South Africa.
There are numerous factors that contribute to a bird species becoming threatened and in need of increased conservation efforts in order to survive. Compared with fossil records, current extinction rates are much higher ...
The competitive effect of vetiver grass on native grasses and implications for grassland rehabilitation in South Africa.

Understanding the effects of changing climate and land use on woody plant encroachment in South African grasslands and savannas.
The increase in dominance of woody species, observed in many grasslands and savannas worldwide, highlights the sensitivity of woody herbaceous biomass ratios to changed environmental conditions. While the major factors ...
Niche requirements and breeding system of Hypericum pseudohenryi, an invasive plant species in South Africa.
Invasive alien species threaten ecosystems throughout South Africa through alteration of the habitat and loss of biodiversity. Emerging invasive alien plants are those that have small populations, but have the potential ...
A biogeographic study of the KwaZulu-Natal sandstone sourveld patches within the eThekwini Municipal Area.
KwaZulu-Natal Sandstone Sourveld (KZNSS) is an endangered vegetation type in South Africa. Approximately 68% of KZNSS is transformed, with remaining patches existing within an urban and suburban matrix. Fragmented patches ...
