The evolution and socio-ecology of two populations of the Vlei Rat, Otomys irroratus.
(1993)
This work investigated two important evolutionary
processes - speciation and adaptive variation - in two
chromosomally-distinct allopatric Natal Midlands populations
of the vlei rat Otomys irroratus. The two populations, ...
Habitat use by ungulates in Thanda Private Game Reserve, KwaZulu-Natal.
(2008)
Knowledge of habitat use and selection is essential to managing ungulate populations. This study assesses habitat use by elephant (Loxodonta Africana), giraffe (Giraffa camelopardalis), kudu (Tragelaphus strepsiceros), ...
Environmental stochasticity and African elephant population dynamics : investigating limitation through juvenile mortality.
(2008)
The successful conservation management of African elephants depends largely on understanding the fundamental processes driving the population regulation of this species. Southern Africa’s increasing populations have raised ...
Metabolic physiology of Colubrid dietary specialists, Dasypeltis scabra and Dasypeltis inornata.
(2009)
Metabolic rate (MR) and digestive duration are thermally dependant, and energy usage changes as body temperature (Tb) changes. Increased Tb during digestion causes a rapid increase in VO2 and a shorter postprandial metabolic ...
Warning vocalisations and predator information transfer in social birds.
(2008)
Alarm or warning vocalizations are produced by many animals when they detect a potential predator. However little is known about the information contained in these vocalizations. This study investigated the warning ...
Bird community ecology and composition in afrotemperate forests of the Drakensberg Mountains, South Africa.
(2009)
Recent research has emphasized the importance of understanding the consequences of species loss, not just for biodiversity per se, but also for ecosystem resilience and functioning. Firstly, a baseline analysis of the ...
Fast life in the slow lane : life history and energetics of a basal placental mammal Setifer setosus (Schreber, 1778).
(2014-08-28)
There is increasing evidence that homeothermy (the maintenance of a high and stable body temperature-Tb) as observed in modern mammals was derived from an ancestral heterothermic (flexible Tb regulation) state. One of main ...
Effect of soil factors on parasitic nematodes of sugarcane in KwaZulu- Natal, South Africa.
(2004)
Nematicides are not only expensive and unaffordable to small-scale farmers but are also harmful to the environment as they kill both the target organisms and non-target micro and macro-organisms, thereby destabilising the ...
The effect of land use on the species composition of amphibians in North Eastern KwaZulu-Natal.
(2010)
Global declines in amphibian species have directed research towards investigating why this is happening. One of the major causes of these declines is the fragmentation and loss of habitat. This study examined the effect ...
Seasonal home range and foraging movements of the Wahlberg's epauletted fruit bat (Epomophorus wahlbergi) in an urban environment.
(2012)
Urbanisation through the process of habitat loss and fragmentation has caused drastic changes in ecosystem dynamics around the world. Many species can no longer survive in these urban areas; however there are those species ...
