A comparative study of communication in six taxa of southern African elephant-shrews (macroscelididae)
(1996)Aspects of olfactory, auditory, visual and tactile communication were investigated in five Elephantulus species (E. brachyrhynchus, E. edwardii, E. intuft, E. myurus, E. rupestris) and Macroscelides proboscideus, ... -
The conservation ecology of the Nile crocodile (Crocodylus niloticus) at Ndumo Game Reserve in North Eastern KwaZulu-Natal and the Rio Maputo floodplain in South Eastern Mozambique.
(2013)Up until 1969 Nile Crocodiles (Crocodylus niloticus) were considered as vermin in South Africa and were actively persecuted throughout the country. In an effort to re-establish viable populations within protected areas in ... -
Distribution patterns of epigaeic invertebrates across Afromontane forest/grassland ecotones, in KwaZulu-Natal, South Africa.
(2000)Considered key landscape elements, ecotones play an important role in landscape ecology. In heavily fragmented, or heterogeneous landscapes, ecotones become a major, even dominant, feature. Yet, there are relatively few ... -
Dragonfly assemblage dynamics and conservation at small reservoirs in KwaZulu-Natal, South Africa.
(2004)A study of the odonate fauna was carried out at the edge of a major escarpment, in eastern South Africa, using the same methodology as has been used in the temperate regions to obtain a sub-tropical perspective. The study ... -
The dynamics of social relationships among female Chacma baboons (Papio cynocephalus ursinus) in Zululand.
(1993)The focus of this study is the effect of environmental conditions on the social relationships among females in a free-ranging troop of chacma baboons (Papio cynocephalus ursinus), in a southern woodland habitat. The ... -
Ecological studies of bottlenose and humpback dolphins in Maputo Bay, southern Mozambique.
(2008)The ecology and population biology of bottlenose and humpback dolphins inhabiting the Maputo Bay, Southern Mozambique were studied through boat based photoidentification surveys and behavioural methods between December ... -
Ecology and conservation of the Cape vulture in the Eastern Cape Province, South Africa.
(2016)Abstract available in PDF file. -
The ecology and conservation biology of the Black-cheeked Lovebird Agapornis nigrigenis in Zambia.
(2003)This study was undertaken to investigate the ecology of the Black-cheeked Lovebird Agapornis nigrigenis in the wild. Prior to this study little was known about the ecology of this parrot or other members of the genus ... -
The ecology and conservation of blue duiker and red duiker in Natal.
(1990)The ecology of blue duikers Philantomba monticola and red duikers Cephalophus natalensis was studied in three lowland coastal evergreen forests in Natal. Variation in population densities, estimated with numerous census ... -
The ecology of Meyer's parrot (Poicephalus meyeri) in the Okavango Delta, Botswana.
(2008)Meyer’s Parrot Poicephalus meyeri is the smallest of the nine Poicephalus parrots, forming the P. meyeri superspecies complex with five congeners. Their distributional range far exceeds any other African parrot, extending ... -
The ecology, over-wintering and population dynamics of the pre-imaginal stages of the Anopheles gambiae Giles complex (Diptera : culicidae) in northern Natal, South Africa.
(1991)This study investigated aspects of the breeding biology, ecophysiology, morphology, over-wintering and population dynamics of the pre-imaginal stages of members of the Anopheles gambiae complex in northern Natal, South ... -
Ecophysiology and population dynamics of the alien invasive gastropod Tarebia granifera in the iSimangaliso Wetland Park, South Africa.
(2012)Tarebia granifera is a prosobranch freshwater gastropod from south-east Asia which has invaded other sub-tropical parts of the world. This snail has recently also invaded the iSimangaliso Wetland Park, often reaching ... -
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 ... -
Effects of management intervention on elephant behaviour in small, enclosed populations.
(2012)The continual increase in elephant numbers across southern Africa raises concern, though the interventions to manage these populations are more contentious. Within small, enclosed reserves active management is necessary ... -
The effects of sexual dimorphism on the movements and foraging ecology of the African elephant.
(2005)Large herbivores are key components of terrestrial biomes because of their relative abundance and pronounced influence on ecosystem functioning and habitat structure. To manage and conserve these species effectively, ... -
Effects of temperature on members of the Anopheles gambiae complex (Diptera: Culicidae) in South Africa : implications for malaria transmission and control.
(1996)This study investigated the effects of temperature and relative humidity (both controlled and natural) on the lifecyle and morphology of adults of members of the Anopheles gambiae complex in northern KwaZulu-Natal, South ... -
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 ... -
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, ... -
An experimental investigation of the effects of supplementary food and ground cover on small mammal population dynamics and community structure in a Swaziland grassland.
(1997)The primary aim of this study was to investigate the role of food supply and ground cover on the community structure, population dynamics and demography of terrestrial small mammals in a subtropical grassland. This aim ...
