Scrounging herbivores use both patch quality and dominance status of patch holders when deciding which patch to join.
(2011)One of the major costs of group living is increased competition due to social information. Social information allows foragers to gain information about the location and the quality of food patches from observing other group ... -
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 ... -
Seasonal variation in the thermal biology of the rock hyrax (Procavia capensis)
(2003)Animals in the Southern African sub-region are faced with unpredictable seasonal rainfall patterns and unpredictably low resource availability due to the influence of the El Nino Southern Oscillation System. This has led ... -
Sexual reproduction of Pocillopora damicornis (Cnidaria : hexacorallia) at high latitude off Durban, South Africa.
(2009)Pocillopora damicornis is one of the best-studied and most widespread of corals. Previous studies on its sexual reproduction have yielded a diverse and contradictory view of its reproductive strategy. This coral has long ... -
Sexual selection of multiple ornaments in the red-collared widowbird.
(2001)Although sexual selection often explains the evolution and maintenance of a single male ornament, it is unclear how the multicomponent nature of most sexual displays evolves. Theoretical models suggest that handicap ... -
Spatial and temporal dynamics of freshwater wetlands on the eastern shores of St. Lucia, as reflected by their macrofaunal composition and distribution.
(2004)The wetlands on the Eastern Shores of Lake St Lucia are primarily groundwater fed and exhibit a variety of hydrological regimes that give rise to a high degree of habitat and species diversity. Hydrologically unstable ... -
Spatial utilisation, habitat selection and population status of the wild dog (Lycaon pictus) population in Hluhluwe Umfolozi Park.
(1996)The African wild dog (Lycaon pictus) was reintroduced into Hluhluwe Umfolozi Park (HUP) in 1980/81 after an absence of over 50 years. A 'hands off' management approach was applied. Although the reintroduction is regarded ... -
The status and ecology of the leopard tortoise (Geochelone pardalis) on farmland in the Nama-Karoo.
(2001)The Family Testudinidae (Suborder Cryptodira) is represented by 40 species worldwide and reaches its greatest diversity in southern Africa, where 14 species occur (33%), ten of which are endemic to the subcontinent. ... -
The sustainability of leopard panthera pardus sport hunting in Niassa Reserve, Mozambique.
(2012)Leopard Panthera pardus are an economically valuable asset and when used in sustainable consumptive use programs can provide tangible benefits to communities to improve human livelihoods and the conservation of the species. ... -
Thermoregulation and nocturnal heterothermy in the white-backed mousebird (Colius colius)
(1998)Thermoregulatory patterns, the use of rest-phase heterothermy, the energetic significance of clustering behaviour, and the role of sunning behaviour in thermoregulation were assessed in the white-backed mousebird Colius ... -
Thermoregulation in breeding crowned plovers (Vanellus coronatus)
(2000)Ground-nesting birds nesting in the open have to cope with an extreme thermal environment. Their nests egos and chicks are often located within the boundary layer and are exposed to, direct solar radiation. In preventing ... -
Use of space and activity rhythms of spotted-necked otters in the Natal Drakensberg.
(1995)The study was carried out in Kamberg Nature Reserve (Natal Drakensberg) from June 1994 to August 1995. Seven spotted-necked otters were fitted with an intraperitoneal radio-implant; radio-tracking was performed by both ... -
Utilisation of low density vacuum zones by white rhinos in the Umfolozi Game Reserve.
(1998)White rhinos in the Umfolozi Game Reserve (UGR) are managed with a 'Sink Management Policy' which utilises natural dispersal patterns of white rhinos from an area of high density (the core), to areas of low density (vacuum ... -
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 ... -
Wildlife rehabilitation in South Africa.
(2009)Wildlife rehabilitation, defined as “providing temporary care to injured, ill and orphaned wild animals with the goal of releasing them back into their natural habitat”, developed in response to the increase in human ...
