چکیده

At present, a single viable population of endangered African wild dogs occurs in South Africa, in the Kruger National Park. Current conservation efforts focus on reintroducing wild dogs into a series of fenced reserves, thereby creating a meta-population in which sub-populations are actively managed to conserve genetic diversity. Additional options exist for conserving wild dogs outside protected areas. We report on an attempt to assess the numbers of wild dogs remaining outside protected areas as a precursor for conservation planning and show that they form a more significant component of the national population than previously recognized. Total numbers outside protected areas in South Africa are estimated to have fluctuated between 42 and 106 animals during the period 1996–2002. Of these, 25–67 individuals were thought to be resident outside protected areas during this period, with an extent of occurrence of 43 310 km and an area of occupancy of 17 907 km. Sightings were most frequently reported from the western border of Kruger National Park, the Limpopo Valley, and northern KwaZulu-Natal. Most wild dogs occur on game ranches with unmodified land cover and low human densities, close to source populations. Significant scope for distribution expansion exists in the Limpopo and North West Provinces. However, efforts aimed at changing landowner attitudes towards wild dogs are necessary to improve the conservation status of the species outside protected areas.

Genetic analysis shows low levels of hybridization between African wildcats (Felis silvestris lybica) and domestic cats (F. s. catus) in South Africa

Hybridization between domestic and wild animals is a major concern for biodiversity conservation, and as habitats become increasingly fragmented, conserving biodiversity at all levels, including genetic, becomes increasingly important. Except for tropical forests and true deserts, African wildcats occur across the African continent; however, almost no work has been carried out to assess its gen...

Foraging Ranges of Immature African White-Backed Vultures (Gyps africanus) and Their Use of Protected Areas in Southern Africa

Vultures in the Gyps genus are declining globally. Multiple threats related to human activity have caused widespread declines of vulture populations in Africa, especially outside protected areas. Addressing such threats requires the estimation of foraging ranges yet such estimates are lacking, even for widespread (but declining) species such as the African white-backed vulture (Gyps africanus)....

Space Use of African Wild Dogs in Relation to Other Large Carnivores

Interaction among species through competition is a principle process structuring ecological communities, affecting behavior, distribution, and ultimately the population dynamics of species. High competition among large African carnivores, associated with extensive diet overlap, manifests in interactions between subordinate African wild dogs (Lycaon pictus) and dominant lions (Panthera leo) and ...

Tracking data from nine free-roaming Cheetahs (Acinonyx jubatus) collared in the Thabazimbi area, Limpopo Province, South Africa

BACKGROUND In partnership with the University of Pretoria, the Endangered Wildlife Trust's Carnivore Conservation Programme collared six male and three female free-roaming Cheetahs (Acinonyx jubatus) in the Thabazimbi area in Limpopo Province, South Africa. This study was undertaken to determine the spatial ecology of free-roaming Cheetahs that occur outside of formal protected areas on private...

African Wild Dogs (lycaon Pictus) Can Subsist on Small Prey: Implications for Conservation

In mammalian predators, prey size typically increases with body size, such that most carnivores weighing .21.5 kg specialize on prey weighing 45% of their own mass. By hunting in packs, endangered African wild dogs (Lycaon pictus) are able to feed primarily on ungulates weighing .100% of their own individual mass and, in most populations, wild dogs specialize on such large prey. However, we sho...
