Home-range use, activity, and density of caracal in relation to prey density
- N. Avenant, J. Nel
- Environmental Science
- 1 December 1998
The use by caracal of specific plant communities showed a significant positive correlation to prey biomass of rodents and short-term use of space was related to concurrent availability of prey.
Among habitat variation in prey availability and use by caracal Felis caracal
- N. Avenant, J. Nel
- Environmental Science
- 2002
Results indicate that at any given time or place caracal take a wide range of prey species but concentrate on those that are most abundant, and are thus generalist feeders.
Social organization and movement patterns of Black-backed jackals Canis mesomelas in South Africa*
- J. Ferguson, J. Nel, M. D. Wet

The significance of the division of Black-backed jackal populations into breeding and non-breeding components is discussed as well as the similarities among the social systems of Canis mesomelas.
Diet of the South African large-spotted genetGenetta tigrina (Carnivora, Viverridae) in a coastal dune forest

The results show the South African large-spotted genet to have an opportunistic, generalist food, which correlates with data from other studies.
Scent marking and midden use by aardwolves (Proteles cristatus) in the Namib Desert
- J. Nel, J. P. Bothma

Summary
Aardwolves have two methods of paste marking with anal gland secretion, resulting in minute spots or smears 2–3 mm or more long. These minute spots could aid in the recognition of areas…
Convergence and divergence in prey of sympatric canids and felids: opportunism or phylogenetic constraint?
It is argued that using the O/P distinction allows a better understanding of changes in food niche breadth of particular species, especially in xeric areas, and gives a better indication of possible exploitative competition for food by sympatric carnivores than when regarding all prey taxa as actively pursued.
Diet and foraging group size in the yellow mongoose: a comparison with the suricate and the bat-eared fox
It is argued that phylogenetic inertia, i.e. the inability to better utilize the availability of abundant, clumped prey – such as harvester termites – by resorting to group foraging, can explain the small foraging group size of yellow mongooses.
Comparison of the diet of the yellow mongoose in a coastal and a Karoo area
- N. Avenant, J. Nel
- Environmental Science
- 1992
The presence of other prey types in scats at both study sites indicates opportunistic feeding behaviour by this mongoose, and dietary patterns of yellow mongooses reflect fluctuations in prey availability.
Distribution and habitat choice of Cape clawless otters, in South Africa
Cape clawless otters, Aonyx capensis, are widely distributed in South Africa, as elsewhere on the continent. They occur in a wide variety of environments and most aquatic habitats, from freshwater…
