(University of Pretoria, 2017)Human population growth generally causes carnivore declines. The rapid expansion of urban landscapes creates both biotic and abiotic changes that are known to negatively impact carnivore populations (Šálek, Drahníková & ...
-
(University of Pretoria, 2013)Mating systems are classifications of the outcome of individual strategies aimed at maximising reproductive success. These systems have two components; one describes how individuals socially relate and bond to mating ...

(University of Pretoria, 2011-06-02)In group living species animals commonly compete for limited resources such as food (Darwin 1859). Winning competition for food may be beneficial for an individuals survival or reproductive success (Williams 1966; Clutton-Brock ...

Describing and understanding host-pathogen community interaction at the wildlife/domestic interface (University of Pretoria, 2011)In this thesis, I investigated the relationship between host and pathogen in multi-host and multi-pathogen systems at the interface between wildlife and domestic species. The term “epidemiological interaction” was central ...

(University of Pretoria, 2009-10-29)As a contribution to the existing knowledge of grooming in primates five and a half years of grooming data were examined from a group of free-living chimpanzees (Pan troglodytes) in the Budongo Forest, Uganda, to investigate ...

(University of Pretoria, 2013-07)The diet of an animal plays a fundamental role in its ecology, and the consequence of a specific diet may be more pronounced in mammals with a specialised diet that are more reliant on a specific food type. This can have ...

(University of Pretoria, 2010-09-09)Methods used to estimate the prey consumption by large carnivores include direct continuous observation, stomach content analysis, carcass observations and scat analysis. Continual observations are widely considered the ...
-
(University of Pretoria, 2012-11-09)Small populations of animals are vulnerable to the consequences of breeding within a closed group – inbreeding depression and genetic drift lead to reductions in genetic variability, which in turn can give rise to the ...
-
(University of Pretoria, 2012-10-11)Group size affects individual and collective vigilance levels of prey species. As individual vigilance decreases with increasing group size, the indirect risk of predation to each individual and the group as a whole will ...
