Navigating the night: spatial cognition, locomotor and ranging behaviour in Nycticebus species
… cognitive, and evolutionary factors influence ranging behaviour and spacing in Nycticebus species. I explored these topics with the ultimate goal of informing future conservation actions throughout Southeast Asia, especially translocations and in-situ rehabilitation. Each chapter covers topics, …

Comparative abundance and ranging behaviour of brown hyaena (Parahyaena brunnea) inside and outside protected areas in South Africa
Global biodiversity is declining at an unprecedented rate, principally as a consequence of increasing human population. Effects of this expansion are exemplified by the extent to which many carnivores are now in conflict with humans, particularly in unprotected rangelands. One such species is the …

The movement and landscape use of Blue Cranes in the Western Cape
… the breeding status/season influences their ranging behaviour. There was no significant difference of the home range size between breeding cranes and non-breeding cranes (p > 0.05). There was also no significant difference of the home range size of breeding cranes between their seasons (p > …

Some factors affecting the feeding ecology and socio-biology of the samango monkey, cercopithecus albogularis schwarzi roberts, 1931
… rich food supply, the food resources, feeding behaviour and ranging behaviour of the samango monkey was studied in forest on the Eastern Transvaal Escarpment. The taxonomy of the samango monkey in southern africa is discussed, as well as it•s relationship to other forest Cercopithecines. The …

Understanding the epidemiology of bovine TB and potential routes of infection by elucidation of fine-scale badger behaviour and movement
… areas of high badger density. The movement and behaviour of badgers is central to understanding disease transmission to livestock and will directly influence the efficacy of disease management strategies. This thesis addresses gaps in the current understanding of badger ecology and bTB …

Behavioural ecology and conservation of the Anosy mouse lemur (Microcebus tanost) in the littoral forests of southeastern Madagascar
… widely regarded as an ideal model taxa to study behavioural ecology, sociality and evolution in primates, however relatively few recognised forms have been studied to date. The principal aim of this work is to investigate the behavioural and ecological character of the Anosy mouse lemur …

Uakaris and Amazonian flooded forest.
… of fruits. Several aspects of the ecology and ranging behaviour of the uakaris are associated with the temporal and spatial patterns of distribution of potential food sources: the seeds of immature fruits. Subdividing fruits into separate morphological classes is of fundamental importance for …

Behavioural and physiological responses of chacma baboons (Papio ursinus) to wildfire in the Cape Peninsula of South Africa
… environmental stimuli through physiological and behavioural adjustments. Specifically, primates exhibit a high degree of ecological flexibility, which allows them to persist through environmental changes that vary in duration and predictability. To cope with the variability of conditions within …

Behavioural and isotope ecology of marine-foraging chacma baboons (Papio ursinus) on the Cape Peninsula, South Africa
… zone. There are qualitative descriptions of this behaviour in the literature, but the relative contribution of marine foods to baboon diet, the influence of lunar cycles on exploitation and the impacts of marine foraging on ranging behaviour and activity budgets through different seasons have yet …

How common ravens (Corvus corax) exploit anthropogenic food sources through time and space in a semi-transformed, alpine environment
… sources. The common raven, Corvus corax, is a behaviourally flexible and ecologically adaptable species that has managed to thrive in human transformed landscapes by exploiting these anthropogenic sources of food. The aim of this research was to investigate how raven individuals vary in their …

Habitat use and responses to odours by rodents in New Zealand
… Island by poisoning using Brodifacoum. The ranging behaviour of lethally poisoned radio-carrying rats (n=9) was unaffected by ingestion of poison until shortly before their death when they stopped moving and became unresponsive. Laboratory experiments indicated that kiore might avoid the …

The ecology and conservation of the white-winged nightjar Caprimulgus candicans
In the tradition of previous studies of threatened species, this thesis was undertaken with the aim of improving our understanding of the ecology of the White-winged Nightjar Caprimulgus candicans, and providing the information necessary to facilitate conservation efforts on its behalf. In …

Understanding the decline of Martial Eagles Polemaetus bellicosus in the Kruger National Park, South Africa
