The spatial ecology, habitat preference and diet selection of giraffe (Giraffa Camelopardalis Giraffa) in the Kalahari region of South Africa
The research project was conducted within two separate study areas. The main research project was conducted in the Khamab Kalahari Nature Reserve (KKNR) in the North West Province of South Africa. The main research project only commenced after the completion of a preliminary study that was conducted on the Woodland Hills Wildlife Estate in the […]
Feeding behaviour of lions (Panthera leo) on a small reserve
The prey selection and predatory behaviour of a single pride of lions (Panthera leo) was studied in the 8500 ha Karongwe Game Reserve from 1999–2005. The study focused on the difference between prey selection in the first three years when a two-male coalition was present with a similar period thereafter when one of the males […]
Stable carbon isotope reconstruction of ungulate diet changes through the seasonal cycle
We analysed stable carbon isotope ratios (δ13C) in faeces of 11 African ungulate species from three South African savanna environments to determine whether this approach is sufficiently sensitive to record short-term seasonal diet changes in browsers (BR), mixed-feeders (IM), and grazers (GR). At monthly intervals, faecal δ13C revealed variations in proportions of C3 (browse) to […]
Woody vegetation change in response to browsing in Ithala Game Reserve, South Africa
The impact of elephant and other browsers may be magnified when they are restricted within small, fenced reserves. These reserves are becoming commonplace in southern Africa. The composition and structure of the woody vegetation of a portion of the 30 000 ha Ithala Game Reserve, South Africa, was monitored annually from 1992 to 2000. Woody […]
The Ecology and Behaviour of Giraffe in Northern Botswana
Northern Botswana is one of the giraffe strongholds across its geographic range in the absence of, or with low impact from, the major anthropological threats faced elsewhere. Yet despite its conservation significance, until now, no giraffe specific ecological or behavioural studies have been undertaken. Moreover, Africa’s giraffe population has been significantly reduced over the last […]
An Assessment of Forage Selection by Giraffe Introduced into Umfurudzi Park, Northern Zimbabwe
Giraffe (Giraffa camelopardalis) is one of the flagship herbivore species in the savanna ecosystem and is of high conservation value. Management of the species under diversified ecosystems, particularly, their introduction in new ecosystems is of great concern, given that limited information is available of how the species acclimatizes to new ecosystems and which forage species […]
Nightly selection of resting sites and group behavior reveal antipredator strategies in giraffe
This study presents the first findings on nocturnal behavior patterns of wild Angolan giraffe. We characterized their nocturnal behavior and analyzed the influence of ecological factors such as group size, season, and habitat use. Giraffe were observed using night vision systems and thermal imaging cameras on Okapuka Ranch, Namibia. A total of 77 giraffe were […]
Distribution and density of oxpeckers on giraffes in Hwange National Park, Zimbabwe
Oxpeckers (Buphagus sp.) are two bird species closely associated to large mammals, including giraffes (Giraffa camelopardalis). We tested whether oxpeckers distributed themselves at random across individuals or aggregated on individual giraffes, and whether birds select the host’s body parts with the expected greatest amount of ticks. By counting oxpeckers on giraffe’s body from photographs, we […]
Long-term population dynamics of African ungulates in Waterberg Plateau National Park, Namibia
The current study was undertaken to determine long-term population trends (33 years) of ungulate species in the Waterberg National Park (WNP), Namibia, using aerial and waterhole counts of ungulates during the years 1980−2013.We tried to establish how rainfall influences the multi-species population dynamics. During this period sixteen ungulates species were recorded. Among these, eight have […]
Species assignment and conservation genetics of giraffe in the Republic of Malawi
Historically, giraffe have been translocated across Africa to supplement extant populations, reintroduce extinct populations or to establish new populations, often for conservation and tourism. Such faunal relocations were often carried out disregarding taxonomic affiliation. Today, the small giraffe populations in the Republic of Malawi are assumed to consist of South African giraffe (Giraffa giraffa giraffa), […]
