The numerical status of sixteen game species in the Transvaal, excluding the Kruger National Park
The paper describes the results of a survey to determine the numbers of the following game species in the Transvaal: springbok, blesbok, zebra, blue wildebeest, black wildebeest, red hartebeest, gemsbok, eland, nyaia, buffalo, elephant, giraffe and squarelipped rhinoceros. The distribution of each species is discussed and the different localities of occurrence are illustrated. The growing […]
Diet and seasonal dispersal of extralimital giraffe at Sanbona Wildlife Reserve, Little Karoo, South Africa
South African giraffe (Giraffa camelopardalis giraffa) have been introduced as an extralimital species to private farms in the Little Karoo on the basis of economic sustainability, and the need to create a competitive tourism product. However, little is known about the medium- to long-term impacts and ecological sustainability of such introductions. The diet of a […]
Contemporary niche contraction affects climate change predictions for elephants and giraffes
Aim: Climate change assessments are largely based on correlative species distribution models (SDMs) that are sensible to spatial biases or incompleteness of input distribution data. We tested whether changes on the species’ climatic niche resulting from recent human-induced range contractions have a significant influence on SDM predictions of future species distributions. Location: Africa. Methods: For […]
Giraffa camelopardalis, Giraffe Assessment by: Muller, Z. et al.
Taxonomic Notes: The IUCN SSC Giraffe and Okapi Specialist Group (GOSG) currently recognizes a single species, Giraffa camelopardalis. Nine subspecies of Giraffes are currently recognized (Dagg 2014), although some authorities dispute this taxonomic classification (e.g., Groves and Grubb 2011). Several subpopulations of Giraffe, resident in northern Botswana, northwest Zimbabwe, northeastern Namibia and southwestern Zambia, are […]
Assessment of giraffe populations and conservation status in East Africa
Populations of giraffes Giraffa camelopardalis are declining in the wild, with some populations having suffered an 80% decline in the past ten years. In comparison to other large African mammals, giraffes have been largely overlooked in terms of research attention and conservation action. In recent years, the extent to which giraffe populations have declined across […]
The Giraffe Biology, Ecology, Evolution and Behaviour (Book)
In one form or another, giraffes have been around for a very long time. And so has Homo sapiens. The interaction between giraffes and humans starts way back in prehistory, and rock art (paintings and engravings) is found all over Africa from Morocco, Algeria and Libya in the north, through Ethiopia, Somalia, Kenya and Tanzania […]
The genetics of conservation: Peering into DNA to save species and ecosystems
Scientists know the bear as Ursus americanus kermodei, or the Kermode bear, named after biologist Frank Kermode. Kermode, a former director of the Royal British Columbia Museum in Victoria, was among the first to research the subspecies. The bear is a color polymorphism of the black bear Ursus americanus. “Spirit bears have one of the […]
Genetic diversity in fragmented southern African giraffe populations
The giraffe (Giraffa camelopardalis) is distributed throughout sub-Sahara in savannah habitat. It is currently listed as Vulnerable on the IUCN Red Data List, as their numbers are declining. Little is known about the genetic characteristics of giraffe in South Africa. This molecular analysis of the introduced giraffe populations in the Free State Province thus provides […]
Giraffe south of the Niger-Benue river system
Although giraffes have been seen occasionally south of the Niger river, there is no evidence that permanent populations occur in this area) and presumably the giraffes either die or return to the northern side. The southern habitats may be unsuitable for two reasons. First, human harassment and habitat modification may prevent the establishment of viable […]
The Mammals of Nigeria
Distribution: scattered localities in northern Guinea, Sudan, and Sahel savanna zones; not recorded south of the Niger-Benue rivers in Nigeria (Happold 1969, 1978b) (Map 98). Localities: Benue-Pai river region (Lewis 1955); Chingurme-Duguma GR, Kambari GR (Hall 197 6); Falgoro GR (Henshaw and Child 1972); Lame GR (Hall 1976); Sambisa GR (Hall 1976). Old localities not […]
