Social preferences of translocated giraffes (Giraffa camelopardalis giraffa) in Senegal: Evidence for friendship among females?
Giraffe social behaviour and relationships are currently in the period of scientific renaissance, changing the former ideas of nonexisting social bonds into understanding of complex social structures of giraffe herds. Different giraffe subspecies have been studied in the wild and only one was subject of detailed study in captivity. Our study focused on the neglected […]
Conservation genetics of an isolated giraffe population in Swaziland
Giraffe (Giraffa camelopardalis) are a critical component of the savannah’s browsing guild (Birkett, 2002), although their distribution is discontinuous and the species has declined over most of the range (Fennessy, 2008). Often confined to protected areas, management of the giraffes has increasingly focused on maintaining small, closed populations including private lands or conservation areas (Brenneman […]
The status of and trade in the South African population of giraffa camelopardalis giraffa (South African giraffe)
The South African population of Giraffa camelopardalis giraffa is estimated at between 21,053 and 26,919 individuals, of which between 11,411 and 14,860 individuals occur within national and provincial nature reserves. The species is listed as Least Concern in the IUCN Regional Red List, the national population is well managed and increasing, and the species is […]
Serum concentrations of amino acids, fatty acids, lipoproteins, vitamins A and E, and minerals in apparently healthy, free-ranging Southern Giraffe (Giraffa camelopardalis giraffe)
This pilot project began establishing a nutritional profile for free-ranging giraffe. The results will be used as a tool to begin assessing the nutritional status of captive giraffe. In October 2004 serum samples were collected opportunistically from seven adult and 17 sub-adult giraffe being anesthetized for different studies. Seventeen animals were from Double Drift Game […]
Natural history miscellany winning by a neck: Tall giraffes avoid competing with shorter browsers
With their vertically elongated body form, giraffes generally feed above the level of other browsers within the savanna browsing guild, despite having access to foliage at lower levels. They ingest more leaf mass per bite when foraging high in the tree, perhaps because smaller, more selective browsers deplete shoots at lower levels or because trees […]
Interspecific interference competition at the resource patch scale: do large herbivores spatially avoid elephants while accessing water?
1. Animals may anticipate and try to avoid, at some costs, physical encounters with other competitors. This may ultimately impact their foraging distribution and intake rates. Such cryptic interference competition is difficult to measure in the field, and extremely little is known at the interspecific level. 2. We tested the hypothesis that smaller species avoid […]
Zebra reduce predation risk in mixed-species herds by eavesdropping on cues from giraffe
Predation risk of individuals moving in multispecies herds may be lower due to the heightened ability of the different species to detect predators (i.e., mixed-species effect). The giraffe is the tallest land mammal, maintains high vigilance levels, and has good eyesight. As a result, heterospecific herd members could reduce their predation risk if they keyed […]
Effects of the safari hunting tourism ban on rural livelihoods and wildlife conservation in Northern Botswana
This paper examines the effects of the safari hunting ban of 2014 on rural livelihoods and wildlife conservation in Northern Botswana using the social exchange theory. The paper used both primary and secondary data sources. Data were analysed qualitatively. Results indicate that the ban led to a reduction of tourism benefits to local communities such […]
The relationship between physical injury, body condition and stress-related hormone concentrations in freeranging giraffes
A physiological stress response can be triggered by a variety of intrinsic and extrinsic stimuli, but minimal information is available about the physiological stress response related to pain in wildlife. Recently established techniques now allow the non-invasive measurement of faecal glucocorticoid metabolite (fGCM) concentrations to monitor the physiological stress response in giraffe. We examined the […]
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 […]
