The behaviour and dietary preferences of southern giraffe (giraffa camelopardalis giraffa) on the umphafa private nature reserve, kwa-zulu natal
The giraffe (Giraffa camelopardalis) has been severely neglected among the scientific community in terms of research. This investigation explores their behavioural patterns with focus on feeding behaviours and dietary preferences under influencing factors, which provides vital information for conservation in situ and population management ex situ. The behaviour and dietary composition of nine Southern Giraffe […]
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 […]
Examining disease prevalence for species of conservation concern using non-invasive spatial capture–recapture techniques
on‐invasive techniques have long been used to estimate wildlife population abundance and density. However, recent technological breakthroughs have facilitated non‐invasive estimation of the proportion of animal populations with certain diseases. Giraffes Giraffa camelopardalis are increasingly becoming recognized as a species of conservation concern with decreasing population trajectories across their range in Africa. Diseases may be an […]
How a Tiny Worm is Irritating the Most Majestic of Giraffes
What is a fly to a giraffe? It’s difficult to imagine a single insect even coming to the attention of these peculiar animals, which weigh in at thousands of pounds and routinely stretch their necks to heights of more than 14 feet. In Uganda’s Murchison Falls National Park, however, Michael B. Brown, a wildlife conservation […]
Computer-aided photographic pelage pattern analysis of Giraffa camelopardalis (Artiodactyla: Giraffidae)
The giraffe (Giraffa camelopardalis) is one of the most recognisable animal species on earth. Yet hunting and habitat loss and fragmentation have led to severe, but until recently largely unnoticed, declines of giraffe populations all over Africa. The IUCN recognised one single species with nine subspecies and changed the status from ‘Least Concern’ to ‘Vulnerable’ […]
How many species of giraffe are there?
In a recent paper in Current Biology, Fennessy and colleagues [1] conclude that there are four species of giraffe and that their numbers are declining in Africa. Giraffes (Giraffa camelopardalis) are presently classifi ed as one species, with nine subspecies, which are considered ‘Vulnerable’ on the IUCN Red List [2]. The present consensus of one […]
Preliminary Report on Forage Availability and Resource Use by Reticulated Giraffe at Mugie Conservancy, Laikipia, Kenya
Main Findings To compare resource availability and animal diets, we conducted vegetation surveys and collected giraffe dung samples for diet analyses on the east and west sides of primary road C77 at Mugie Conservancy. The availability of tree resources differed on the east versus west sides of C77, where the more abundant species that we […]
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 […]
The running kinematics of free-roaming giraffes, measured using a low cost unmanned aerial vehicle (UAV)
The study of animal locomotion can be logistically challenging, especially in the case of large or unhandleable animals in uncontrolled environments. Here we demonstrate the utility of a low cost unmanned aerial vehicle (UAV) in measuring two-dimensional running kinematics from free-roaming giraffes (Giraffa camelopardalis giraffa) in the Free State Province, South Africa. We collected 120 […]
Interspecific and temporal variation of condensed tannins and cyanide concentrations in potential dietary sources of extralimital giraffes (Giraffa camelopardalis) in the Karoo
During 2016 and 2018 four giraffe (Giraffa camelopardalis) mortalities occurred in the Karoo potentially caused by acute hydrogen cyanide poisoning. Plants have various defence mechanisms to protect themselves against herbivory, including the production of secondary metabolites such as condensed tannins and hydrogen cyanide. This study quantified condensed tannin and hydrogen cyanide production in selected Karoo […]
