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 […]

Matrilineal population structure and distribution of the Angolan giraffe the Namib desert and beyond

The distribution maps of giraffe (Giraffa) subspecies in southern Africa are based on historical assumptions, yet some populations have likely been misidentified, hindering effective conservation efforts. Particularly, the populations in Zimbabwe are poorly studied, and translocations, such as the 1991 movement of giraffe from Namibia’s Etosha National Park to mitigate the human-induced decline of Namibia’s […]

Giraffe translocations: A review and discussion of considerations

Giraffe populations have declined dramatically in the last three decades. Giraffe translocations are likely to increase as wildlife managers seek to augment or re-establish populations. Currently, formal practical guidance for giraffe translocations is limited. Here, we present a review of translocation guidelines emphasising planning, implementation, monitoring and evaluation, and we review giraffe behaviour and ecology […]

Movements and source–sink dynamics of a Masai giraffe metapopulation

Spatial variation in habitat quality and anthropogenic factors, as well as social structure, can lead to spatially structured populations of animals. Demographic approaches can be used to improve our understanding of the dynamics of spatially structured populations and help identify subpopulations critical for the long-term persistence of regional metapopulations. We provide a regional metapopulation analysis […]

Fission–fusion dynamics of a megaherbivore are driven by ecological, anthropogenic, temporal, and social factors

Fission–fusion dynamics hypothetically enable animals to exploit dispersed and ephemeral food resources while minimizing predation risk. Disentangling factors affecting group size and composition of fission–fusion species facilitates their management and conservation. We used a 6-year data set of 2888 group formations of Masai giraffes in Tanzania to investigate determinants of social group size and structure. […]

Evaluating Population Persistence of Censused and Unmanaged Herbivore Populations from the Kruger National Park, South Africa

The application of the Dennis et al. (Ecol. Monogr., 61, 1991) model to data from 12 herbivore populations from the Kruger National Park, South Africa, introduces “risk assessment’ procedures into the conservation management of free-ranging species. The model enables one to predict the probability of reaching an arbitrarily defined threshold population size using census figures […]

Standing Tall for Giraffes – Research and Conservation of an Overlooked African Icon

Despite being iconically African, the giraffe remains largely understudied in the wild—unlike most of the continent’s other large megafauna. In part, this is because giraffes were not heavily hunted until recently: they don’t produce tusks or horns that are coveted as trophies or medicine and they are not an aggressive species. Sadly, the Giraffe Conservation […]

Prey preferences of the cheetah (Acinonyx jubatus) (Felidae: Carnivora): morphological limitations or the need to capture rapidly consumable prey before kleptoparasites arrive?

As a charismatic carnivore that is vulnerable to extinction, many studies have been conducted on predation by the cheetah Acinonyx jubatus. Cheetah are generally considered to capture medium‐sized prey; however, which species are actually preferred and why has yet to be addressed. We used data from 21 published and two unpublished studies from six countries […]

Giraffes (Giraffa camelopardalis peralta) of Niger

Thirty years ago giraffes were found all over the Sudano-Sahelian area, from Mauritania to Chad. Over the last 20 years, due to loss of habitat and poaching, giraffe populations have decreased. In Niger large herds were present in the Tanout area, between Agadez and Zinder, but they disappeared because of recurring drought. During the eighties, […]
