Diet choice of large carnivores in northern Cameroon

The diet of African wild dogs, lions and spotted hyenas was studied in the woodland savannah of Faro National Park and surrounding hunting zones in northern Cameroon during the dry season. Faecal analysis revealed that the diet of the three large carnivores overlaps considerably. Frequencies of prey remains of large and medium-sized antelopes were highest, with Buffon’s kob being by far the most common prey species. Carnivores seem to consume most abundant prey species. No prey item of domestic livestock

Phenotypic matching by spot pattern potentially mediates female giraffe social associations

Animal color pattern is a phenotypic trait that may mediate assortative mixing (also known as homophily), whereby similar looking individuals have stronger social associations. Masai giraffe (Giraffa camelopardalis tippelskirchi) coat spot patterns show high variation and some spot traits appear to be heritable. Giraffes also have high visual acuity, which may facilitate intraspecific communication and recognition based on spot patterns. Giraffe groupings are dynamic, merging and splitting throughout the day, but females form long-term associations. We predicted that adult female

Changes of population trends and mortality patterns in response to the reintroduction of large predators: The case study of African ungulates

Large predators have been reintroduced to an increasing number of protected areas in South Africa. However, the conditions allowing both prey and predator populations to be sustained in enclosed areas are still unclear as there is a lack of understanding of the consequences of such reintroductions for ungulate population dynamics. Variation in lion numbers, two decades after their first release, offered a special opportunity to test the effects of predation pressure on the population dynamics of seven ungulate species in

Evaluation de la capacité de charge pour les girafes dans la réserve de biosphère de Gadabédji, Niger

Dans le cadre de la conservation de la girafe (Giraffa cameleopardalis perralta L.), huit individus provenant de Kouré ont été réintroduites dans la réserve de biosphère de Gadabédji. Trois ans après cette introduction, il s’avère important d’approfondir les connaissances sur l’écologie de l’espèce. C’est dans ce sens que la présente étude a été initiée dans le but de déterminer la capacité de charge de la réserve de biosphère de Gadabéji (RBG). En effet, les biomasses foliaires totales et accessibles de

Connaissances locales sur la conservation de la girafe de l’Afrique de l’Ouest (Giraffa camelopardalis peralta) dans la zone Girafe et la Réserve de Biosphère de Gadabedji au Niger

Le dernier troupeau de girafe de l’Afrique de l’Ouest (Giraffa camelopardalis peralta) vit au Niger dans un milieu fortement anthropisée. Cette contrainte l’oblige à partager les ressources naturelles avec les humains d’où la naissance d’un conflit homme-faune. La présente étude sur la dimension humaine dans la conservation de la girafe a été menée dans deux zones de distribution des girafes au Niger dénommée zone girafe et Réserve de Biosphère de Gadabedji (RBG). Elle a pour objectif de contribuer à une

Estimating Giraffe (Giraffa Camelopardalis) Population Size And Survival Rates In South Luangwa Valley, Zambia

Giraffe populations across their range have declined significantly over the past 40 years. Recent studies of these declines noted that conservation efforts often lack basic population estimates and descriptions of demographic parameters such as sex- and age-specific survival rates. I addressed those research needs for a geographically-isolated population of giraffes (Giraffa camelopardalis) in South Luangwa Valley, Zambia. During 2016 to 2018, collaborators opportunistically photographed giraffes throughout South Luangwa National Park and adjacent Lupande and Lumimba Game Management Areas. Given that

Skin Papillomas in an Impala (Aepyceros melampus) and a Giraffe (Giraffa camelopardalis)

Viral particles, typical of the papovavirus family, were demonstrated by electronmicroscopy in small papillomas found on the feet of an impala (Aepyceros melampus) and on the face of a giraffe (Giraffa camelopardalis) in Kenya. Histologically the tissues proved to be typical papillomas. The viral particles measured 38 nm and 40 nm in diameter in all tissue sections from the impala and giraffe respectively.

Usage of specialized fence-gaps in a black rhinoceros conservancy in Kenya

Fencing is increasingly used in wildlife conservation. Keeping wildlife segregated from local communities, while permitting wildlife access to the greater landscape matrix is a complex task. We investigated the effectiveness of specially designed fence-gaps on animal movement at a Kenyan rhinoceros conservancy, using camera-traps over a four-year period. The fence-gap design restricted the movement of black (Diceris bicornis) and white rhinoceroses (Ceratotherium simum simum) but permitted the movement of other species. We documented over 6000 crossing events of over 50

Physical meat quality characteristics of Angolan giraffe (Giraffa giraffa angolensis) as affected by sex and muscle

Giraffe numbers grow exponentially when farmed, necessitating periodic culling. This study quantified the effect of sex and muscle on the physical quality characteristics of eight giraffe muscles. The Warner-Bratzler shear force (WBSF) was the only parameter to be affected by an interaction between sex and muscle (P < 0.001), although the interaction for the CIE L* values tended towards significance (P = 0.054). Cooking loss (male = 41.6 ± 0.35%; female = 40.7 ± 0.33%; P = 0.024) and CIE

Habitat use analysis of the Angolan giraffe (Giraffa giraffa angolensis) in the Kalahari ecosystem

Giraffe populations across the African continent have declined over the past decades, mainly due to habitat loss and fragmentation of subpopulations. To fight the decrease in numbers of the different giraffe species, conservation actions have been and are currently in place, such as translocations into protected areas and reintroductions into areas where giraffes have disappeared. In Namibia, the Angolan subspecies is widely spread and mostly found on private land, which offers the opportunity to study the species in closed environments,
