Spatio-temporal functional diversity of large herbivores in Mudumu National Park, northeastern Namibia

Functional diversity is a component of biodiversity that includes the range of roles that organisms perform in communities and can explain and predict the impact of organisms on ecosystems. Mudumu National Park is an important ecosystem that acts as a wildlife corridor for migratory fauna moving between Botswana, Namibia, Angola and Zambia. Thus, a thorough understanding of the functional diversity of large herbivores would assist with the management of the park. The present study examined large herbivore species contribution to

Using spot pattern recognition to examine population biology, evolutionary ecology, sociality, and movements of girafes: a 70‑year retrospective

Individual-based studies where animals are monitored through space and time enable explorations of ecology, demography, evolutionary biology, movements, and behavior. Here, we review 70 years of research on an endangered African herbivore, the giraffe, based on individual spot pattern recognition, and profile an example of a long-term photographic mark–recapture study of Masai giraffes in Tanzania. We illustrate how individual-based data can be used to examine the fitness consequence (variation in survival and reproduction) of extrinsic environmental factors or intrinsic traits

Prevalence of parasites of wildlife in Yankari game reserve and Sumu wildlife park in Bauchi State, Nigeria

The role of wildlife in the epidemiology of parasites in Yankari Game Reserve and Sumu Wildlife Park in Bauchi State, Nigeria was investigated by analysis of blood, faeces and ticks collected from 106 wildlife including 4 elephants (Loxodonta africana), 11 waterbucks (Kobus ellipsiprymus), 1 hartbeest (Alcelaphus baselaphus caama), 24 elands (Taurotragus oryx), 53 zebras (Equus quagga crawshayi), 1 kudu (Tragelaphus streptsiceros) and 12 wildebeest (Connochaetes taurinus). Blood samples were examined for haemoparasites by classical parasitological techniques i.e Geimsa’s stained thin,

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.
