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

Palewinged Starling gleaning on desert-dwelling Giraffe, northwestern Namibia

The Yellowbilled Oxpecker Bupgagus africanus, Redbilled Oxpecker B. erythrorhynchus, Cattle Egret Ardeola ibis and Fork-tailed Drongo Dicrurus adsimilis have all been observed in direct feeding association with Giraffe Giraffa camelopardalis. While the first two are highly adapted obligate ectoparasite gleaners, the latter two species are facultative ectooarasite gleaners that otherwise actively prey upon insects incidentally flushed by mammals. The allopatric Palewinged Starling Onychognathus nabourup has been observed to have an affinity with Klipspringer Oreotragus oreotragus, similar to that of the

The feeding ecology of a selective browser, the giraffe (Giraffa camelopardalis tippelskirchi)

A herbivore can manipulate certain factors of its feeding behavior in order to achieve the metabolic requirements for reproduction. These factors include choice of habitat in which to feed, the selection criteria for choosing food items, and the time allocated to feeding or devoted to other energy-consuming activities. The manipulation of these behavioural factors by giraffe in the Serengeti National Park, Tanzania is analysed in relation to the seasonal changes in the quantity and quality of the food resource. The

Conservation monitoring: estimating mammal densities in woodland habitats

Conservation and ecological monitoring programmes often estimate animal densities over time, but in wooded and forested areas practical techniques are still poorly developed. Here I have examined five simple methods of deriving densities of large and medium-sized mammals using line transects driven through miombo woodland habitat in Africa. These methods calculated area by dividing the number of individuals seen by (i) an average of each species’ sighting distances, (ii) a fixed 200 m belt width, (iii) the area visible from

The giraffe and its food resource in the Serengeti

The dynamics of the giraffe population of the Serengeti were quantified to ascertain the response of the population to the increasing biomass of the available browse resource. Aerial counts conducted in 1971 and 1976 together with analyses of fecundity and mortality data suggest a rate of population increase of some 5–6% per annum. Compared with the dynamics of a stable giraffe population in Nairobi National Park, the sub-adult components of the Serengeti regional populations are larger and juvenile growth rates
