Population status and feeding habits of the translocated sub-population of hunter's antelope or hirola (Beatragus hunteri, Sclater, 1889) in Tsavo East National Park, Kenya

摘要: Summary The population status and feeding habits of Hunter's antelope or hirola (Beatragus hunteri) in Tsavo East National Park were determined this study 1995. This is the first that has ever been undertaken on about 20 animals translocated to from South Garissa District 1963. Relevant data information collected using different ecological research techniques. A total eight nursery herds (5–11 individuals per herd) comprising 60 individuals, five lone bulls 11 sub-adults was observed. gave a estimate 76 entire area. Adult dominated (60.53%), indicating skew towards adults. The adult sex ratio biased females (43.42%). Hirola observed feed mainly short, green grasses. dominant species Panicum infestum, Digitaria rivae, Latipes senegalensis Cenchrus ciliaris. Occasionally, forbs (e.g. Portulaca oleraceae, Tephrosia subtriglora Commelina erecta). Results show growth sub-population low (1.8 year). Factors thought contribute include predation genetic variability. Resume Cette etude realisee en 1995 permis de determiner le statut et les habitudes alimentaires la d’antilopes Hunter, ou dans Parc Est. C’est premiere qui ait jamais ete entreprise sur cette d’hirola d’environ vingt animaux introduits au Est, provenance du sud, Les donnees informations interessantes ont recoltees moyen differentes techniques recherches ecologiques. On observe un huit hardes reproductrices individus par harde) comptant individus, cinq ma?les adultes solitaires onze subadultes solitaires. Ceci donne une estimation totale pour toute zone etudiee. constituent plus grande partie (60,53%), indiquant biaisee faveur des adultes. Le sex-ratio etait biaise femelles (43,42%). On que se nourrissaient principalement d’herbes courtes vertes. especes dominantes regime etaient A l’occasion, vu nourrir plantes succulentes (par ex. erecta). Les resultats montrent croissance sous-population parc faible (1,8 an). pense variabilite genetique pourraient e?tre facteurs contribuea croissance.
