摘要: Spatial and temporal habitat use of kob antelopes (Kobus kob) have been investigated in the Comoe National Park (Ivory Coast, West Africa) by radio telemetry. A total 23 were equipped with collars tracked for up to 15 months. Home ranges males smaller those females larger than expected from theoretical models. Adult used areas adult did not show seasonal home range shifts. Daily distances travelled differ between sexes. Kob walked less during night day covered shorter wet season. Whereas an increase overlap resulted higher rates association among individuals, adults mixed sexes was correlated degree overlap. Territorial behaviour predator avoidance are suggested explain sex-specific differences size deviation predicted sizes. Predator is presumed as main reason reduced walking at well Reproductive feeding ecology assumed determine conspecifics. Resume On a etudie par radio-telemetrie l'utilisation spatiale et temporelle de l'habitat les cobes au Parc (en Cote d'Ivoire, Afrique l'Ouest). On equipe un colliers on suivis pendant 15 mois (pour certains). L'espace vital des mâles etait plus petit celui femelles grand que ce quoi s'attendait d'apres modeles theoriques. Les adultes couvraient une zone reduite ne deplacaient pas leur espace en fonction saisons. parcourues chaque jour etaient memes pour deux se moins la nuit le jour, courtes saison pluies. Alors qu'une augmentation du recouvrement entre espaces vitaux aboutissait taux superieur d'associations individus, l'association d'adultes n'etait liee vitaux. suggere comportement territorial l'evitement predateurs pourraient expliquer differences, specifiques sexe, dimension l'espace rapport aux dimensions prevues. suppose est raison principale limitation deplacements ainsi qu'en reproducteur l'ecologie alimentaire determinent degre d'association membres meme espece.
