Brashares and Arcese (1999a, b) suggest dominant male oribi Ourebia
ourebi restrict defecation volume and occurrence in order to increase the frequency of territory marking events.
The Biosphere Reserve also hosts a rich fauna (Poussy and Bakyono, 1991) consisting of mammal species such as the hippopotamus, elephant (Loxodonta africana Cuvier), bushbuck (Tragelaphus scriptus Pallas), roan antelope (Hippotragus equinus Desmarest), warthog (Phacocoerus africanus Gmelin), Oribi (Ourebia
ourebi Zimmerman), duiker (Sylvicapra grimmia L.), patas monkey (Erythrocebus patas Schreber), green monkey (Cercopithecus aethiops L.) and baboon (Papio Anubis Lesson) (ENGREF, 1989; Bouche, 2005; Dibloni, 2011).
We have found that in small antelope such as oribi (Ourebia
ourebi) (10 kg), nearly all mortality of adults is accounted for by predators; in zebra (Equus burchelli) (250 kg) this is about 73%, while in buffalo it is 23% (Sinclair 1977).

ourebi), and the very small dikdik (Rynchotragus (Mado qua) kirki).
It includes all the antelopes mentioned above, as well as the bushbuck (Tragelaphus scriptus), the red-fronted gazelle (Gazella rufifrons), the oribi (Ourebia
ourebi), and several duikers (Sylvi-capra grimmia, Cephalophus rufilatus), as well as the African elephant (Loxodonta africana), Cape buffalo (Syncerus caffer), giraffe (Giraffa camelopardalis), warthog (Phacochoerus aethiopicus), and anubis baboon (Papio anubis) and other monkeys.
in our study, this would be oribi Ourebia ourebi, warthog Phacochoerus aetiopicus and reedbuck Redunca redunca).

ourebi), the tiny dik-diks (Madoqua), and the even smaller royal antelope (Neotragus pygmaeus), the smallest living antelope, weighing only 7-9 lb (3-4 kg).
The other mammals include the Cape buffalo (Syncerus caffer), topi (Damaliscus lunatus), Coke's hartebeest (Alcela-phus buselaphus cokei), Grant's gazelle (Gazella granti), oribi (Ourebia
ourebi), warthog (Hylo-choerus), giraffe (Giraffa camelopardalis), African elephant (Loxodonta africana), hippopotamus (Hip-popotamus amphibius), black rhinoceros (Diceros bicornis), and seven species of primates.
