Noninvasive genetic analysis for assessing the abundance of duiker species among habitats in the tropical forest of Moukalaba, Gabon

摘要: We investigated the relative abundance of four duiker species and environmental effect including human impacts on their in forest Moukalaba, Gabon. counted collected fresh faeces from duikers thirteen 2-km line transects established different types vegetation. Genetic identification showed that blue (Philantomba monticola), Ogilby’s (Cephalophus ogilbyi, which might include sister Peter’s Cephalophus callipygus), bay dorsalis), yellow-backed silvicultor) coexisted. analyses successfully identified duiker, are difficult to discriminate using other methods. The blue, Ogilby’s, were found all transects. dung was quite low compared species. This result suggests importance accumulating information regarding each for updating conservation status. count method with genetic may be useful this purpose. affected by impacts, while not impacts. lower young secondary forests, regenerating after significant disturbance. In contrast, generalized liner mixed model vegetation type nearer villages, due past hunting activity. difference among should considered management.
