Distribution, census and habitat preferences of primate species in the Dahomey Gap (West Africa), with particular emphasis on the Red-bellied Guenon (Cercopithecus erythrogaster erythrogaster)

Abstract

The Dahomey Gap, a forest-savanna mosaic found in Togo and Benin, creates a discontinuity in the lowland forest zone of West Africa. Few primate studies have been conducted in this area. This study was intended to 1) survey diurnal primate species present in the Dahomey Gap; 2) evaluate two methods for censusing red-bellied guenons (Cercopithecus erythrogaster erythrogaster); and 3) compare primate community structure in different forest types in southern Benin. During this study: 1) seven diurnal primate species were found in Togo and seven in Benin; 2) a higher population estimate for the redbellied guenon was derived with the point count method than for the line transect method, and 3) differing structures in primate communities were correlated with the different habitat types. The results from this study can be used in the elaboration of management plans for this region.
