The distribution of Cercopithecus (lhoesti) solatus, an endemic guenon of Gabon

Abstract

The species occurs in a 9500-10 300 km2 area. In the southwest, its distribution follows the limit of a specific forest type. The southern limit seems to coincide at least in part with increased elevation. Anthropic factors cannot account for such a restricted distribution, as C. solatus is also found in the degraded vegetation of the settled areas, where its abundance is apparently similar to that found in the primary lowland forest which covers most of its range. Historical factors which may explain the radiation of the lhoesti superspecies are discussed. -from Authors
