La dissémination des graines par les cercopithécides forestiers africains

Abstract : An attempt is made to estimate the relative frequency of synzoochory and endozoochory of seeds by five species of African forest cercopithecines, using 250 stomach contents from wild monkeys hunted by native poachers around Makokou, NE Gabon. It is shown, (1) that the mean frequency of endozoochory by the species concerned is relatively low, 37.2% ; (2) that the mean frequency of destruction of ingested seeds increases with their size ; (3) that ingested seeds of a given plant species can be dispersed either by endozoochory or synzoochory by a same primate consumer ; and (4) that phylogenetically-related monkeys can disperse in different ways the seeds of a given plant species. Consequently, the advisability of classifying plants into synzoochorous or endozoochorous species is questioned.
