Yaws disease in a wild gorilla population and its impact on the reproductive status of males
We evaluated the prevalence of skin lesions in a gorilla population in the Republic of Congo. The observed lesions were typical of yaws, a treponematosis described in gorillas and humans living in tropical regions. Among the 377 gorillas identified, 17% presented skin lesions, mainly on their faces. The worst cases presented physical handicaps because of the deep lesions. As in humans, lesions break out when individuals are young. Lesions were mo…
Living in nonbreeding groups
The one‐male reproductive strategy implies that maturing males are temporarily excluded from reproduction. In gorillas, these excluded males live either solitarily or in nonbreeding groups (NBGs) that are devoid of adult females. The dynamics of NBGs are not well known. In this study, which was conducted on a gorilla population ( Gorilla gorilla gorilla ) of 377 individuals that visited the Lokoué clearing in the Republic of Congo, we detail how …
Significance of Riparian Forests for the Conservation of Central African Primates
Population and group structure of western lowland gorillas ( Gorilla gorilla gorilla ) at Lokoué, Republic of Congo
During a 17‐month study at the Lokoué clearing in Odzala National Park, Republic of Congo, we identified 377 western lowland gorillas. This population included 31 solitary males, 37 breeding groups, and eight nonbreeding groups. Its age‐ and sex‐class structure was similar to those observed at two other clearings in the same forest block. However, the size of breeding groups varied with site (either clearing or forest sites). At Lokoué, breeding …
Mineral content as a basis for food selection by western lowland gorillas in a forest clearing
The forests in northwest Republic of Congo contain a number of herbaceous swamp clearings that provide foraging sites for lowland gorillas ( G.g. gorilla ). A 10‐month study at the Maya Nord clearing (Parc National d'Odzala) showed that feeding activities occupied 72% of the time visiting gorillas spent on the clearing. They fed on four plant species: Enydra fluctuans (Asteraceae), Cyperus sp., Pycreus mundtii , and Rhynchospora corymbosa (Cypera…
Primate Diet and Biomass in Relation to Vegetation Composition and Fruiting Phenology in a Rain Forest in Gabon
Testing the reliability of noninvasive genetic sampling by comparing analyses of blood and fecal samples in Barbary macaques ( Macaca sylvanus )
Genetic studies of wild animal populations are often hindered by difficulties in obtaining blood samples. Recent advances in molecular biology have allowed the use of noninvasive samples as sources of DNA (e.g., hair or feces), but such samples may provide low‐quality DNA and prevent the determination of true genotypes in subsequent DNA analysis. We present a preliminary study aimed at assessing the reliability of using fecal samples for genotypi…
Population structure and group composition of western lowland gorillas in North-Western Republic of Congos
Population studies are an essential part of conservation actions. Under exceptional observation conditions we studied a western lowland gorilla population visiting the Maya salt-clearing (north of the Parc national d'Odzala, P.N.O., Congo) over an 8 month period; 36 groups and 18 solitary individuals (a total of 420 individuals) have been identified visiting the clearing, which suggests a high gorilla density in the region. Ninety-six percent of …
