Generation times in wild chimpanzees and gorillas suggest earlier divergence times in great ape and human evolution
Fossils and molecular data are two independent sources of information that should in principle provide consistent inferences of when evolutionary lineages diverged. Here we use an alternativeExpand

Wild chimpanzee infant urine and saliva sampled noninvasively usable for DNA analyses
In many genetic studies on the great apes, fecal or hair samples have been used as sources of DNA. However, feces and hairs are difficult to collect from chimpanzee infants under 3 years of age. AsExpand

Ranging behavior of Mahale chimpanzees: a 16 year study
We have analyzed the ranging patterns of the Mimikire group (M group) of chimpanzees in the Mahale Mountains National Park, Tanzania. During 16 years, the chimpanzees moved over a total area of 25.2Expand

Interspecies and intraspecies variations in the serotonin transporter gene intron 3 VNTR in nonhuman primates
A variable number of tandem repeat (VNTR) polymorphism based on a 16 or 17-bp unit has been reported in the third intron of the human serotonin transporter gene (5-HTT). VNTRs have been shown toExpand

Gene Flow and Genetic Diversity of Chimpanzees in Tanzanian Habitats
Abstract: Tanzania is located at the southeastern end of the eastern chimpanzee (Pan troglodytes schweinfurthii) distribution. Except for two national parks, their habitats have been degraded dueExpand

Improving the standards for gut microbiome analysis of fecal samples: insights from the field biology of Japanese macaques on Yakushima Island
Fecal DNA-based 16S ribosomal RNA (rRNA) gene sequencing using next-generation sequencers allows us to understand the dynamic gut microbiome adaptation of animals to their specific habitats.Expand

Mycophagy among Japanese macaques in Yakushima: fungal species diversity and behavioral patterns
Mycophagy (fungus-feeding) by Japanese macaques (Macaca fuscata yakui) in Yakushima has been observed by many researchers, but no detailed information is available on this behavior, including whichExpand

Sharing fruit of Treculia africana among western gorillas in the Moukalaba-Doudou National Park, Gabon: Preliminary report
We report the first 18 observed cases of fruit (Treculia africana) transfer among western lowland gorillas (Gorilla gorilla gorilla) in Moukalaba-Doudou National Park, Gabon. The fruit transferExpand

Population density and habitat preferences of forest duikers in Moukalaba-Doudou National Park, Gabon
We conducted a line-transect survey via direct observation to estimate the densities of forest duikers in Moukalaba-Doudou National Park, Gabon. Five 2-km line transects were established in differentExpand
