Chimpanzees (Pan troglodytes verus) and their mammalian sympatriates: Mt. Assirik, Niokolo-Koba National Park, Senegal
Western gorilla diet: A synthesis from six sites
The objective of this paper is to collate information on western gorilla diet from six study sites throughout much of their current range, including preliminary information from two sites (Afi and Lossi), where studies of diet have begun only recently. Food lists were available from each site, derived from indirect signs of gorilla feeding (such as feces), with some observational data. Important staple, seasonal, and fallback foods have been iden…

Charting Cultural Variation in Chimpanzees
Cultural variation among chimpanzee communities or unit-groups at nine long-term study sites was charted through a systematic, collaborative procedure in which the directors of the sites first agreed a candidate list of 65 behaviour patterns (here fully defined), then classified each pattern in relation to its local frequency of occurrence. Thirty-nine of the candidate behaviour patterns were discriminated as cultural variants, sufficiently frequ…

Lowland gorillas and seed dispersal: The importance of nest sites
Lowland gorillas eat the fruit and disperse the seeds of many tree species in the Lopé Reserve, Gabon. This study aimed to show whether deposition of seeds at gorilla ground nest sites conferred any advantage for germination and seedling establishment as compared to the fate of seeds deposited in gorilla dung on trails or under parents. Four tree species were chosen for study, which had a range of fruit types and fruiting patterns but which were …
The primate community of the Lopé reserve, Gabon: Diets, responses to fruit scarcity, and effects on biomass
The diets of all diurnal primates (Gorilla g. gorilla, Pan t. troglodytes, Mandrillus sphinx, Colobus satanas, Cercocebus albigena, Cercopithecus nictitans, C. pogonias, C. cephus) in the Lópe Reserve, central Gabon, are described from qualitative and quantitative data collected over 10 years. A total of 397 foods were recorded, of which 91% were from plants. The diet of seven of the eight species were numerically dominated by fruit, the exceptio…
Why Don't Chimpanzees in Gabon Crack Nuts
Ranging and social structure of lowland gorillas in the Lopé Reserve, Gabon
INTRODUCTION At the time of the first Wenner-Gren conference on ‘The Great Apes’ in 1974, western lowland gorillas had been little studied in the wild. Apart from the pioneering field study of Jones & Sabater Pi (1971), knowledge of gorilla ecology in central west Africa came from the anecdotes of explorers and big game hunters. Jones & Sabater Pi, working in Equatorial Guinea (Rio Muni), found that gorillas lived in smaller groups and ate more f…
Ten days in the life of a mandrill horde in the Lopé Reserve, Gabon
Mandrills have long been known to form large aggregations in the wild, but it has proved difficult to obtain detailed information on the socioecology of these groups. An unusually large (>600) horde of mandrills was followed for ten days during the 1995 dry season in Central Gabon, and data were collected on group composition and ecology while the mandrills were in an area of forest-savanna mosaic habitat in the north of the Lopé Reserve. Three s…

Composition of the diet of chimpanzees and comparisons with that of sympatric lowland gorillas in the lopé reserve, gabon
Over an eight‐year period, a total of 174 food items were recorded for chimpanzees ( Pan t. troglodytes ) in the Lopé Reserve in central Gabon. Plant foods, principally fruit, dominated the diet but insects were eaten regularly, and predation on at least three species of mammal occurred infrequently. The diversity of the vegetative component of the diet (leaves, stems, and bark) was probably underestimated by fecal analysis. Comparison of chimpan…
Insect‐eating by sympatric Lowland gorillas ( Gorilla g. gorilla ) and chimpanzees ( Pan t. troglodytes ) in the Lopé Reserve, Gabon
Sympatric populations of lowland gorillas ( Gorilla gorilla gorilla ) and chimpanzees ( Pan troglodytes troglodytes ) in the Lopé Reserve in central Gabon consumed insects at similar average frequencies over a 7‐year period (30% versus 31% feces contained insect remains). Data came mostly from fecal analysis supplemented by observation and trail evidence. The weaver ant ( Oecophylla longinoda ) was the species eaten most frequently by both gorill…
Foraging profiles of sympatric lowland gorillas and chimpanzees in the Lopé Reserve, Gabon
Comparison of the diets of sympatric gorillas and chimpanzees allows an analysis of niche separation between these two closely related species. Qualitatively, their diets are similar, being dominated by an equally diverse array of fruit species complemented with vegetative plant parts, seeds and insects. Gorillas eat more vegetative plant parts than do chimpanzees, but niche separation is most obvious in periods of fruit scarcity when the two spe…
Gorilla diet in the Lopé Reserve, Gabon: A nutritional analysis
Composition of the diet of lowland gorillas at Lopé in Gabon
This report describes the composition of the diet of lowland gorillas, Gorilla gorilla gorilla , at Lopé in central Gabon. This population inhabits mature evergreen tropical forest and is not habituated to human observers. Data were collected during 6 years of an ongoing long‐term study, from feeding‐trails and by direct observation, but mostly by fecal analysis. Gorillas ate 182 plant foods from 134 species and 36 families. The fruit diet was di…
Diet of wild chimpanzees ( Pan troglodytes verus ) at Mt. Assirik, Senegal: I. Composition
The composition of the diet of a savanna‐living population of wild chimpanzees ( Pan troglodytes verus ) at Mt. Assirik in Senegal is presented. The study site had a prolonged dry season, high temperatures, and vegetation dominated by grasses. Data came from direct observation, fecal specimens, and feeding traces; thus, strict criteria for acceptance of the indirect data were specified. Composition of diet was given in terms of species and family…

Nationwide census of gorilla ( gorilla g. gorilla ) and chimpanzee ( Pan t. troglodytes ) populations in Gabon
A census was made of gorilla and chimpanzee populations throughout Gabon between December 1980 and February 1983. The aim of the census was to estimate the total numbers of both species and describe their distributions. The method was based on nest counts from line transects which allowed the calculation of population densities of all individuals except suckling infants. Fifteen types of habitat were recognized and defined in terms of their struc…
Social organization of savanna-dwelling chimpanzees,Pan troglodytes verus, at Mt. Assirik, Senegal
Evidence for a Social Custom in Wild Chimpanzees
Can the concept of culture be applied validly to any of the natural behaviours exhibited by non-human primates? We compare aspects of social grooming shown by two separate populations of wild chimpanzees (Pan troglodytes) in western Tanzania. We present as an example a behaviour pattern, the grooming-hand-clasp, which occurs commonly in the chimpanzees of Kasoge but is absent in the chimpanzees of Gombe. After discussing the problems of operation…

Sexual behaviour of group‐living adolescent chimpanzees
This paper reports a study of the heterosexual behavior of three male and four female captive adolescent chimpanzees living a semi‐natural life style in a large field enclosure. Observations made with binoculars from an over‐head deck were balanced over the daylight hours and the seven weekdays. We recorded 213 copulations in 741.25 hours of observation between February 14 and July 21, 1972. Analysis of the observations suggests that group‐living…
