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 gorillas and chimpanzees. Other species of insects wore eaten… Expand

Diet and seasonal changes in sympatric gorillas and chimpanzees at Kahuzi–Biega National Park
TLDR
A comparison of dietary overlap between gorillas and chimpanzees across habitats suggests that sympatry may not influence dietary overlap in fruit consumed but may stimulate behavioral divergence to reduce feeding competition between them. Expand
Composition of the diet of chimpanzees and comparisons with that of sympatric lowland gorillas in the lopé reserve, gabon
TLDR
The major differences between chimpanzee and gorilla diet at Lopé were the larger quantities of vegetative foods regularly eaten by gorillas and their ability to resort to a diet dominated by vegetative Foods when fruit was scarce, and the diets of the two species showed greatest divergence. Expand
New insights in insect prey choice by chimpanzees and gorillas in southeast Cameroon: the role of nutritional value.
TLDR
The insect diet of chimpanzees and gorillas living at the northern periphery of the Dja Biosphere Reserve in southeast Cameroon and its nutritional contribution is described and the chemical composition and nutrient intake of fruit and foliage in their diets should be investigated. Expand
Intestinal parasites of sympatric gorillas and chimpanzees in the Lopé Reserve, Gabon.
TLDR
Entodiniomorph ciliates, which occurred frequently in both ape species in the Lopé survey and in all previous coprological surveys of wild apes, may be symbionts involved in cellulose digestion. Expand
Temporal Variation in Insect-eating by Chimpanzees and Gorillas in Southeast Cameroon: Extension of Niche Differentiation
  • I. Deblauwe
  • Biology
  • International Journal of Primatology
  • 2009
TLDR
Investigation of seasonality in fruit-, foliage-, insect-, and meat-eating by great apes in southeast Cameroon via indirect methods and measured activity and nest densities of insect prey found niche differentiation in their insect diet. Expand
Present Status and Conservation of Sympatric Populations of Gorillas and Chimpanzees
The distribution of gorillas and chimpanzees overlaps extensively in eastern Zaire. A similar density is estimated for the 2 kinds of ape in lowland tropical forests, while the density is higher for… Expand
Fallback foods and dietary partitioning among Pan and Gorilla.
TLDR
Although there was extensive overlap in the preferred fruits of these two species, gorillas tended to consume fewer fruits with prolonged availability while chimpanzees consumed fruits with large seasonal fluctuations, which shaped different social features between sympatric gorillas and chimpanzees.

An Analysis of Insectivory in Cross River Gorillas (Gorilla gorilla diehli) in the Tofala Hill Wildlife Sanctuary, Cameroon
TLDR
This study is the very first confirmation that Cross River gorilla (CRG) feed on insects; Dorylus ant and Macrotermes sp. Expand
Insectivory by Gorilla gorilla gorilla in Southeast Cameroon
TLDR
The study suggests the existence of temporal variation in ant- and termite-eating by gorillas, and compares the overall frequency of insectivory with those at other sites in Central Africa indicate a possible effect of forest disturbance on the insectivorous behavior of gorillas. Expand
Western lowland gorillas (Gorilla gorilla gorilla) as seasonal frugivores: Use of variable resources
  • M. Remis
  • Biology, Medicine
  • American journal of primatology
  • 1997
TLDR
The gorillas studied at Bai Hokou, Central African Republic, between August 1990 and October 1992 consumed 239 kinds of foods from 138 species of plants and invertebrates, including the fruits of 77 species, which shaped the foraging and ranging patterns of western lowland gorillas. Expand

Composition of the diet of lowland gorillas at Lopé in Gabon
TLDR
This report describes the composition of the diet of lowland gorillas, Gorilla gorilla gorilla, at Lopé in central Gabon, which is the most frugivorous population studied so far. Expand
The ant-gathering behaviour by the use of tools among wild chimpanzees of the Mahali Mountains
TLDR
Ant-gathering was seen during the time when chimpanzees usually take a rest between the two intensive feeding periods of a day, implying that ant-g gathering by use of tools is a kind of luxury. Expand
The natural history of the chimpanzee (Pan troglodytes verus) at Mt. Assirik, Senegal
TLDR
Chimpanzees appear to specialise in nocturnal prosimians as mammalian prey, and there is less forest and woodland at Mt. Assirik than at any other site where chimpanzees have been studied. Expand

The gorillas' behavioral responses to environmental complexity lend general support to recent ideas concerning the evolution of their social system. Expand
Tool use by wild chimpanzees in feeding upon driver ants
TLDR
It is concluded that ants may constitute a significant chimpanzee dietary component and that the dipping tools and techniques are relatively stereotyped in form. Expand
Brief report: Chimpanzees, tools, and termites: New record from Gabon
TLDR
Wild chimpanzees in northeastern Gabon use tools made of vegetation to obtain termites (Macrotermes? nobilis) for food, and there are signs that they also use stouter tools, perhaps to perforate the mounds of the termites. Expand
Insectivory by Gorillas
TLDR
Invertebrates occur in large numbers on the food plants of the gorillas of the Virunga Volcanoes of East Central Africa, and inadvertent insectivory is probably even more prevalent in lowland forests. Expand
