The gut microbiome of the western lowland gorilla (Gorilla gorilla gorilla): implications for overall ecology
… of gut bacterial communities in western lowland gorillas (Gorilla gorilla gorilla). This primate species exhibits a set of unique ecological features that make it ideal to test hypotheses of how primates respond to change and the extent to which gut bacteria have impacted primate fitness, …

Visitor Effects on Western Lowland Gorillas (Gorilla gorilla gorilla)
… that come from housing bachelor groups of gorillas in zoos it is vital to be able to address any behavioral concerns brought about by complications of visitor effects. Five male western lowland gorillas (Gorilla gorilla gorilla) were observed at the St. Louis Zoo between June and July 2014. …

Gorilla-Visitor Interface at a Zoo Exhibit: Positioning Effects of Western Lowland Gorillas (Gorilla gorilla gorilla) and Zoo Visitors
… the relationship between visitors and gorillas in a zoo environment. The effect of gorilla proximity to visitor viewing areas on visitor attentiveness was examined in indoor and outdoor gorilla exhibits. Visitor experience surveys were collected from visitors exiting the outdoor …

Monitoring A Potentially Stressful Situation In Captive Western Lowland Gorillas (gorilla Gorilla Gorilla) Through Analysis Of Behavior and Urinary Cortisol
… the potential stress response of a captive gorilla group to short-term space restriction associated with temporary confinement to indoor housing facilities. The study duration was three months; one month of baseline data collection, one month of indoor restriction, and one month of …

A comparison of the seed dispersal service offered by chimpanzees (Pan troglodytes) and gorillas (Gorilla gorilla)
… of studies that have investigated chimpanzee and gorilla seed-dispersal identify these primates as important dispersal agents. These studies do not, however, make any measure of the 'quality' of the dispersal service offered by chimpanzees and gorillas. Determining 'quality' requires a measure of …

Gorilla Life-Stage Comparison of Head Orientation
… gaze can minimize potential conflict. Given that gorillas are highly sexually dimorphic, they may use this staring and gaze aversion strategy more than physical contact. Due to the shape of the eye and the pigmented sclera in some primates, eye gaze can be difficult to determine, whereas, head …

An Empirical and Theoretical Comparison of the Socio-ecological Behaviors of Captive Chimpanzees (Pan troglodytes), Bonobos (Pan paniscus), and Western Lowland Gorillas (Gorilla gorilla): Social Tolerance and Behavioral Responses to Changes in Food Quality and Distribution
<p>Chimpanzees and gorillas are sympatric in most of their range in Central Africa, however, bonobos do not overlap with either of the other two species. This difference has been hypothesized to be the main factor leading to the socio-ecological traits of each species. Access to, and competition …

Chromosomes and spermatozoa of the great apes and man
… the pygmy chimpanzee (Pan paniscus), the gorilla (Gorilla gorilla), and the orangutan (Pongo pygmaeus) have been analysed with chromosome banding techniques and compared to the human chromosome comple¬ ment. This has shown remarkable homologies between species, and presumed mechanisms of …

Variation and the evolutionary drivers of diversity in the genus Paranthropus
… drift). Extant species (Homo sapiens (N=150), Gorilla gorilla (N=150), Pan troglodytes (N=143) act as analogues for Paranthropus variance/covariance (V/CV). Results reveal a high magnitude of variation within and between species across mandibular and cranial regions, especially when including …

Pictorial Primates: A Search for Iconic Abilities in Great Apes
… of photographic recognition in picture-naïve gorillas, and recognition of line drawings in picture-experienced and language-competent bonobos. Only the latter study yielded evidence for recognition. The failures in the former study are discussed in terms of experimental shortcomings, and …
