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. …

Scratching the Surface: A Content Analysis of Gorillas as Zoogeomorphic Agents
Gorillas are among the most charismatic and well-researched species on the planet, yet their role as zoogeomorphic agents has gone largely overlooked. Zoogeomorphology is the study of animals as geomorphic agents, that is, their role in sculpting, modifying, and maintaining the earth’s physical …

Tourists, gorillas and guns: integrating conservation and development in the Central African Republic
Integrated conservation and development programs (ICDPs) are aimed at addressing both conservation and development issues through the involvement of local communities in the process of wildlife management. Typically this involves providing park-adjacent communities with conservation-related …

A comparison of the seed dispersal service offered by chimpanzees (Pan troglodytes) and gorillas (Gorilla gorilla)
… the dispersal service offered by chimpanzees and gorillas. Determining 'quality' requires a measure of the dispersal distance and the microsite to which the seeds are dispersed. In this study, I report the first estimate of seed dispersal curves for chimpanzees and gorillas. Seed dispersal curves …

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
… and used to monitor adrenal activity in gorillas. Measured cortisol increases in response to a known stressor (medical illness) provided a physical validation of the cortisol EIA and established biological relevance of the assay system. No significant differences in social behaviors …

The Spatial and Temporal Ecology of Seed Dispersal by Gorillas in Lopé National Park, Gabon: Linking Patterns of Disperser Behavior and Recruitment in an Afrotropical Forest
<p>Western lowland gorillas: <italic>Gorilla g. gorilla</italic>) consume large quantities of fruit and disperse a great number of seeds. The majority these seeds are dispersed intact and viable in the dung. Dung is often deposited around the rim of a night nest or at a nest-site. Gorillas often …

Salivary Biomarkers of Acute Stress and Insulin Sensitivity in Nonhuman Primates
… was collected twice daily for two weeks in gorillas (Gorilla g. gorilla), mangabeys (Cercocebus chrysogaster), red ruffed lemurs (Varecia rubra) and mongoose lemurs (Eulemur mongoz). Hormones were analyzed with enzyme kinetic or immunoassays. Our study validated tools for analyzing …

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 …

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, …

Western Gorilla Social Structure and Inter-Group Dynamics
… the large scale society of western lowland gorillas, using novel technologies and analytical methods to overcome the considerable difficulties in studying large numbers of gorillas simultaneously. I use biases in movement patterns to investigate the cognitive rules used, and decisions made …

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 …

The Evolutionary Origins of Autism Associated Genes and Their Role in Great Ape Socio-Communicative Behavior
… in great apes such as bonobos, chimpanzees, and gorillas. Great apes are the closest relatives to humans on the phylogenetic tree. They are also one of the few animal groups that have complex social communication that share fundamental characteristics with human language. Therefore, increasing …
