Captive Chimpanzees' (<i>Pan troglodytes</i>) Night-Time Enrichment Selection and Use
<p>Captive chimpanzees (<em>Pan troglodytes</em>) engage with enrichment objects extensively during the daytime, yet relatively little is known regarding their use of available enrichment at night. This study examined night-time enrichment use in three adult chimpanzees at the Chimpanzee and Human …

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 …

Reaction to Stimulus Figures in Chimpanzee Drawings
Seven captive chimpanzees (<em>Pan troglodytes</em>) produced drawings at the University of Oklahoma between November 1971 and November 1972. Chimpanzees drew on sheets of paper that were either blank or had a stimulus. The stimulus was located in the center or offset from the center. These …

Re-Evaluating Captive Chimpanzee “Dominance”: Dominance Hierarchy and Chimpanzee-Caregiver Relationships at Chimpanzee Sanctuary Northwest
… the prominent connection of caregivers to captive chimpanzee social networks. Chapter I addresses current and past variability in behavioral measures and statistical methods to derive dominance rankings. I propose a novel approach to using existing statistical techniques to analyze …

Chimpanzee Early Life Experiences and Responses to Caregiver Use of Species-Specific Behavior
<p>More than 1,400 chimpanzees live in captivity in the US and each has complex social needs. The humans who care for captive chimpanzees occupy a place within chimpanzee social structures and their actions have consequences on chimpanzee behavior and welfare. Two studies compared chimpanzee …

A Comparison of Chimpanzee (Pan Troglodytes) Responses to Caregiver Use of Positive Reinforcement Training (PRT) and Species-Specific Behaviors (SSB)
… without PRT for 10 min. Participants were five chimpanzees in a sanctuary setting. Chimpanzees were also videotaped for 10 min after trials (PTP) and for 10 min in a matched control (MC) period on a different day. From these videotapes experimenters coded chimpanzee behaviors and calculated …
