Chimpanzee (Pan troglodytes) Space use in a Sanctuary Setting
Studies of chimpanzee space use can provide information about chimpanzees’ preferences and welfare. This study examined the space use of 12 chimpanzees at Fauna Foundation, a chimpanzee sanctuary located in Carignan, Québec, Canada. Observers recorded the chimpanzees’ location, elevation, …

Paternity and father-offspring relationships in wild chimpanzees, Pan troglodytes schweinfurthii.
… important in a patrilineal species such as chimpanzees as males will remain with fathers and other paternal kin for life, as will females until they disperse. Thus, this study aimed to further our understanding of importance of paternal kinship in social behavior by examining the most direct …

The Effect of Sound on Captive Chimpanzees (<i>Pan troglodytes</i>)
… primates are not as well understood. Captive chimpanzees are exposed to markedly different acoustic environments than their wild counterparts. This study assessed the organic soundscape of a chimpanzee sanctuary, the Fauna Foundation, in Carignan, Québec, Canada. Noninvasive, observational data …

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 …

A Cognitive Task as Enrichment for Chimpanzees (<i>Pan troglodytes</i>) in Sanctuary
<p>Chimpanzees (<em>Pan troglodytes</em>) hold an especially powerful attraction for researchers interested in cognition and how it developed to the degree observed in humans specifically and primates more generally. Chimpanzees are behaviorally complex primates with compelling data supporting …

Differences in the Communicative Behavior and Neurobiology of Chimpanzees (Pan troglodytes) and Bonobos (Pan paniscus)
<p>Chimpanzees and bonobos have distinctly different vocalizations, but it is unclear why these differences have evolved. We hypothesized that differences in habitat and feeding ecology have selected for bonobos to have an increased reliance on vocal communication compared to chimpanzees. To …

Effect of Group Size on the Activity Budget of Two Captive Chimpanzees (<i>Pan troglodytes</i>)
<p>Captive facilities housing chimpanzees are required to provide adequate care and provisions such as dietary, social, and environmental enrichment to promote the psychological well-being of the apes in their care. Chimpanzees are social creatures and changes in groups as well as relocation to a …

Comparison of Chimpanzee (Pan Troglodytes) Behavior on Tour and Non-Tour Days at Chimpanzee Sanctuary Northwest
… effect of a visitor program on captive chimpanzees’ (<em>Pan troglodytes</em>) behaviors at Chimpanzee Sanctuary Northwest (CSNW) in Cle Elum, Washington. I used focal animal sampling to score behaviors from an ethogram of affiliative, aggressive and abnormal chimpanzee behaviors, as well as …

A comparison of the seed dispersal service offered by chimpanzees (Pan troglodytes) and gorillas (Gorilla gorilla)
The handful 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 …

Effects of Different Housing Configurations on Captive Chimpanzee (<i>Pan troglodytes</i>) Behavior in Holding Area During Construction
… effects different housing configurations on chimpanzees in a zoological environment during a period of construction. I collected noninvasive, observational data at the Oregon Zoo in Portland, Oregon on a small group of chimpanzees, three females and one male, between the ages of 45 and 50 that …

A Comparison of Chimpanzee (Pan Troglodytes) Responses to Caregiver Use of Positive Reinforcement Training (PRT) and Species-Specific Behaviors (SSB)
… (PRT) and unstructured interactions (UI) on chimpanzee (<em>Pan troglodytes</em>) behavior. In the PRT condition, a caregiver interacted with a chimpanzee to condition behaviors for 10 min. In the UI condition, a caregiver interacted without PRT for 10 min. Participants were five chimpanzees in a …

Love, hatred and indifference in chimpanzees: Personality, Subjective Well-Being, and dyadic-level behavior in captive chimpanzees (Pan troglodytes): Does something more than rank, age and sex drive the nature of interpersonal relationships in chimpanzees?
… studies: the first focuses on reliability of chimpanzee personality and subjective well-being (SWB) scores, the second on validating those scores by comparing them to subjective assessments of behavior in dyads. The first measured reliability of scores of personality and subjective well-being …

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 …

Comparisons of the socio-behavioral differences between chimpanzees (Pan troglodytes) and bonobos (Pan paniscus), investigating the impact of a naturally occurring polymorphic microsatellite deletion in the 5’ flanking region of arginine vasopressin receptor 1a (AVPR1a) on gene expression and sociality within the Pan genus
<p>Among the great apes, chimpanzees are unique in having a polymorphic deletion of a ~350bp microsatellite containing region (DupB) in the 5’ flanking region of the arginine vasopressin receptor 1a (AVPR1a) gene. This results in three genotypes (DupB+/+, DupB+/- and DupB-/-) of AVPR1a in …

Genomic signatures of recent selection at HIV host susceptibility genes in a Central African human population
… immunodeficiency virus (SIV) strains from chimpanzees to human populations produced the current HIV-1 pandemic. We hypothesized that Central African human populations may have been exposed to SIV prior to the current pandemic, and that previous local outbreaks may have selected for genetic …

Chimpanzee conservation in light of impending iron ore mining project in SE Senegal
… conservation problems faced by savanna chimpanzees (<i>Pan troglodytes verus</i>). As mining and, subsequently, human populations increase in Senegal, chimpanzee populations will likely be displaced from areas of suitable habitat. To understand the effects of human disturbances on chimpanzee …
