Re-Evaluating Captive Chimpanzee “Dominance”: Dominance Hierarchy and Chimpanzee-Caregiver Relationships at Chimpanzee Sanctuary Northwest
… 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 dominance ranks, …

Comparison of Chimpanzee (Pan Troglodytes) Behavior on Tour and Non-Tour Days at Chimpanzee Sanctuary Northwest
… potential 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 …

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 …

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, …

Retrotransposon mediated genomic fluidity in the human and chimpanzee lineages
… understood. The recently released human and chimpanzee draft genome sequences provide the opportunity to compare the human genome with the chimpanzee genome. Thus, we were able to assess how these elements expanded in primate genomes and how they create genomic instability during their …

The evolution of shelter: ecology and ethology of chimpanzee nest building
… depends on this basic trait. All great apes (chimpanzee, bonobo, gorilla, and orangutan) build analogous structures (called nests or beds) at least once a day throughout their adult lives, which suggests that this elementary technology was present before the hominid lines separated. This …

Chimpanzee conservation in light of impending iron ore mining project in SE Senegal
… existing 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 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 …

Chimpanzee ecology and interactions with people in an unprotected human-dominated landscape at Bulindi, Western Uganda
… outside of protected areas, the survival of many chimpanzee (Pan troglodytes) populations is dependant on their ability to adapt to human-dominated landscapes, and the willingness of local people to share their environment and resources with these large mammals. Unless hunted, chimpanzees may …

A 3D Geometric Morphometric Investigation of Relatedness in the Modern Human, Chimpanzee, and Homo naledi Postcranial Skeleton
… support Hypothesis 1 in both modern humans and chimpanzees, though the signal of relatedness is differentially expressed within and across elements. In modern humans, the calcaneus can be used to distinguish known close relatives from distantly related and unrelated individuals. The navicular …

Patterns and processes in chimpanzee hunting behaviour: the chimps and the carnivores: are they really so different?.
Chimpanzees and large, social, mammalian carnivores hunt similarly, yet few studies use comparative methodologies to help understand these animals hunting behaviour. This thesis investigates the extent of current knowledge of chimpanzee hunting in the context of what, how and why chimpanzees hunt. …

Determining fecal bacterial profiles of a human-habituated wild chimpanzee population in Mahale Mountains National Park, Tanzania
Intestinal flora of wild chimpanzee has not been studied. Fecal flora analyses currently give insight to this environment. We collected feces from twelve human-habituated wild chimpanzees in each of three age groups: four juveniles, four sub-adults, and four adults. We analyzed fecal samples using …

Effects of Different Housing Configurations on Captive Chimpanzee (<i>Pan troglodytes</i>) Behavior in Holding Area During Construction
… and 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 …

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 …

Landscapes of the apes: modelling landscape use of chimpanzees and early hominins across an environmental gradient.
… tools in investigating primate landscape use. Chimpanzees (Pan troglodytes) face habitat loss throughout their range, but their susceptibility to change remains unclear. Changing landscapes also played a vital role in human evolution, but evidence on early hominin behaviour remains limited. …

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 …

GREAT APE CONSERVATION IN THE MATRIX: INVESTIGATING THE SOCIO-ECOLOGICAL RESPONSES OF CHIMPANZEES LIVING IN A FOREST-FARM MOSAIC, UGANDA
… This study investigates the responses of Eastern chimpanzees (Pan troglodytes schweinfurthii) in a newly studied site in Uganda with a history of negative human-chimpanzee interactions. I take a comparative approach, evaluating the differences in feeding strategies and activity budgets between …

The ancient and recurrent evolution of Apobec3 antiviral activity in primates
… human populations. First, I show that human and chimpanzee orthologues of Apobec3DE inhibit retrotransposons that are currently active in hominids. Chimpanzee Apobec3DE also potently restricts lentiviruses, unlike human Apobec3DE, which has weaker antiviral activity against retroviruses. I also …

Drumming Trees and Stone Percussion: An Evolution of Rhythm

The second half of the thesis examines rhythmicity in tool use and manufacture, culminating in an experimental archaeology study that assesses rhythm and Achulean hand-axe quality. *Chimpanzee Buttress …
