Ecological and Cognitive Influences on Orangutan Space Use
… evidence of habitual route networks in wild orangutans makes them ideal candidates for examining factors that affect the establishment and use of such networks. I completed three studies using new methodology to examine ecological and cognitive factors that may affect habitual route networks …

The Influence of Forest Structure on Sumatran Orangutan Nesting and Densities in the Lowland Dipterocarp Forests of North Sumatra
Prior studies on Bornean orangutans have suggested that orangutans were primarily selecting nest sites that provided more stable and sheltered platforms thereby offering greater comfort rather than selecting for nests which reduced the risk of predation by limiting access to ground predators …

A Novel SNP Genotyping Technique to Determine Orangutan Relatedness and Genetic Diversity at Camp Leakey in Tanjung Puting, Central Kalimantan
… of dispersal patterns in wild populations of orangutans (<em>Pongo </em>spp.) have sought to confirm behavioral observations that female orangutans tend to stay near their natal range while males disperse. In order to genotype a previously unsampled wild population of endangered orangutans at …

A mixed methods study of the habituation process in wild Bornean orangutans in West Kalimantan, Indonesia
… of habituation in a population of wild Bornean orangutans living in Gunung Palung National Park in West Kalimantan, Indonesia. To do so, I explore the impacts of habituation from three distinct but intersecting perspectives: behavioral, physiological, and relational. Following the …

Effects of a Riverine Dispersal Barrier on Cultural Similarity in Wild Bornean Orangutans (Pongo Pygmaeus Wurmbii)
… on a natural experiment to compare two wild orangutan populations. Sungai Lading, a previously unstudied, high-density population of wild Pongo pygmaeus wurmbii, was compared to Tuanan, a P.p.wurmbii population separated from Sungai Lading by an impassable river barrier, but ranging in a …

Palindromes on the human X chromosome : testis-biased transcription, gene conversion and evolution
… artificial chromosomes (BACs) from chimpanzee, orangutan and rhesus monkey genomic libraries containing sequence orthologous to several of the human X chromosome palindromes. We found some of the palindromes conserved in all species

Chromosomes and spermatozoa of the great apes and man
… 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 chromosome evolution have been …

Uncertainty Monitoring in Sprague-Dawley Rats (Rattus norvegicus)
… of rhesus monkeys, a capuchin monkey, an orangutan, a dolphin, pigeons, and rats. Previous research with rats has demonstrated inconsistent results (Foote & Crystal, 2007; Smith & Schull, 1989). In the current study, two Sprague-Dawley rats were tested in a tone-length discrimination task …

Did The Pandemic Lockdowns Affect The Welfare of The Sumatran Orangutans (Pongo abelii) At The Toronto Zoo?
… the welfare measures of the Toronto Zoo Sumatran orangutans (Pongo abelii) changed when visitors were reintroduced after the lockdowns were lifted. I compared behavioural and physiological measures of stress between the lockdown and visitor introduction phases. Specifically, I studied changes in …

DNA methylation analysis and identification of a novel antisense transcript in the Peg3 imprinted domain
… 2) called ZIM2as in the human, chimpanzee, and orangutan. In non-primate mammals, the 5’ side of the Peg3 imprinted domain is bounded by a cluster of olfactory receptor (OLFR) genes which may curtail the spread of imprinting. We report the presence of two previously unreported DMRs near the …

Comparative population genetics of the Hominoidea: An investigation of locus-specific and genome-wide influences
… (humans, chimpanzees, bonobos, gorillas, and orangutans) in order to test the hypothesis that a high variance in male reproductive success, as predicted from behavioral data, may influence levels of hominoid genetic diversity. First, comparative chromosome and mitochondria) DNA diversity was …

The evolution of shelter: ecology and ethology of chimpanzee nest building
… 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 thesis investigates the variability …

The Effect of Population History on Hominoid Intraspecific Cranial Shape Diversity: Combining Population Genetic and 3D Geometric Morphometric Data
… varied among hominoids. For example, Sumatran orangutan cranial shape diversity is more than twice that of all living humans. Here, the population history of each species, or sub-species, is considered as a force potentially structuring phenotypic variation. It is already well established that …

Museums and the construction of race ideologies: the case of natural history and ethnographic museums in South Africa
… the "Congolese Pygmy", who was displayed with an orangutan at the Bronx Zoo in America in 1906, and labelled "the Missing Link". Part of my attempt to understand the story of Benga, I set on a journey to track him to the United States (US). To point out and expose these human wrongs I incorporate …
