Hormones and Body Size *Evolution in Old World Monkeys
This research shows that similar adult body size can be attained despite differences in levels of growth regulatory hormones during development. Results also demonstrate that absolute hormone levels during growth do not necessarily relate to adult size, contrary to the findings of previous research …

Enrichment Assessment for Geriatric African Old World Monkeys under Human Care
… enrichment regimes used for geriatric African Old World monkeys living under human care are effectively eliciting affiliative and active behaviors. I wanted to determine if alternating enrichment types used by the zoo staff were eliciting different social behaviors and locomotion in non-human …

The Evolution of the Viral RNA Sensor OAS1 in Old World Monkeys and Cetartiodactyls
… by a broader survey of the gene in nineteen Old World monkeys. My research found that at the species level, macaques exhibit extremely high diversity with intriguing similarities to that previously found in chimpanzees. Across Old World monkeys, I identified commonly shared patterns of …

The natural history of a lost sense
… that the organ is vestigial in humans and Old World monkeys. Possible explanations for the loss of the vomeronasal organ in these groups are described and evaluated. Notably, the development of tri-color vision may have replaced pheromones for sexual selection in these lineages. This may …

From Fossils to Function: Exploring the Evolutionary And Functional Diversity Of HERV Envelope Proteins Across Primate Lineages
… that resulted in an env variant specific to Old World Monkeys. The exhaustive analysis of HML2 in humans and Macaque genomes indicated the divergent nature of env gene due to recombinations, we further aimed to reconstruct representative Env prototype sequences and screen them across the …

The interaction between NS1B protein of influenza B virus and the ubiquitin-like modifier ISG15 : insights into a unique species specific property of the virus
… was found to bind ISG15 homologs from human and old world monkeys like Rhesus macaques and African green monkeys but not those from mouse or canines. These findings were extended by identifying the hinge between the N and C terminal domains of ISG15 as one of the major determinants of species …

Behavioral Mechanisms of Δ9-THC in Nonhuman Primates
… been established in one laboratory using New World primates (squirrel monkeys). In Chapter 2, THC and the synthetic cannabinoid agonist CP55,940 were made available for SA in Old World monkeys, a species more closely related to humans, by using similar parameters deemed successful in squirrel …

The Impact of Host Factors on Retroviral Evolution and the Identification of a Novel Receptor That Was Used by an Ancient Primate Retrovirus
… that are found in the genomes of a variety of old world primates, but are absent from the human genome. The nonexistence of human CERV1 and CERV2 homologues is peculiar given the numerous apparent cross-species transmissions that occurred between ancestors of old world monkeys, gorillas, and …

Analysis of seasonal variation in dietary composition and behaviour of wild chacma baboons (Papio ursinus) in two habitats of different human influence around windhoek, central Namibia
… “generalist diet” of these well documented old-world monkeys while also providing an alternative method to enhance scat analysis techniques in the laboratory. The study noted that the human-disposed food waste, stable and constant water supply, preserved wild flora and minimal disturbance …

Response of Three Species of Monkeys to Caregiver Use of Species-Typical Behavior
… should be considered. Chimpanzees, gorillas, New World monkeys, and Old World monkeys responded positively to interactions with caregivers. Some species showed increased affiliative behaviors and decreased abnormal or self-directed behaviors after interactions. These studies showed that caregivers …

Capuchin monkey and the Caatinga dry forest : a hard life in a harsh habitat.
… for survival. Albeit a simple question, it unfolds into more complex questions regarding how ecological pressures might drive brain evolution and intelligence in primates. Although there is no "best" hypothesis to explain the evolutionary brain enlargement in higher primates, fine-grained …

Should I stay or should I go? Hormonal and demographic correlates of natal dispersal in a population of wild vervet monkeys
… be costly. Male dispersal is most common among Old World monkeys, but is poorly studied due to the difficulty of following dispersing individuals. Even fewer studies have attempted to explore the hormonal correlates of dispersal owing to the difficulties of obtaining sufficient faecal samples of …

What’s in a Tooth? Signals of Ecogeography and Phylogeny in the Dentition of Macaques (Cercopithecidae: Macaca)
… widespread and ecologically successful Old World primate genus, the macaques (Cercopithecidae: Macaca). To this end, the relationship between geography, ecology, phylogeny, and phenotypic variation among macaques was investigated. Constraints to phenotypic variation – and thus evolution …
