Group Differences In Mother-Infant Macaca Fascicularis Behavior, Parasite Load, And Body Condition Within An Anthropogenically Altered Forest, Elizabeth M.C. Coggeshall Jan 2020

Group Differences In Mother-Infant Macaca Fascicularis Behavior, Parasite Load, And Body Condition Within An Anthropogenically Altered Forest, Elizabeth M.C. Coggeshall

All Master's Theses

This study aimed to establish preliminary health and behavioral data, as well as understand group variation for a large population of Macaca fascicularis individuals within an anthropogenically altered monkey forest. A parasitic analysis of 40 mother and infant individuals showed that M. fascicularis carried 13 different parasitic taxa, and that there was parasitic variation between groups. Body condition scores were determined using a newly created and adapted body condition scale from 146 sampled mother macaques. Body condition scores were significantly different between groups, specifically the pond group when compared to the three other groups. Mother-infant behavioral differences were seen between …


Effect Of Group Size On The Activity Budget Of Two Captive Chimpanzees (Pan Troglodytes), Kaeley Sullins Jan 2019

Effect Of Group Size On The Activity Budget Of Two Captive Chimpanzees (Pan Troglodytes), Kaeley Sullins

All Master's Theses

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 facility with new social partners, can impact each individual chimpanzee’s welfare. By tracking each chimpanzee’s activity budgets, managers can assess welfare and make improvements or adjustments if necessary. I looked at the activity budgets of two captive chimpanzees after the death of a group member and the two chimpanzees’ subsequent relocation to a novel, more socially …


The Effect Of Sound On Captive Chimpanzees (Pan Troglodytes), Grace Coffman Jan 2019

The Effect Of Sound On Captive Chimpanzees (Pan Troglodytes), Grace Coffman

All Master's Theses

Sound exposure can have detrimental physiological and psychological effects on humans, but effects on nonhuman 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 collection assessed for frequency of behavior and correlations between chimpanzee behavioral categories, arousal level, and decibel level. Agonistic behavior occurred more frequently in the highest decibel level category. There was a positive correlation between decibel level and arousal level. These findings suggest the need for increased …


Response Of Three Species Of Monkeys To Caregiver Use Of Species-Typical Behavior, Lillian Anna Stolar Jan 2018

Response Of Three Species Of Monkeys To Caregiver Use Of Species-Typical Behavior, Lillian Anna Stolar

All Master's Theses

Caregivers are a primary part of captive monkey environments. When addressing psychological well-being of captive nonhuman primates, social environment 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 can affect the behavior of nonhuman primates. Caregivers are underutilized as a source of social interaction for captive nonhuman primates. Utilizing species-typical behaviors during interactions, caregivers and nonhuman primates can communicate and interact in different ways that may be beneficial to both caregiver and …


Enrichment Use & Social Interactions In A Mixed-Species Enclosure Of Sumatran (Pongo Abelij) & Bornean Orangutans (P. Pygmaeus) & Northern White-Cheeked Gibbons (Nomascus Leucogenys), Emily Veitia Jan 2017

Enrichment Use & Social Interactions In A Mixed-Species Enclosure Of Sumatran (Pongo Abelij) & Bornean Orangutans (P. Pygmaeus) & Northern White-Cheeked Gibbons (Nomascus Leucogenys), Emily Veitia

All Master's Theses

Enrichment is an aspect of captive husbandry that has been shown to positively impact animals’ well-being and can be designed to encourage species-typical behaviors, such as foraging and arboreality. Enrichment can include housing together multiple compatible species. Orangutans are sympatric with siamangs and agile and Bornean gibbons, so several zoos house these four Asian ape species in the same enclosure, in part, as social enrichment. In my study, I observed enrichment use and social interactions in a mixed-species enclosure at the Oregon Zoo, which housed two Sumatran (Pongo abelii) and two Bornean (P. pygmaeus) orangutans with …


Female Social Connectivity Through The Leadership And Movement Progression Of Tibetan Macaques At Mt. Huangshan, China, Gregory P. Fratellone Jan 2015

Female Social Connectivity Through The Leadership And Movement Progression Of Tibetan Macaques At Mt. Huangshan, China, Gregory P. Fratellone

All Master's Theses

The present study investigates the leadership and progression of collective movements of Tibetan macaques (Macaca thibetana) found in Mt. Huangshan, China. I gathered information on their movements and social networks through all-occurrence, focal and scan sampling. I hypothesize that high-ranking females lead more collective movements than males as they have highly structured social bonds. I also predict that movements weighted by female presence are more efficient as societies are matrilineally structured and females are more socially connected. There were a total of 128 successful collective movements recorded over a 2-month period. There was no significant effect of sex, …
