Infant-Maternal Behaviors During Non-Maternal Infant Handling Interactions In Captive Long- Tailed Macaques (Macaca Fascicularis), Kristy Abney Jan 2023

Infant-Maternal Behaviors During Non-Maternal Infant Handling Interactions In Captive Long- Tailed Macaques (Macaca Fascicularis), Kristy Abney

All Master's Theses

The main caregiver of an infant Long-tailed macaque (Macaca fascicularis) is their mother. However, mothers often allow infant-handling interactions with other individuals in their group. While there are many hypotheses to explain the infant-handling phenomenon, there are few systematic investigations of how mothers respond to non-mother infant-handling interactions. At Alpha Genesis Inc., I conducted 33 focal follows for each mother-infant dyad (N = 10) over an eight-week period on captive macaques to determine if infant behaviors during infant-handling interactions resulted in mothers interrupting the interaction; if mothers were more likely to interrupt infant-handling interactions when infants showed signs …


Examining The Function Of Stone Wrapping Behavioral Pattern In Balinese Long-Tailed Macaques (Macaca Fascicularis), Patricia Mitchell Jan 2022

Examining The Function Of Stone Wrapping Behavioral Pattern In Balinese Long-Tailed Macaques (Macaca Fascicularis), Patricia Mitchell

All Master's Theses

Long-tailed macaques (LTMs, Macaca fascicularis) have multiple stone handling (SH) patterns that vary in form and complexity across different populations, but little is known about the group of Balinese LTM’s motivation to wrap stones in the Monkey Forest of Ubud, Indonesia. This study focuses on whether the SH pattern, wrap (WRP), is an object play behavior with the potential of becoming a more functionally complex behavior (e.g., tool use). SH sequences were collected using all-occurrence and focal sampling and examined using the program Behavioral Observation Research Interactive Software (BORIS). In total, 322 minutes of footage were reviewed for both stones …


Effects Of A Voluntourism Experience On Perceptions And Attitudes Toward Environmental Sustainability And Science, Mireille Gonzalez Jan 2019

Effects Of A Voluntourism Experience On Perceptions And Attitudes Toward Environmental Sustainability And Science, Mireille Gonzalez

All Master's Theses

The current study explored the impact of a volunteer tourism experience at a community-based conservation (CBC) organization on volunteer perceptions, attitudes, and values toward conservation, the environment, and science. The Madagascar Research and Conservation Institute (MRCI) is a CBC organization that utilizes volunteers as a data collection resource and workforce for conservation and community outreach initiatives. The current study analyzed data from volunteer experience evaluations (VEE), which included pre- and post-experience self-report surveys comprised of qualitative and quantitative response sections, completed by 45 voluntourists over a three-month span. The quantitative findings indicate that the voluntourist experience improved participants’ self-reported attitudes …


Sign Modulation By Chimpanzees To Produce Interrogatives, Kailie Dombrausky Jan 2018

Sign Modulation By Chimpanzees To Produce Interrogatives, Kailie Dombrausky

All Master's Theses

Native signers of American Sign Language produce interrogatives by holding signs for an extended duration while employing the questioning look. The questioning look is defined as raised eyebrows, a tilted head, and direct eye contact maintained for the duration of the utterance. Chimpanzees who communicate using signs have demonstrated modulation of signs including held sign, raised brow, and eye gaze. The present study used archived video data to compare the duration of signs when the chimpanzees did or did not employ the questioning look. In both single and multi-sign utterances, the chimpanzees held their signs for a mean of 0.6 …


Re-Evaluating Captive Chimpanzee “Dominance”: Dominance Hierarchy And Chimpanzee-Caregiver Relationships At Chimpanzee Sanctuary Northwest, Jake Funkhouser Jan 2018

Re-Evaluating Captive Chimpanzee “Dominance”: Dominance Hierarchy And Chimpanzee-Caregiver Relationships At Chimpanzee Sanctuary Northwest, Jake Funkhouser

All Master's Theses

This thesis is composed of two journal-ready articles and an accompanying appendix with additional data and interpretation. Overall, this thesis describes and statistically analyzes dominance relationships in two nonhuman primate groups with novel methods, possible correlations between dominance and testosterone, and uncovers the 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, context-dependent dominant structures (agonistic competitions, lack of agonism, privileged role, priority access to resources), the reliability of …


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 …


Behavioral Differences Between Urban And Rural American Crows (Corvus Brachyrhynchos), Carolina Montenegro Jan 2017

Behavioral Differences Between Urban And Rural American Crows (Corvus Brachyrhynchos), Carolina Montenegro

All Master's Theses

The consequences of transforming a natural environment into a human-modified environment (i.e., urbanization) on wildlife has long been a topic of concern, but has been hampered by a lack of empirical evidence focused on animal behavior. The current study was designed to explore behavioral differences between urban and rural American crows (Corvus brachyrhynchos) by installing baited perches in urban and rural settings in Kittitas County, Washington. In order to observe differences in urban and rural crow behavior to approach or avoidance-oriented stimuli, perches included custom cameras and audio equipment that alternated between periods of playing crow calls or …


Javan Gibbon (Hylobates Moloch) Non-Vocal Social Communication And Gesture Use With Conspecifics, Melanie Bell Jan 2015

Javan Gibbon (Hylobates Moloch) Non-Vocal Social Communication And Gesture Use With Conspecifics, Melanie Bell

All Master's Theses

I explored gestures used by captive Javan gibbons (Hylobates moloch) at the Gibbon Conservation Center (Santa Clarita, CA). I hypothesized that a sender gibbon’s gesture modality would vary with the recipient gibbon’s attentional state and the sender would be equally likely to use all modalities (tactile, visual, actions, and facial expressions) when the recipient was attending (facing the sender), but would use more tactile gestures and actions when the recipient was non-attending (oriented away from the sender). I collected data from 10 individuals using all-occurrences sampling and an ethogram to score behaviors from video recordings. In 1,143 interactions, …


The Public Perception Of Enrichment For Captive Animals, Elizabeth Marie Webb May 2007

The Public Perception Of Enrichment For Captive Animals, Elizabeth Marie Webb

All Master's Theses

The effects of providing participants with educational information on enrichment as measured by the looking time at and ratings of zoo photographs were examined. One hundred and seventeen participants viewed photographs of zoo exhibits, 10 from each of the following categories: artificial exhibit with artificial enrichment, artificial exhibit with naturalistic enrichment, naturalistic exhibit with naturalistic enrichment, and naturalistic exhibit with artificial enrichment. Participants rated the photographs on exhibit aesthetic appeal, perceived animal happiness, and effectiveness of the enrichment. Pre- and posttest ratings of the importance of zoo roles were also collected. Results showed support for the hypothesis that participants provided …
