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 …


Use Of Vertical Enclosure Space And Species-Typical Locomotion By A Rehabilitating Spider Monkey (Ateles Fusciceps), Jake Funkhouser Jan 2017

Use Of Vertical Enclosure Space And Species-Typical Locomotion By A Rehabilitating Spider Monkey (Ateles Fusciceps), Jake Funkhouser

Undergraduate Honors Theses

With wild spider monkey populations in decline, investigations contributing to captive welfare, and successful rehabilitation and reintroduction knowledge is increasingly pressing. Quantifying and analyzing the appropriateness of naturalistic enclosure designs to foster species-typical behaviors is an effective way to address both of these needs. This study investigates enclosure space use, vertical space preference, substrate use, positional/postural modes, and interactions with human caregivers of a wild-caught, pet-trade rehabilitant Columbian black spider monkey (Ateles fusciceps rufiventris, N = 1). Video data collected daily from August to October 2015 via focal animal sampling (from 08:00 to 10:00) at Alouatta Sanctuary, Panama …
