Acoustic Analysis Of Nomascus Gibbon Songs As A Potential Measure Of Current Health Status, Caroline Rowley
All Master's Theses
Post-release monitoring is vital to the rehabilitation process. Gibbons offer a unique challenge, as they are notoriously difficult to follow through the forest, but their duets offer a non-invasive window into their lives. The aim of this project is to create a method that will evaluate the health of rehabilitated and released gibbons through acoustic analyses. Gibbon duets are in part genetically determined, but learning may play a role in song development. Additionally, songs may indicate resource holding potential, and are vital to acquiring mates and producing offspring. Captive-raised gibbons are often denied the experience of co-singing with their parents, …

The Social Behavior Of Rehabilitated Spider Monkeys (Ateles Geoffroyi), Anthony Denice
All Master's Theses
The welfare of captive primates in laboratories, sanctuaries, and zoos is affected by various aspects of their environments. Although space restrictions increase aggression and stress-related behaviors in most captive animals, primates show diverse mechanisms for displacing stress and mitigating conflict. Many primates, including wild spider monkeys (genus Ateles), use these mechanisms flexibly to cope with social and environmental stressors. I investigated whether or not captive black-handed spider monkeys (Ateles geoffroyi) use behavioral strategies to cope with potential stressors in captivity. In particular, I tested whether an affiliative or avoidant strategy was used in response to changes in …
