Provisioning And Its Effects On The Social Interactions Of Tibetan Macaques (Macaca Thibetana) At Mt. Huangshan, China, Brianna I. Schnepel Jan 2015

Provisioning And Its Effects On The Social Interactions Of Tibetan Macaques (Macaca Thibetana) At Mt. Huangshan, China, Brianna I. Schnepel

All Master's Theses

The dispersal patterns of food resources has a significant effect on the composition of primate groups and social interactions within those groups. Humans often alter the dispersal of food. Non-humans often use affiliative behaviors to elicit tolerance or support from other group members. I investigated whether provisioned food resources alter the social interactions and group dynamics of Macaca thibetana. All-occurrence sampling and scan sampling were used for data recorded by camera traps. Trail-cameras were placed at six locations that contain natural and human food resources and recorded 60-second videos. Social behavior and proximity of the monkeys were recorded. I …


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, …


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, …
