Collective Decision Making In Tibetan Macaques: How Followers Affect The Rules And Efficiency Of Group Movement, Amanda Rowe
All Master's Theses
Primate societies must undergo successful collective decision making during group movement to stay cohesive and provide the ecological and evolutionary benefits of sociality. This study investigates how a fan structure facilitates successful group movement in the YA1 group of Tibetan macaques (Macaca thibetana) at Mt. Huangshan National Reserve in Anhui, China. We used structural equation modeling (SEM) to determine the relative influences of sex, age, maternal kinship, dominance, and social network centrality on the number of fans (consistent followers) an individual had, and the number of group members an individual was a fan of (fandom). SEM revealed that …

I gathered information on their movements and social networks through all-occurrence, focal and scan sampling.

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, …
