Abstract:

Dominance hierarchy which influences male reproductive behavior and social behavior, has often been reported in non-human primates. We examined aspects of dominance hierarchy in the Tibetan macaque (Macaca thibetana) at Mt. Huangshan, China. Six adult males were assigned into 3 groups:the dominant group,medial group and subordinate group, respectively, as representing their dominance rank in the YA2 troop at Mt. Huangshan. Social behavior data were collected using focal animal sampling. Our results showed: (1)The dominant group participated most often in bridging behavior; the frequency of sending and receiving bridging behavior was significantly different among different ranks; (2)The subordinate group participated most often in social mount behavior, the frequency of sending and receiving social mount behavior was significantly different among different ranks;(3)The dominant group received present behavior the most often, while the subordinate group was most likely to present. Frequency of sending present behavior also varied significantly among different ranks, but there was no significant difference in receiving present behavior among the different ranks; and (4) Frequency of shaking tree behavior was significantly different among the different ranks. We speculate that amicable behaviors reflect the social dominance rank and are an important way to sustain social stability.
