The Research On The Influence Of Captivity On Social Activity Of Sichuan Golden Snub-nosed Monkeys(Rhinopithecus Roxellana)

Social behavior refers to the interactions between the individuals with social relationships. The non-relative cooperation in society only occurs based on identify each other and a large number of chances to exchange fitness. The research on the social behavior of non-human primates can help illustrating the sustainability stabilization and the evolution mechanism of human social structure. Sichuan snub-nosed monkeys (Rhinopithecus roxellana) are one of the protected animal in China and a small part of them are reared and cared in cages while the most individuals of roxellana living in wild. Whether cage environment would put a limit on social activity or not? Few work have being done to anwer that question.We collected data of activity and positional behavior from wild and captivity populations by Focal-animal instantaneous point-sampling methods, and defined five diurnal activities and ten postitional behavior patterns. The results indicate as follows:(1).the environment of captivity have no influence on the basic social behavior of reproduction and it only lay restriction on the opportunity to non-relative cooperate of the senior social attributes;(2). Since the plenty of food and nutrition, the captivity individuals are more active than the wild ones in movement behavior (F=3.274, p=0.041),and the result which 4 positional behaviors(jump, U=115,p=0.013; climb, U=73,p=0.000; Suspension move, U=138, p=0.028; Suspension, U=138, p=0.028) are obviously higher than the wild individuals' further verified our conclusion that captivity individuals are more active;(3). the research shows that the preference of social behavior between genders and ages are significant:adult male aggressing, threatening most (?~2=16.221, p=0.000); adult female allogrooming most(LSD test:compared with adult male, p=0.018; compared with nonage, p=0.048); nonage individual most spend on social playing(?~2=12.932, p=0.002), mounting(?~2= 6.046, p=0.049), being aggressed and eluding(LSD test:compared with adult male p= 0.038) activities.
