A Study On The Competition And Cooperation Among The Multi - Female Unit In Jinling Monkey Society In Qinling

Previous studies of Sichuan snub-nosed monkey (Rhinopithecus roxellana) mainly focused on the relationship between individuals within the OMU, while relations between OMUS involve less. However, Sichuan snub-nosed monkey community is made up of a number of OMU. When herdmove in a certain direction, The OMU will closely follow. In addition to meet their predators resident males from different OMUs will unite to defense. Between different OMU both cooperation also has competition. What makes different OMU share in feeding and unite to mutual defense? How to build defense cooperation is the key point of this research. This research topic we divided artificially through the hurl food field specific geometry of feeding plaque, to carry out the simulation of Sichuan golden monkey in the experiment of the feeding status under the natural conditions. Experiment 1,3:the uniform distribution of food plaques; Experiment 2: food patches concentration distribution. By 2 min scanning recording, recorded every individual’s food patches; by all events recording collected the Aggression yield and replace behavior between OMUS. By comparing the different seasons; different food plaque distribution. The OMUS behavior changes, Combined with behavior and molecular techniques related to a more comprehensive explanation of the relationship between the OMU. The results showed:1, the OMU of Sichuan golden monkey groups at different times will take different strategies to deal with, when it is in the lack of food resources, against fierce competition between the OMU. In experiment 2times food patches concentrated distribution changes made OMUS against competition, Lower level OMU facing the pressure of food resources and leave the large group. In food resources enough environment, Between the OMU against the weaker competition, In experiment 2 condition left lower ranks of OMU back in large groups.2, in the environment of lack of food resources the dominance relationships between OMUS in Qinling Mountains were strong. Dominance relationships on the stability of the community and communication between the OMU behavior plays a leading role, and since the attack degree of conflict between OMU community level structure more tend to be guarded; Experiment 3 condition less conflict between OMU, dominance hierarchyis not obvious, the dominance relationships were not strong.3, through the OMU main genetic relationship between the male and represents the OMU adult female relatives and share food between different OMUs close to index correlation analysis:the relationship between the OMU actions has no effect on contact and communication.
