摘要
为探索人工补加食物对川金丝猴种群发展的作用,于2006年1月至2007年8月采用焦点动物取样法和行为取样法对湖北神农架大龙潭金丝猴群体结构和繁殖情况进行研究。猴群于2007年6月22日开始出现社会单元主雄替代现象,持续至8月10日替代完成。替代前群体共有45只个体,构成3个一雄多雌单元和1个全雄单元;替代后群体数量为43只,减少2只成年雄性,构成4个一雄多雌单元和1个全雄单元,替代后未发生新生小猴消失现象。2006和2007年共新生小猴11只,全部存活。结果揭示人工补加食物降低了投食群个体饥饿死亡的可能性,提高了新生婴猴存活率,人工投食是促进川金丝猴种群发展的有效途径。
In order to confirm the positive effects of food supplying on population development of Sichuan snub-nosed monkey (Rhinopichecus roxellana ), the colony structure and yearly reproduction output were studied on a provisioned group by focal animal sampling and behavior sampling at Hubei Shennongjia Nature Reserve between January 2006 and August 2007. On June 22 of 2007, a fight for the position of resident-males burst and lasted to August 10 of 2007. Before the event happened, there were 45 individuals in this provisioned group with 3 one-male units and 1 all-male unit, while there were 43 individuals with 4 one-male units and 1 all-male unit after the resident-male takeover with 2 adult males disappeared. No infant loss was found during and after the takeover process. All of the 11 new born infant monkeys survived in 2006 and 2007. The results showed that food provision lowered the death possibility of starvation and increased the survival rate of infants. Food provision is an effective way to promote population development in snub-nosed monkey at Shennongjia Nature Reserve of Hubei Province, central China.
