太行山猕猴王屋-1群的种群动态

种群动态是种群生态学研究的核心问题.为深化对太行山猕猴种群生态学的认识,本研究以栖息于太行山猕猴国家级自然保护区天坛山管护区的太行山猕猴王屋-1群(WW-1)为对象,基于野外观察记录,并结合访问调查和文献查阅,整理分析了该群2002年12月至2015年12月的种群参数、个体扩散模式和种群增长方式等.结果显示:1)WW-1群由2002年12月的14只增长至2015年12月的106只;2)WW-1群平均出生率为每年每只成年雌性生产(0.56±0.23)只婴猴,婴猴(1岁)平均死亡率为10.8%±21.0%;3)WW-1群表现出明显的偏雄(male-biased)的个体扩散模式;4)种群呈指数式增长(Nt=13.32×e~(0.153 1(t-2002))),瞬时增长率为0.153 1.

Population dynamics of troop Wangwu-1 taihangshan macaques in Mt.Taihangshan area,Jiyuan,China

Population dynamic is the core topic of population ecology.In order to deepen the understanding of population ecology of Taihangshan macaques,this study surveyed the population parameters,dispersal,and population growth of a freeranging troop(WW-1)of Taihangshan macaques inhabiting in Mt.Wangwu of Taihangshan Macaque National Natural Reserve.During December 2002 to December 2015,we collected the data with the methods of field observation,survey,and publications.The results shows:1)troop size increased from 14 individuals by December 2002 to 106 individuals by December 2015;2)the average birth rate was(0.56±0.23)infants per adult female per year,and the infant(< 1 year old of age)mortality was 10.8%±21.0% on average;3)WW-1 exhibited a pattern of male-biased dispersal;4)the population growth of WW-1 was as exponential(Nt=13.32×e~(0.153 1(t-2002))),and the instantaneous growth rate was 0.153 1.
