短尾猴种群生态学研究Ⅰ．短尾猴种群动态及分析

STUDIES ON POPULATION ECOLOGY OF TIBETAN MONKEYS(MACACA THIBETANA)Ⅰ.POPULATION DYNAMICS AND ANALYSIS OF TIBETAN MONKEYS

本文分析了１９８６－１９９２年安徽黄山短尾猴鱼鳞坑群种群动态。结果表明，在研究期间该群以年平均１０．３％的速度增长，年平均产仔率６６．９％。疾病导致个体死亡和雄猴的迁入与迁出对种群数量变化有一定影响。

A field troop of Tibetan monkeys(Macaca thibetana)at Mts.Huangshan(E 118°10’,N30°29’),Anhui province,was investigated from 1986 to 1992.Analysis of popula-tion dynamics shows the individual numbers of this troop was 10.3%of average annualincreased (see table 1).Annual average natality was 66.9%(see table 2).The natalitywas relatively stable in the seven years.Disease seems to be a main cause of death.Thechange of population size in this troop were also affected by male monkeys immigrationor emigration.
