Population Dynamics of Japanese Monkeys with Special Reference to the Effect of Artificial Feeding

摘要: Population dynamics of Japanese monkeys (Macaca fuscata) have been studied at Mt. Ryozen, central Japan, between 1969 and 1980. The troop had artificially fed until August 1973 and, since then, has living in its natural habitat without artificial feeding. Increase body weight, primiparous age, age-specific natality, survivorship mortality, population biomass growth rate, age disappearance young males were compared the two study periods, with Comparison parameters each period was also done social classes, peripheral. As shown, table VII, it revealed that feeding an important factor furthermore, this effect mainly on kin-groups class troop. In most showed almost same figure for peripheral classes.
