摘要
A wild Japanese macaque troop decreased in size because the birth rate dropped and infant mortality increased. In the 1989 mating season, the last male left the troop, and the remaining two females joined a neighboring troop. Thus, the troop ceased to exist as an independent troop. A lower limit to troop size may exist, below which a troop cannot effectively defend its range, forcing the females to join a larger troop. (C) 1994 Wiley-Liss, Inc.
