Abstract: | Male intertroop transfer among Japanese macaques (Macaca fuscata) often coincides with the mating season. However, no necessary connection exists between mating by newly arrived males and
whether they join a troop—visitors often mate, and males that join troops may show little mating success. On the other hand,
intertroop transfer often coincides with major events in the developmental and social life history of males, such as the attainment
of sexual maturity and full adult body size or rise in dominance rank. Thus, intertroop transfer may reflect age-specific
behavioral patterns in which males maintain a position in the age-rank structure of troops, where the rank acquired in a new
troop is partially determined by age. |
