Abstract: | The present study compares the behavior of old female Japanese macaques (Macaca fuscata) with that of their full adult daughters in a free-ranging group, with respect to dominance and seasonal changes. Old mothers
(21 to 25 years old) spent more time resting and alone than did their middle-aged adult daughters (10 to 17 yr old). However,
the number of skin-related animals in proximity to the subject females, did not differ between mothers and their adult daughters.
Mothers maintained proximity to more non-kin-related immature animals in the mating season than did their adult daughters,
perhaps to avoid sexual aggression from males and to reduce the loss of body temperature in the cold. Dominance rank clearly
influenced the social interactions of old mothers: high-ranking mothers interacted with more non-related adult females and
immature animals than did low-ranking mothers, indicating that old age does not decrease the attractiveness of high-ranking
animals. |
