Abstract

Grooming interactions among female Japanese macaques (Macaca fuscata) were observed and compared between affiliated and unaffilitated non-related pairs, mother and adult female offspring paris, and mother and immature offspring pairs. Unaffiliated (rarely interacting) members of pairs were likely to approach and then groom the other, in contrast to affiliated (frequently interacting) pairs, who more often approached and then solicited grooming from the other. The return receipt of a benefit just given, in the form of reciprocation of grooming, was immediate in non-related pairs. The brief interval between the occurrence of reciprocation facilitated the estimation of receiving as much benefit as was given in the case of rare grooming. However, such was not the case for related pairs. Adult female offspring solicited grooming from mothers more than immature offspring. The findings are discussed with reference to previous theories about the evolution of altruistic behaviour. /// ニホンザルのオトナメス間でおこなわれるグルーミング交渉を観察し、頻繁に交渉を持つ非血縁メスのペア、あまり交渉を持たない非血縁メスのペア、母親と成熟した娘のペア、母親と未成熟のこどものペアの間で比較した。 あまり交渉を持たないペアでは、接近したあと相手にグルーミングをすることが多かったが、頻繁に交渉をもつペアでは、後近したあと相手にグルーミングを催促することが多かった。 非血縁メス間のグルーミング交渉では、グルーミングすることによって相手に与えた利益を、すぐにグルーミングを返してもらうことによって相手から取り戻していた。 グルーミングのやりとりの間隔が短いために、相手とのグルーミング交渉が少ない場合にも、相手に与えた利益と同じだけの利益を相手から受け取れるという予測がしやすくなっていると考えられた。 しかしながら、血縁個体のペアではこのようなやりとりのパターンは見られなかった。 血縁個体間のグルーミングでは、成熟した娘は未成熟のこどもに比べ、母親にグルーミングを催促することが多かった。
