摘　　要：藏猕猴（Ｍａｃａｃａｔｈｉｂｅｔａｎａ）雄－婴行为的补充数据收集于１９９７年１～９月、覆盖了整个出生季节和半个交配季节。分别用１分钟点取样和５分钟事件取样收集雄婴照料（怀抱＋接近）和雄－婴－雄三边作用（ｔｒｉａｄ）的数据。焦点动物为两个猴群中的８个婴儿。数据处理结果表明：①雄－婴照料集中在４５～１８周龄，而２０周龄内的婴儿平均有７９％的时间受到雄性照料（雄９６％，雌５６％）；②雄性婴儿较雌性接受的照料偏多，但同性个体间无差异；③雄性照料的强度随行为者社会等级的升高而增大；④婴儿介入ｔｒｉａｄ的频次与其接受照料的强度正相关。考虑到藏猕猴繁殖单位中非优势雄猴的交配机会极少，结果③、④支持了先前关于性／亲选择介入了藏猕猴雄－婴行为进化的结论。然而，因为结果②不支持严格的“父－子”照料假设，这种介入只具有模糊的统计学意义。Data on male infant social behavior of Macaca thibetana were collected in a period from January to September 1997,covering the whole birth season and the early mating season.One minute point sampling was used for male infant caretak ing (in lap+in proximity),and five minute event sampling for male infant mal e interactions (triads).The observation resulted in:①The infant of 4 5-18 wee ks was caretaken by adult males for 7 9% of its time in early 20 weeks after bi rth (9 6% for males vs.5 6% for females).②The caretaking tended towards male infants,but no differences existed among the same sex of infants.③The intensit y of caretaking increased with the rank of caretakers.④The percent of infant's caretaken time was positively related to the number of triads involved by the in fant.Because the mating opportunity of males is rank dependent,results 2 and 3 imply that sexual/kin selection was involved in the evolution of male infant c aretaking (IMC) in a fuzzy way.
