神农架川金丝猴投食群0-6月龄的母亲照顾行为

Infant-care behaviors exhibited toward 0-6 month-old infants of a provisioned group of Sichuan snub-nosed monkey in Shennongjia National Nature Reserve

与其它哺乳动物相比,灵长类动物的一个最典型的特征就是婴儿在出生之后完全没有独立生活能力,处于这个时期的动物非常软弱（Nicolson,1987）。在这段发育期内,必须依靠社群内成年或亚成年个体的照顾才能顺利存活,尤其是来自母亲的照顾,母亲通过哺乳提供给它们成长所需要的营养,并通过限制行为实施保护,同时教会婴儿基本的生存技能,

Detailed observations of female primate infant care are important for clearly understanding maternal behavior and the behavioral development of the infant.From March to November 2009,field observations of maternal behaviors toward 0-6 month-old infants of a provisioned Sichuan Snub-nosed monkey group were conducted using objective animal sampling,point-recording and whole event recording methods at Dalongtan,Shennongjia National Nature Reserve of Hubei Province.Of all of the mother-infant behaviors observed maternal carrying behavior occurred most frequently,followed by breast-feeding,hugging,grooming,and restraining.Restraining behavior between provision and non-provision periods was significantly different and reached a higher peak in 2-and 3-month-old infants.Maternal carrying,hugging,and grooming behaviors gradually decreased as infants aged.Maternal care behaviors in this provisioned group of Snub-nosed monkey were similar to those in other populations and no independent behavioral evolution resulted from geographical segregation between these populations.
