摘要

有关剥夺后代食物的母性行为的资料很少，但观察到一些日本猕猴（Macaca fuscata）的母亲会从后代手中抢走食物并吃掉。本研究调查了有食物供给、自由活动的日本猕猴的母性抢食行为及其对后代生长的影响。与同龄婴儿摄入的固体食物量相比，按干重计算，母亲从其后代身上抢走的食物量估计为51.2%。受影响婴儿的体重增长低于平均水平。这项研究表明，MFSB可能是一种病态行为，并首次详细描述了父母在动物身上的剥削行为。

Maternal exploitation: impact of maternal food snatching behaviour on the growth of their offspring in Japanese macaques.

There is little information on maternal behaviour that deprives offspring of food, but some Japanese macaque, Macaca fuscata, mothers have been observed to snatch food from their offspring and eat it. This study investigated maternal food snatching behaviour (MFSB) and its impact on the growth of their offspring in provisioned, free-ranging Japanese macaques. The amount of food a mother snatched from her offspring was estimated to be 51.2% by dry weight compared to the amount of solid food an infant of the same age took in. Body mass growth of affected infants indicated a below-average mass gain. The study suggests that MFSB might be a pathological behaviour and provides the first detailed account of parental exploitation in animals.

期刊介绍： Primates is an international journal of primatology whose aim is to provide a forum for the elucidation of all aspects of primates. The oldest primatological journal, Primates publishes original papers that advance the scientific study of primates, and its scope embraces work in diverse fields covering biological bases of behavior, socio-ecology, learning and cognition, social processes, systematics, evolution, and medicine. Contributions relevant to conservation of natural populations and welfare of captive primates are welcome. Studies focusing on nonprimate species may be considered if their relevance to primatology is clear. Original Articles as well as Review Articles, News and Perspectives, and Book Reviews are included. All manuscripts received are initially screened for suitability by members of the Editorial Board, taking into account style and ethical issues, leading to a swift decision about whether to send the manuscript for external review.
