Abstract

Abstract. Infanticide, the intentional killing of conspecific infants, has been observed widely in mammals, including squirrels. Several ground squirrels revealed this behavioral anomaly, yet no report has been published on the flying squirrels. We report an observation of killing an infant of the particolored flying squirrel (Hylopetes alboniger) by a conspecific adult intruder in Satchari National Park of northeast Bangladesh. Among the several adaptive explanations for infanticide, our observations point to sexual selection in males that confers a competitive advantage by making females receptive. However, the resource competition hypothesis, where the intruder's offsprings gain access to resources as a result of the infanticide cannot be ruled out. Extensive studies are needed to document the extent of infanticide in flying squirrels and their adaptive significance.

孟加拉东北部森林颗粒鼯鼠(Hylopetes alboniger)杀婴行为观察
摘要杀害婴儿,即故意杀害同种婴儿,在包括松鼠在内的哺乳动物中已被广泛观察到。几只地松鼠揭示了这种行为异常,但还没有关于飞松鼠的报告发表。我们报道了在孟加拉国东北部的萨查里国家公园,一只同种成年入侵者杀死了一只特殊飞鼠(Hylopetes alboniger)的婴儿。在对杀婴的几种适应性解释中,我们的观察指出,男性的性选择通过让女性接受而赋予竞争优势。然而,不能排除资源竞争假说,即入侵者的后代因杀婴而获得资源。需要进行广泛的研究来记录飞松鼠杀婴的程度及其适应意义。
