基于红外相机视频的猪獾交配行为观察
|
摘要
<正>动物交配的首要功能是雄性向雌性传送精子,其机制的进化是繁殖生物学的核心问题,是理解动物婚配制度和性选择的关键(刘晓明等,2002)。在长期的自然进化过程中,物种为了最大限度地提高自身的适合度而形成了一系列的繁殖对策和生存对策(殷宝法等,2003)。猪獾(Arctonyx collaris),隶属于鼬科(Mustelidae),近危(NT)等级(蒋志刚等,2016),穴居夜行性,性情孤僻,常独居。郑生武等(1988)认为猪獾在雌兽产仔
Mating behavior of the Hog-badger(Arctonyx collaris) was recorded on 463 videos(totally 8053 s) taken with auto-trigger cameras between March 13 and May 13, 2017 in Jiangxi Wuyishan. Male followed and guarded the female for several hours before mating. One mounting behavior, and three mating behaviors were observed from 01:55 to 08:49 on April 18. The durations of mating behaviors lasted for 731 s, 1 690 s and 1 494 s, respectively. Based on these observations, we found(1) mating behavior was controlled by the female, including obvious sexual solicitations;(2) female can mate more than one time within one estrous cycle;(3) quickly and repeatedly pumping and inserting behavior was observed in male during mating.
