秦岭羚牛的母亲杀婴行为

Observation of mother-perpetrated infanticide in golden takins (Budorcas taxicolor bedfordi)

  • 摘要: 动物群体中非亲缘个体间的杀婴行为常有报道,但父母杀害亲生后代的现象却很少见,尤其是由母亲主导的杀婴行为。本文通过视频录像设备对秦岭羚牛(Budorcas taxicolor bedfordi)生产与哺育行为进行长时间监控,发现3起由母亲主导的杀婴现象。结合早期其他物种的研究结果,我们推测秦岭羚牛的母亲杀婴行为符合母亲操作机制假说(Parental manipulation mechanism),即:母亲会通过主动杀掉不健康的婴儿后代,从而提高对健康后代的照顾投入以及获取更多的生殖机会。此种现象或许是一种适应进化的策略,通过自然选择达到种群稳定和繁荣的目的。本次观察结果带来了更多关于母亲杀婴的思考,这需要我们对圈养和野生种群持续开展研究来解决有关杀婴机制更深层次的科学问题。

     

    Abstract: Infanticide by unrelated individuals is widely reported in the animal kingdom; however, little is known about cases perpetrated by a parent, particularly the mother. This article reports on three cases of mother-initiated infanticide in Qinling golden takins (Budorcas taxicolor bedfordi) recorded from video and camera images. Based on previous reports in other animals, we propose that the infanticide events observed in golden takins were related to the parental manipulation mechanism – i.e., killing an unhealthy infant to allow the mother to invest more care in potentially healthy offspring, and gain more fruitful reproductive opportunities. This appears to be an evolutionary-based selection strategy, whereby a species can prosper and succeed under the challenges of natural selection. However, further studies on both captive and wild populations are required to answer the various questions raised from our observations.
