摘要

喜马拉雅水鼩(Chimarrogale himalayica)广泛分布于南亚和东亚。然而,由于喜马拉雅水鼩躲藏在河岸常绿林的溪流水下等难以捉摸的觅食技巧,人们对它们的分布和生态还没有正确的认识。该物种有限的栖息地和食物需求使其研究具有挑战性。由于该物种的栖息地更容易受到干扰,人为压力导致的栖息地丧失是主要问题。该物种的旧记录很少,在全球特定地点的调查中也只有零星报告,这些地点构成了该物种目前的分布范围。虽然该物种在印度分布零散,但我们首次报告了 Chimarrogale himalayica 在溪流中试图捕食层叠蛙 Amolops sp.时的半水生觅食行为的视频图像证据。我们的发现仍然是独一无二的,它为我们在梅加拉亚邦詹蒂亚丘陵的新记录所提供的有关该物种扩展分布范围的信息增添了新的内容,并有助于进一步了解鼩鼱的觅食行为。

New Distribution Record of Himalayan Water Shrew Chimarrogale himalayica (Gray, 1842) Soricomorpha: Soricidae and its Attempt to Feed on a Cascade Frog Amolops sp. from Jaintia Hills, Meghalaya, India.

The Himalayan water shrew, Chimarrogale himalayica, is widely distributed in South and East Asia. However, their distribution and ecology are not properly understood due to the elusive foraging techniques like hiding underwater in streams of riparian evergreen forests. The restricted habitat and food requirement of the species makes it challenging to study. Habitat loss due to anthropogenic pressure is the major concern as the species is more prone to habitat disturbances. The old records are sparse and are sporadically reported in surveys from specific locations worldwide forming its current distribution range. Although the species has a scattered distribution in India, we report the first video graphic evidence of Chimarrogale himalayica's semi-aquatic foraging behavior while attempting to feed on a cascade frog Amolops sp. in a stream. Our finding remains unique and adds information on the extended distribution range of the species from our new record in Jaintia hills, Meghalaya, and helps further understand the shrews’ feeding behavior.
