首次发现版纳鱼螈冬眠洞穴

2012年12月至2013年2月对版纳鱼螈(Ichthyophis bannanicus)的冬眠进行初步研究,发现5条版纳鱼螈(包括成体和亚成体)在4个冬眠洞穴内冬眠,其越冬地选择在距离水源不远的溪流岸边或者平缓的山坡,能够自行打洞或者利用其他动物废弃的洞穴进行冬眠。版纳鱼螈主要是以单栖的方式冬眠,身体呈S形或者圆形。

Firstly Discovered the Hibernation Cave of Ichthyophis bannanicus in the Field

Based on preliminary observation of Ichthyophis bannanicus carried out from December 2012 to February 2013, we discovered for the first time five I. bannanicus (including adult and sub-adult) in hibernation and four hibernation caves in the filed. The study results showed that I. bannanicus tend to choose banks of stream and gentle hillside near water sourse (distance to stream: 0.51-5.23 m) as their overwintering place. The hibernation caves were simple, with the depth from 22.3 cm to 85.4 cm. During overwintering period, they can tunnel or use caves abandoned by other animals. They generally hibernate alone with their body in S or circular shape. In the last, we measured body characters of the five I. bannanicus.
