穴居性动物的洞穴对其生存有着重要的影响。为了解喜马拉雅旱獭(Marmota himalayana)利用洞穴的特征及其生态意义,于2017年5月至10月以及2018年4月至5月在四川省阿坝州若尔盖县班佑乡多玛村对30对喜马拉雅旱獭繁殖对所利用的洞穴进行了定量研究。按照当年被频繁利用的洞穴(夜宿洞与繁殖洞)与临时利用的洞穴1∶2的比例取样,共测量了90个洞穴的7个物理特征参数,比较了不同类型洞穴的物理特征差异。结果表明:(1)当地喜马拉雅旱獭利用洞穴外径的长轴和短轴分别为59.3 ±21.9 (16 ~100) cm和45.8 ±20.5(18 ~100) cm,内径的内横径和内竖径分别为24.4 ±4.0 (16 ~39) cm和19.7 ±3.5 (15 ~39) cm;(2)洞...

Dens play an important role in the survival of cavernicolous animals. To explore the characteristics and ecological significance of Himalayan marmot (Marmota himalayana) dens, we surveyed the dens of 30 breeding pairs of Himalayan marmots at Duoma Village, Zoige County, Aba Prefecture, Sichuan Province from May to October 2017 and April to May 2018. Ninety dens that were extensively used (sleeping dens and breeding dens) and temporarily used (temporary dens) were selected, and seven physical characteristics of each den were measured to analyze ...
