The Transbaikal zokor () is a dominant rodent distributed in the meadow steppe of Inner Mongolia in northern China. Due to long history of evolution in subterranean environment, the zokor has an adaptive behavior: sealing burrow entrances. When a burrow is damaged, exposed entrances appear, and within a relatively short time, the zokor would be active in sealing the entrances to reduce risks to its survival. In general, it is thought that zokors avoid light and wind, which is consistent with their behavior of sealing burrow entrances. However, direct evidence from field experimental research has been lacking. This study set up 68 field sampling points in a meadow steppe in Inner Mongolia from August to September, 2014 and used a wind-light isolator to study the effects of wind and light factors on zokor burrow entrance sealing behavior. The results showed that there were no significant correlations between wind or light factors and the frequency of zokor burrow entrance sealing. Therefore, wind and light factors are not direct factors associated with zokors actively sealing burrow entrances.
东北鼢鼠是一种主要分布于中国北方内蒙古草原草甸的啮齿动物。由于在地下环境中经历了漫长的进化历史,鼢鼠具有一种适应性行为:封堵洞穴入口。当洞穴受损,出现暴露的洞口时,在相对较短的时间内,鼢鼠就会积极地封堵洞口以降低生存风险。一般认为,鼢鼠避光避风,这与它们封堵洞穴入口的行为相符。然而,一直缺乏来自野外实验研究的直接证据。本研究于2014年8月至9月在内蒙古的一个草原草甸设置了68个野外采样点,并使用了一个风-光隔离器来研究风和光因素对鼢鼠洞穴入口封堵行为的影响。结果表明,风和光因素与鼢鼠洞穴入口封堵频率之间没有显著相关性。因此,风和光因素不是与鼢鼠主动封堵洞穴入口相关的直接因素。
