猫的气味对黑线姬鼠行为的影响

以农田主要害鼠黑线姬鼠为研究对象,研究猫的尿液气味和猫的毛皮气味对其行为的影响,并探讨两种气味源的有效性.结果:两种气味源都能影响黑线姬鼠的行为,其修饰行为、取食行为、攻击行为的频次都不同程度的减少,而隐藏行为的时间和探究行为的频次变化不显著.不同的气味源对黑线姬鼠行为影响的有效性不同,猫的毛皮气味对黑线姬鼠行为的影响比尿液气味的影响显著.表明黑线姬鼠能够通过气味识别捕食风险的存在以及强度,并采用相应的策略.

Influence of Cat Odors on the Behavior of Striped Field Mouse

Striped field mouse(Apodemus agrarius) is one of the main pest rodent of the cropland.This study was aimed at determing the influence of cat odors which derived from cat's urine and fur on the behavior of the striped field mouse.We also investigated the efficacy of the two odor sources,and found that the two odor sources both can influence the behaviors of the mouse.The self-grooming,feeding and attacking behaviors all decreased at different levels,but the influence of concealed behavior and exploration were not obvious.Different odor sources had different efficacy.Fur-derived predator odors may have a more profound lasting influence on striped field mouse than those derived from urine.These results indicate that cat odors could influence the behaviors of the striped field mouse and the mouse had ability to assess the predation risk and adjust their behaviors according to the degree of the risk.
