在室外围栏中，研究了水田鼠对捕食者气味的反应。研究人员让水田鼠进入两个食物笼子，一个笼子里有捕食者的气味，另一个笼子里没有气味，并对它们进行了22小时的录像。羊的气味也被用作新气味的对照。捕食者是美洲水貂和褐鼠。田鼠对羊的气味和没有气味的反应没有区别。田鼠进入含有水貂气味的处理笼的次数明显少于进入对照笼的次数，这表明它们避开了前者。它们从笼子里收集的食物也更少，在笼子里呆的时间也更短。田鼠对水貂的气味比老鼠的气味更避之不及。事实上，实验动物之前没有接触过美国水貂，这表明这种反应是天生的。这些结果还表明，水鼠认为水貂比大鼠更危险，尽管它们会避开这两种物种的气味。版权所有1999动物行为研究协会。
We investigated the response of water voles to the odours of predators in outdoor enclosures. Water voles were given access to two food cages, one containing the odour of a predator and the other containing no odour, and were videotaped for 22 h. Sheep odour was also used as a control for novel odour. The predators were American mink, Mustela vison, and brown rat, Rattus norvegicus. There was no difference in the voles' response to sheep odour and no odour. The voles entered the treatment cages containing the mink's odour significantly fewer times than they entered the control cages, indicating avoidance of the former. They also gathered less food from, and stayed a shorter time inside, the treatment cages. The voles avoided the mink's odour more than the rat's odour. The fact that the experimental animals had not had previous contact with American mink suggests that the response is innate. These results also suggest that water voles perceived mink as a greater risk than rats, although they avoided odours of both these species.
