捕食者的气味是非侵入性的自然应激源，具有高度的行为学相关性。研究了布氏田鼠（Lasiopodomys brandtii）暴露于家猫（Felis catus）、鼬鼠（Mustela sibirica）、蛇（Xenopeltis hainanensis）、山羊（Capra aegagrus）和蒸馏水（对照）粪便后的行为和激素反应以及下丘脑内侧c-fos mRNA的表达变化。100只田鼠在防御性撤退装置中进行了测试。与暴露于山羊气味和对照气味的田鼠相比，暴露于捕食者气味的田鼠血清促肾上腺皮质激素和皮质酮水平显著升高。高水平的c-fos mRNA表明捕食者气味诱导的下丘脑内侧强烈激活。我们的研究结果显示，勃兰特田鼠对捕食者的气味有明显的恐惧反应，并且它们可以熟练地区分来自不同物种的气味，其中来自同域捕食者的气味引发的反应最高。
Predator odors are nonintrusive natural stressors of high ethological relevance. Behavioral and hormonal responses and changes in the expression of medial hypothalamic c-fos mRNA were examined in Brandt's voles (Lasiopodomys brandtii) after exposure to feces of a domestic cat (Felis catus), weasel (Mustela sibirica), snake (Xenopeltis hainanensis), goat (Capra aegagrus), and distilled water (control). One hundred voles were tested in the defensive withdrawal apparatus. Adrenocorticotropic hormone and corticosterone serum levels significantly increased when voles were exposed to the predator odors compared to voles exposed to goat and control odors. A significant high c-fos mRNA level indicates a strong predator odor-induced activation of the medial hypothalamus of the tested voles. Our results display significant fear responses of Brandt's voles exposed to predator odors and that they can skillfully differentiate between odors from different species with odors from sympatric predators triggering the highest responses.
