将雌性成体和雌雄亚成体大仓鼠 (Cricetulustriton)长期 (4周 )暴露给过量的黄鼬 (Mustelasibirica)肛腺分泌物 ,观察其行为和生理状态的变化 ,并通过与我们以前有关黄鼬气味对成年雄鼠影响的研究结果进行比较 ,表明黄鼬气味对不同性别和不同年龄大仓鼠的胁迫效应和生殖抑制存在差异。发现黄鼬气味对雌性大仓鼠的影响较雄性小 ,对亚成体的影响较成体小 ,这与雌性和未成年动物对各种胁迫因素的反应更敏感的普遍现象相反。在成年鼠中 ,雌雄鼠的攻击行为都受到黄鼬气味的抑制 ;但天敌气味使雌性的胁腺膨大 ,对胁腺标记和肾上腺大小无影响 ;成年雄鼠的肾上腺膨大 ,胁腺萎缩 ,标记减少。在亚成体中 ,除了雄性胁腺受到抑制(与成年雄鼠相同 )外 ,雌雄鼠的肾上腺和雌性的胁腺未受影响。亚成体实验鼠的体重都比对照组低 ,但成年鼠的体重未受影响。另外 ,与以往对其它鼠类的研究结果一致 ,天敌气味并不影响成年鼠的生殖器官 ,却抑制了未成年雄鼠的附睾和未成年雌鼠的子宫。这些差异可能和生理基础的性二态以及可能面临的被捕食风险大小有关
Female adult and adult male and female Cricetulustriton were exposed to an excessive amount of Mustelasibirica anal gland secretion for a long period of time (4 weeks) to observe their behavioral and physiological changes. The results of the comparison of the effects of the rats showed that there was a difference in the effects of the yellow ferret smell on the stress effects and reproductive suppression of hamsters of different sexes and ages. It was found that the effect of the yellow ferret smell on female hamsters was smaller than that on males, and their effects on adults were smaller than those on adults. This is contrary to the common phenomenon that females and juveniles are more sensitive to various stressors. In adult mice, the attack behavior of both male and female rats was inhibited by the smell of the yellow ferret; however, the predatory odor of the natural enemies enlarged the glandular glands of the females, which had no effect on the gonadal and adrenal size. The adrenal glands of adult males became swollen, . In adulthood, the male and female glands of the adrenal and female glands were unaffected, except that the male gonads were inhibited (same as adult males). The body weight of the sub-adult mice was lower than that of the control group, but the body weight of the adult mice was unaffected. In addition, consistent with previous studies on other rodents, odors of natural enemies did not affect the reproductive organs of adult mice, but suppressed the uterus of the epididymis and minors of the underage males. These differences may be related to the physiological basis of sexual dimorphism and may be the size of the predation risk
