摘要
【ABSTRACT】Captive management of endangered species is a common conservation strategy. Monitoring the endocrine response related to reproduction and the increase of fecal cortisol metabolites is key to evaluating reproductive well‐being and condition. We noninvasively assessed the endocrine status of captive European minks (Mustela lutreola) housed at Foundation for Research in Ethology and Biodiversity [FIEB] (a Spanish biodiversity conservation center) by measuring fecal glucocorticoid cortisol metabolite levels and testosterone, and progesterone metabolite levels. Males showed higher fecal cortisol and testosterone metabolite levels while no differences in fecal progesterone metabolite levels were found between sexes. Fecal levels of the three hormones were positively correlated. Individuals born in FIEB had lower fecal cortisol metabolites than those born in other centers and their values did not increase due to captivity duration. Hormone values obtained in FIEB could serve as a reference for this species management. However, further studies are required to ensure the well‐being and reproductive success of captive and wild populations.

【摘要】濒危物种的圈养管理是一种常见的保护策略。监测与繁殖有关的内分泌反应和粪便皮质醇代谢产物的增加是评估生殖良好福祉和状况的关键。我们非侵入性地评估了在伦理学和生物多样性研究基金会[fieb]（西班牙生物多样性保护中心）的圈养欧洲貂（Mustela lutreola）的内分泌状态，通过测量粪便糖皮质激素皮质蛋白蛋白蛋白蛋白蛋白蛋白蛋白酶醇代谢物和睾丸激素和睾丸激素和叶骨酮代理水平。雄性显示出较高的粪便皮质醇和睾丸激素代谢物水平，而性别之间的粪便孕酮代谢物水平没有差异。三种激素的粪便水平呈正相关。在FIEB中出生的人的粪便皮质醇代谢物比其他中心出生的人较低，由于被圈养的持续时间，其价值没有增加。在FIEB中获得的激素值可以作为该物种管理的参考。但是，需要进一步的研究以确保圈养和野生人群的福祉和生殖成功。
