循环糖皮质激素（GC）是野生动物中最常用的应激生物标志物。然而，它们作为查明和/或管理危险物种的工具的效用各不相同。在这里，我们采取了一个非常广泛的保护生理学的方法，询问是否国际自然保护联盟（IUCN）的上市状态（关注与没有明显的关注）和/或地理范围内的位置（边缘与非边缘）预测的基线和约束后的皮质酮（CORT）浓度在许多鸟类和爬行动物物种。即使这样的方法可以被视为粗糙，我们在分析中问CORT浓度是否可能是有用的牵连物种的风险。事实上，我们的努力，依靠激素库，野生动物类固醇的数据库，补充了其他几个大规模的努力，在这个问题上，以描述和理解GC的变化。使用遗传学的贝叶斯方法，我们发现几乎没有证据表明，无论是世界自然保护联盟的地位或边缘/非边缘位置的地理分布与GC水平。然而，我们确实证实了以前研究中描述的模式，即物种之间的繁殖条件和进化相关性预测了一些GC变异。鉴于我们的工作范围广泛，我们不愿意得出结论，IUCN的地位和位置在一定范围内是无关的GC法规。我们鼓励未来对高危人群的GC进行更有针对性的研究，以揭示导致IUCN列名的因素或范围边缘的环境条件如何影响个体表现和健康，特别是我们无法在这里研究的哺乳动物、两栖动物和鱼类，因为数据目前不可用。
Circulating glucocorticoids (GCs) are the most commonly used biomarkers of stress in wildlife. However, their utility as a tool for identifying and/or managing at-risk species has varied. Here, we took a very broad approach to conservation physiology, asking whether International Union for the Conservation of Nature (IUCN) listing status (concern versus no obvious concern) and/or location within a geographic range (edge versus non-edge) predicted baseline and post-restraint concentrations of corticosterone (CORT) among many species of birds and reptiles. Even though such an approach can be viewed as coarse, we asked in this analysis whether CORT concentrations might be useful to implicate species at risk. Indeed, our effort, relying on HormoneBase, a repository of data on wildlife steroids, complements several other large-scale efforts in this issue to describe and understand GC variation. Using a phylogenetically informed Bayesian approach, we found little evidence that either IUCN status or edge/non-edge location in a geographic distribution were related to GC levels. However, we did confirm patterns described in previous studies, namely that breeding condition and evolutionary relatedness among species predicted some GC variation. Given the broad scope of our work, we are reluctant to conclude that IUCN status and location within a range are unrelated to GC regulation. We encourage future more targeted efforts on GCs in at-risk populations to reveal how factors leading to IUCN listing or the environmental conditions at range edges impact individual performance and fitness, particularly in the mammals, amphibians, and fish species we could not study here because data are currently unavailable.
