摘要现场内分泌学技术允许收集样品（即，这些数据揭示了个体应对环境挑战、繁殖、迁移和调节其生命周期各个方面的机制。野外内分泌学技术也可用于解决保护生物学中的许多问题。我们简要回顾了过去和现在的方式，内分泌方法用于监测受威胁的物种，确定潜在的压力和记录对环境干扰的反应。然后，我们专注于保护的一个重要方面：自由生活的人口如何应对人类干扰，特别是在生态旅游。繁殖中的成年麦哲伦企鹅，Spheniscus magellanicus，似乎对游客适应得很好，并在一个季节约有7万人参观的地区繁殖。在未被感染的鸟类暴露于人类后，皮质酮的基线水平恢复正常。然而，企鹅幼鸟似乎表现出更高的肾上腺皮质反应，以处理在巢暴露于游客的压力，相比，小鸡生活在与人类入侵隔离的地区。考虑到发育过程中暴露于压力会对成年人科普压力的方式产生深远的影响，游客对小鸡的这种潜在影响可能会产生长期后果。这一领域的内分泌方法确定了一个压力源，没有观察到通过监测行为单独。
Abstract Field endocrinology techniques allow the collection of samples (i.e., blood, urine, feces, tissues) from free-living animals for analysis of hormones, receptors, enzymes, etc. These data reveal mechanisms by which individuals respond to environmental challenges, breed, migrate and regulate all aspects of their life cycles. Field endocrinology techniques can also be used to address many issues in conservation biology. We briefly review past and current ways in which endocrine methods are used to monitor threatened species, identify potential stressors and record responses to environmental disturbance. We then focus on one important aspect of conservation: how free-living populations respond to human disturbance, particularly in relation to ecotourism. Breeding adult Magellanic penguins, Spheniscus magellanicus, appear to habituate well to tourists, and breed in an area where about 70,000 people visit during the season. Baseline levels of corticosterone return to normal after exposure of naïve birds to humans. However, penguin chicks appear to show a heightened adrenocortical response to handling stress in nests exposed to tourists, compared to chicks living in areas isolated from human intrusions. Given that developmental exposure to stress can have profound influences on how individuals cope with stress as adults, this potential effect of tourists on chicks could have long-term consequences. This field endocrine approach identified a stressor not observed through monitoring behavior alone.
