鸟类应激检测方法探讨

Discussion on Measuring Methods of Stress in Birds

糖皮质激素(GC)可以用来反映鸟类的应激水平、监测鸟类的应激状况,进而了解环境对鸟类生存和繁殖的影响。以往的研究中,血液、粪便以及羽毛均可作为鸟类糖皮质激素检测的材料,但目前在我国主要采用血液和粪便,对羽毛糖皮质激素的检测及其生态学研究尚属于空白,需要对激素的检测方法进一步完善。本文介绍了血液、粪便和羽毛这3种采样技术的研究进展,包括每种采样技术的优缺点、影响检测的因素,论述了羽毛作为一项非损伤或微损伤采样技术在鸟类应激监测中的重要性,并建议在激素研究中,羽毛的采样技术可以作为血液和粪便采样的补充手段,而不是替代手段。在此基础上,本文还就羽毛糖皮质激素检测的应用展开了探讨,其形成机制及其生态学意义是未来研究的重点。

Glucocorticoid could be used to reflect the stress level of birds and to understand the environmental influence on bird survival and reproduction.In previous studies,blood,feces and feather were used as glucocorticoid test materials of birds.But so far only blood and feces were used in Chinese references.The feather glucocorticoids detection and its ecological research are still almost in blank,and the hormone detection method need to be further studied.In this article,we reviewed the research progress of blood,feces and feather sampling techniques,including the advantages and disadvantages of each sampling technique and factors affecting the detection rates.And then we discussed the importance of the feather sampling as a noninvasive or micro damage sampling technique in stress monitoring of birds.We suggest that feather sampling technology complement the sampling of blood and feces rather than the alternative hormone studies.Based on this study,the application of feather corticosteroid testing is discussed.Its formation mechanism and ecological significance could be the focus of future research.
