摘要

在蜥蜴中，飞行起始距离(FID)，即猎物和捕食者开始逃跑时的距离，会受到许多内在和外在因素的影响，包括性别、温度和明显程度。在这里，我们报告了一项对来自墨西哥奇瓦瓦州塞拉德萨马柳卡的华丽树蜥蜴(Urosaurus ornatus)种群的FID的研究，这些蜥蜴由于其背部颜色与背景混合而变得隐秘。在我们的研究种群中，华丽尾龙允许近距离接近(平均FID = 65 cm)。平均FID在男性和女性之间没有差异。我们还发现，人体、空气或衬底温度对FID没有影响。我们观察到的短FID可能与花楸的隐性有关。

Flight initiation distance of Urosaurus ornatus from the Sierra de Samalayuca, Mexico

In lizards, flight initiation distance (FID), the distance between a prey individual and a predator when escape begins, can be affected by numerous intrinsic and extrinsic factors, including sex, temperature, and level of conspicuousness. Here we report on a study of FID in a population of Ornate Tree Lizards, Urosaurus ornatus, from the Sierra de Samalyuca, Chihuahua, Mexico which are cryptic due to their dorsal coloration blending into their background. Urosaurus ornatus in our study population allowed close approaches (mean FID = 65 cm). Mean FID did not differ between males and females. We also found no effect of body, air, or substrate temperature on FID. The short FID we observed may be related to the cryptic nature of U. ornatus.

期刊介绍： Acta Herpetologica, a journal open to academics all over the world, offers itself as a new site for the presentation and discussion of the most recent results in the field of research on Amphibians and Reptiles, both living and extinct. The official journal of the Societas Herpetologica Italica (S.H.I.), Acta Herpetologica publishes original works – extended articles, short notes and book reviews – mostly in English, dealing with the biology and diversity of Amphibians and Reptiles.
