Abstract

Abstract. In the Monte region of Argentina, the local population is causing severe habitat degradation by extracting native vegetation and domestic animal grazing. To assess whether disturbed environments have higher levels of asymmetry than control environments, we examined morphological variation and fluctuating asymmetry in the cephalic region of the longtail whiptail lizard Aurivela longicauda (Teiidae) using a Procrustes analysis with geometric morphometry. This is the first study of asymmetry using geometric morphometry in a lizard from Argentina. While there was no difference in the size of the cephalic region between the two environments, there were differences in shape between the right and left side of the lizard's head (object symmetry), the differences being greater at disturbed sites (fluctuating asymmetry), suggesting that anthropogenic activities may act as stressors driving alterations in the fitness (reproduction) of reptile populations. Fluctuating asymmetry analysis is an excellent conservation biology and environmental monitoring tool for measuring stress in different organisms.

不同人为干扰水平下爬行动物的波动不对称与环境应激

摘要在阿根廷的蒙特地区，当地人口因采伐本地植被和放牧家畜而造成严重的生境退化。为了评估受干扰环境是否比控制环境具有更高水平的不对称性，我们使用Procrustes几何形态分析方法研究了长尾鞭尾蜥(Teiidae)头侧区域的形态变化和波动不对称性。这是首次利用几何形态测量学对阿根廷蜥蜴的不对称性进行研究。虽然两种环境中头部区域的大小没有差异，但蜥蜴头部左右两侧的形状存在差异(物体对称)，在受干扰的部位差异更大(波动不对称)，这表明人类活动可能是驱动爬行动物种群适应性(繁殖)改变的压力源。波动不对称分析是一种很好的保护生物学和环境监测工具，用于测量不同生物体内的应力。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
