Abstract

Morphology is among the most important traits influencing the interaction of individual animals with their environments. Fossoriality reflects this functional association between morphology and the use of subterranean habitats and their associated environmental characteristics. Lizards in the families Gymnophthalmidae and Alopoglossidae are model organisms to examine the interplay between morphology and fossoriality because great morphological diversity exists among species, including varying degrees of body elongation and limb reduction, and they have a wide geographical distribution in the Neotropical region. We analysed the morphology of 101 microteiid species and created an index to evaluate their degree of fossoriality. From this index, we traced the evolution of fossoriality in these lizards and assessed its primary environmental correlates. We found that fossoriality evolved independently in several lineages, mainly associated with high temperature and low precipitation, characteristic of more arid and sandy environments.
微体蜥蜴的化石进化
形态是影响动物个体与其环境相互作用的最重要特征之一。化石性反映了形态与利用地下栖息地及其相关环境特征之间的功能性联系。蜥蜴科(Gymnophthalmidae)和蜥蜥科(Alopoglossidae)是研究形态和穴居性之间相互作用的模式生物,因为不同物种之间存在着巨大的形态多样性,包括不同程度的身体伸长和肢体缩小,而且它们在新热带地区有着广泛的地理分布。我们分析了 101 个微畸形物种的形态,并创建了一个指数来评估它们的化石化程度。根据这一指数,我们追溯了这些蜥蜴化石性的演化过程,并评估了其主要的环境相关因素。我们发现,化石性在几个种系中独立进化,主要与高温和低降水量有关,这是较干旱和多沙环境的特征。

期刊介绍: The Zoological Journal of the Linnean Society publishes papers on systematic and evolutionary zoology and comparative, functional and other studies where relevant to these areas. Studies of extinct as well as living animals are included. Reviews are also published; these may be invited by the Editorial Board, but uninvited reviews may also be considered. The Zoological Journal also has a wide circulation amongst zoologists and although narrowly specialized papers are not excluded, potential authors should bear that readership in mind.
