Climatic variation has long been regarded as a primary source of morphological variation. However, there is mixed support for the adherence of reptiles to ecogeographical hypotheses, such as Bergmann’s rule (body size decreases with temperature) and Allen’s rule (limb length increases with temperature). We quantified body and limb morphology among the diverse Australian gecko fauna (4 families, 30 genera, 226 of the 231 described species) to investigate environmental correlates of morphological variation in this radiation.

澳大利亚壁虎的形态多样性与环境的关系

气候变化长期以来一直被视为形态变化的主要来源。但是，对于爬行动物遵守生态地理假设（例如伯格曼法则（体型随温度而减小）和艾伦法则（肢体随温度而增加））的支持程度参差不齐。我们量化了澳大利亚壁虎不同动物（4个科，30个属，231个被描述物种中的226个）的身体和肢体形态，以研究这种辐射的形态变化与环境的相关性。
