蜥蜴以其特殊的生态形态而闻名，其特征是与特定微生境的使用有关的一系列特征的趋同进化。许多相同的性状在新的选择压力下迅速进化，并得到了很好的研究。相比之下，尾冠，一个特征，目前在一个子集的血统，已几乎完全被忽视。在物种内和物种之间的尾嵴形态的变化仍然在很大程度上未被研究，因为没有功能的特点。在这里，我们使用城市化提供的自然实验，以询问是否尾冠大小不同的城市和森林种群之间的冠变色龙（Anolis cristatellus）在加勒比海岛屿的波多黎各。我们发现，尾冠大小主要不同地区之间，然而，在区域内，波峰总是在城市比森林环境中更大。这种大小上的差异与炎热，干燥的条件和稀疏分布的栖息地，典型的城市网站，导致有趣的可能性，尾冠可能是下差异的自然选择信号和/或因为城市栖息地的温度调节的挑战。需要进一步的研究来阐明这种未充分研究的特征的功能意义和进化。
Anolislizards are well known for their specialist ecomorphs characterized by the convergent evolution of suites of traits linked to the use of particular microhabitats. Many of these same traits evolve rapidly in response to novel selection pressures and have been very well studied. In contrast, the tail crest, a feature present in a subset of lineages, has been almost entirely overlooked. Variation in tail crest morphology within and among species remains largely unstudied, as does the function of the trait. Here, we use the natural experiment provided by urbanization to ask whether tail crest size differs between urban and forest populations of the crested anole (Anolis cristatellus) across the Caribbean island of Puerto Rico. We find that tail crest size differs primarily between regions; however, within regions, crests are invariably larger in urban than in forest environments. This difference in size is correlated with the hotter, drier conditions and sparser distribution of perches that typify urban sites, leading to the intriguing possibility that the tail crest might be under differential natural selection for signalling and/or because of the thermoregulatory challenge of urban habitats. Further study is required to shed light on the functional significance and evolution of this under-studied trait.
