正如一些长期和时间密集的研究所示，密切相关的同域物种可以对彼此施加强选择，导致表型进化的戏剧性例子。在这里，我们使用的发生数据，以确定集群的同域Sceloporus蜥蜴物种和测试是否Sceloporus物种往往与其他物种，不同的身体大小共存，因为我们会期望当有同域同源物之间的竞争。我们发现Sceloporus物种可以分为16个独特的生物区。位于高纬度的生物区往往更大，物种更少，遵循Rapoport规则和纬度多样性梯度。物种丰富度与各生物区的生物群落数量和海拔异质性呈正相关。此外，大多数生物区显示出系统发育分散不足的迹象，这意味着密切相关的物种往往出现在地理位置接近的地方。最后，我们发现，尽管身体大小相似的Sceloporus物种倾向于在地理上聚集，但体型较小的Sceloporus物种更经常与体型较大的Sceloporus物种共生，而体型较大的物种在地理上和遗传上相互聚集。这些结果表明，在现存Sceloporus物种的群落组成是异地进化的结果，密切相关的物种进入不同的生物群落，种间相互作用，不同的身体大小的物种之间的同域性。我们的生物信息学方法提供了独特而详细的见解，了解由生态和形态上不同的物种组成的分支如何分布在大的地理空间和进化时间。在这里，我们使用开源数据库来了解同域物种对表型的进化影响。我们发现，物种在美洲的分布并不均匀，小型蜥蜴物种在地理上过于分散，并且经常与不同大小的物种共存。相反，大型物种在地理空间上集群，并且经常与其他大型物种同域
As shown from several long‐term and time‐intensive studies, closely related, sympatric species can impose strong selection on one another, leading to dramatic examples of phenotypic evolution. Here, we use occurrence data to identify clusters of sympatric Sceloporus lizard species and to test whether Sceloporus species tend to coexist with other species that differ in body size, as we would expect when there is competition between sympatric congeners. We found that Sceloporus species can be grouped into 16 unique bioregions. Bioregions that are located at higher latitudes tend to be larger and have fewer species, following Rapoport's rule and the latitudinal diversity gradient. Species richness was positively correlated with the number of biomes and elevation heterogeneity of each bioregion. Additionally, most bioregions show signs of phylogenetic underdispersion, meaning closely related species tend to occur in close geographic proximity. Finally, we found that although Sceloporus species that are similar in body size tend to cluster geographically, small‐bodied Sceloporus species are more often in sympatry with larger‐bodied Sceloporus species than expected by chance alone, whereas large‐bodied species cluster with each other geographically and phylogenetically. These results suggest that community composition in extant Sceloporus species is the result of allopatric evolution, as closely related species move into different biomes, and interspecies interactions, with sympatry between species of different body sizes. Our phyloinformatic approach offers unique and detailed insights into how a clade composed of ecologically and morphologically disparate species are distributed over large geographic space and evolutionary time. Here, we use open source databases to understand the evolutionary impact of sympatric species on phenotypes. We found that species are not evenly distributed across the Americas and that small‐bodied lizard species are geographically overdispersed and are often found in sympatry with species of a different size class. Conversely, large‐bodied species cluster in geographic space and are often in sympatry with other large species
