摘要

Recent advances in phylogenomics allow for the use of large amounts of genetic information in phylogenetic inference. Ideally, the increased resolution and accuracy of such inferences facilitate improved understanding of macroevolutionary processes. Here, we integrate ultraconserved elements (UCEs) with fossil and biogeographic range data to explore diversification and geographic range evolution in the diverse turtle ant genus Cephalotes Latreille, 1802 (Hymenoptera: Formicidae). We focus on the potential role of the uplift of the Panamanian land bridge and the putative ephemeral GAARlandia land bridge linking South America and the Antilles in shaping evolution in this group. Our phylogenetic analyses provide new resolution to the backbone of the turtle ant phylogeny. We further found that most geographic range shifts between South America and Central America regions were temporally consistent with the development of the Panamanian land bridge, while we did not find support for the GAARlandia land bridge. Additionally, we did not infer any shifts in diversification rates associated with our focal land bridges, or any other historical events (we inferred a single diversification rate regime across the genus). Our findings highlight the impact of the Panamanian land bridge for Cephalotes geographic range evolution as well as the influence of taxonomic sampling on macroevolutionary inferences.

系统生理学学的最新进展允许在系统发育推断中使用大量遗传信息。理想情况下，这种推论的分辨率和准确性的提高有助于提高对宏观进化过程的理解。在这里，我们将超级保守的元素（UCE）与化石和生物地理范围数据整合在一起，以探索多样化的乌龟蚂蚁属Cephalotes latreille，1802年（膜翅目：福兰科）的多样化和地理范围演变。我们专注于巴拿马陆上桥的提升和推定的短暂的Gaarlandia Land Bridge，将南美和安提尔斯连接起来在塑造这一群体中的进化中。我们的系统发育分析为乌龟蚂蚁系统发育的主干提供了新的分辨率。我们进一步发现，南美洲和中美洲地区之间的大多数地理范围都与巴拿马陆桥的发展一致，而我们没有找到对Gaarlandia Land Bridge的支持。此外，我们没有推断与我们的焦点桥或任何其他历史事件相关的多元化率的任何变化（我们推断了整个属的单个多元化率制度）。我们的发现突出了巴拿马土地桥对头座地理范围演变的影响，以及分类抽样对宏观进化推论的影响。
