Abstract：
On a global scale, biodiversity is geographically structured into regions of biotic similarity. Delineating these regions has been mostly targeted for tetrapods and plants, but those for hyperdiverse groups such as insects are relatively unknown. Insects may have higher biogeographic congruence with plants than tetrapods due to their tight ecological and evolutionary links with the former, but it remains untested. Here, we develop a global regionalization for a major and widespread insect group, ants, based on the most comprehensive distributional and phylogenetic information to date, and examine its similarity to regionalizations for tetrapods and vascular plants. Our ant regionalization supports the newly proposed Madagascan and Sino-Japanese realms based on tetrapod delineations, and it recovers clusters observed in plants but not in tetrapods, such as the Holarctic and Indo-Pacific realms. Quantitative comparison suggests strong associations among different groups-plants showed a higher congruence with ants than with tetrapods. These results underscore the wide congruence of diverse distribution patterns across the tree of life and the similarities shared by insects and plants that are not captured by tetrapod groups. Our analysis highlights the importance of developing global biogeographic maps for insect groups to obtain a more comprehensive geographic picture of life on Earth.
摘要：
在全球范围内,生物多样性在地理上被构造成生物相似性区域。划定这些区域主要针对四足动物和植物，但是那些像昆虫这样的超多样化群体是相对未知的。昆虫与植物的生物地理一致性可能高于四足动物，因为它们与四足动物有着紧密的生态和进化联系，但它仍未测试。这里,我们为一个主要和广泛的昆虫群体制定了全球区域化，蚂蚁,根据迄今为止最全面的分布和系统发育信息，并检查其与四足动物和维管植物的区域化的相似性。我们的蚂蚁区域化支持新提出的马达加斯加和基于四足动物划定的中日领域，它恢复了在植物中观察到的簇，但在四足动物中没有，如北极和印度-太平洋领域。定量比较表明，不同组之间的强烈关联-植物与蚂蚁的一致性高于四足动物。这些结果强调了生命树中各种分布模式的广泛一致性，以及四足类动物无法捕获的昆虫和植物的相似性。我们的分析强调了为昆虫群体开发全球生物地理地图以获得更全面的地球生命地理图景的重要性。
