Explosive Cenozoic origin and diversity-dependent diversification dynamics shaped the evolution of Australian skipper butterflies

Australia was predominantly tropical for most of the early Cenozoic, then transitioned to a cooler and drier climate in the Oligocene. In response to this increasing aridity, some lineages adapted to more xeric ecosystems, contracted, or became restricted to increasingly fragmented mesic refugia, or went extinct. Yet, the lack of macroevolutionary studies at a continental scale precludes a better understanding of Australian biodiversity patterns and processes during the Cenozoic. Here, we infer a robust dated phylogenomic tree for a radiation of Australian endemic butterflies, the Trapezitinae skippers, to test the impact of biotic and abiotic drivers on Cenozoic diversification dynamics in Australia. These butterflies originated during the Eocene (ca. 42 Ma) in the mesic biome of Australia. Trapezitinae exploded in diversity during a cool, dry period in the late Oligocene and early Miocene, then experienced a sharp deceleration in speciation. Xeric ecosystems appear to have been coloni..., , ----------------------------------------------------------------------------------------------------------README File for Dryad repository on \"Explosive Cenozoic origin and diversity-dependent diversification dynamics shaped the evolution of Australian skipper butterflies\"----------------------------------------------------------------------------------------------------------Number of files: 10----------------------------------------------------------------------------------------------------------Description:Paper appendices / supplementary informationFile S1 - IQ-TREE Best Scoring ML tree.treFile S2 - wASTRAL MSC tree.treFile S3 - BEAST MCC 14ULRC BDeath.treTable S1 - Taxon Sampling.xlsxTable S2 - Genomic Matrix Composition.xlsxTable S3 - Biogeography Data.xlsxTable S4 - BEAST Results.xlsxTable S5 - TreePar Results.xlsxTable S6 - RPANDA Results.xlsxTable S7 - HiSSE Results.xlsxSee the paper for more descriptions of these files----------------------------------------------------------...

澳大利亚在新生代早期的绝大多数时期以热带气候为主，随后在渐新世时期转变为更为凉爽干燥的气候。为应对日益加剧的干旱化进程，部分演化支适应了更为干旱的生态系统，其分布范围发生收缩，或被局限在日益碎片化的湿润避难所中，甚至走向灭绝。然而，缺乏大陆尺度的宏观演化研究，阻碍了我们对新生代澳大利亚生物多样性模式与演化过程的深入理解。本研究针对澳大利亚特有蝴蝶类群——弄蝶亚科（Trapezitinae）的辐射演化，构建了稳健的定年系统发育基因组树，以检验生物与非生物驱动因子对澳大利亚新生代多样化动态的影响。该类蝴蝶起源于始新世（约4200万年前）的澳大利亚湿润生物群落。在渐新世晚期与中新世早期的凉爽干燥时期，弄蝶亚科的多样性经历爆发式增长，随后物种形成速率出现急剧放缓。干旱生态系统似乎已被定殖……
