研究背景高山山脉的兴起被广泛认为是陆地植物迅速多样化和生物多样性热点形成的因素之一。据报告，安第斯山脉迅速上升的影响有支持性证据，但迄今为止，对“世界屋脊”影响的这一假设探讨较少。喜马拉雅山的形成，特别是近2000万年来青藏高原的上升，改变了主导东南亚当前气候的季风制度。在这里，我们推断的假设，喜马拉雅山的崛起产生了强烈的影响，植物多样性的生物多样性热点的中国西南Mountains.ResultsOur的衍生蕨类植物属Lepisorus恢复的多样化模式的分析证据与加强东南亚季风植物多样性的变化。中国西南部或中国西南部和日本被恢复为假定的地区的起源ofLepisorus和增强季风制度被发现塑造的早期多样化的属，以及随后的辐射在晚中新世和上新世.ConclusionsWe报告的植物多样化和气候变化的巧合喜马拉雅山的隆起所造成的新证据。这些结果进行了讨论的背景下，不完整的分类群抽样的影响，分歧时间估计的不确定性，以及目前的方法来评估多样化率的局限性。
BackgroundThe rise of high mountain chains is widely seen as one of the factors driving rapid diversification of land plants and the formation of biodiversity hotspots. Supporting evidence was reported for the impact of the rapid rise of the Andean mountains but this hypothesis has so far been less explored for the impact of the “roof of the world”. The formation of the Himalaya, and especially the rise of the Qinghai–Tibetan Plateau in the recent 20 million years, altered the monsoon regimes that dominate the current climates of South East Asia. Here, we infer the hypothesis that the rise of Himalaya had a strong impact on the plant diversity in the biodiversity hotspot of the Southwest Chinese Mountains.ResultsOur analyses of the diversification pattern of the derived fern genusLepisorusrecovered evidence for changes in plant diversity that correlated with the strengthening of South East Asian monsoon. Southwest China or Southwest China and Japan was recovered as the putative area of origin ofLepisorusand enhancing monsoon regime were found to shape the early diversification of the genus as well as subsequent radiations during the late Miocene and Pliocene.ConclusionsWe report new evidence for a coincidence of plant diversification and changes of the climate caused by the uplift of the Himalaya. These results are discussed in the context of the impact of incomplete taxon sampling, uncertainty of divergence time estimates, and limitations of current methods used to assess diversification rates.
