禾本科是物种最丰富，生态和经济上最重要的植物目之一，通常是开放的栖息地，由独特的特征组合而成。我们测试了六个假设，在开放和封闭的栖息地在世界各地的Poales的进化和组装，并检查多样化模式是否表现出平行evolution.We抽样42%的Poales物种，并从世界清单的维管植物数据库，这是开放/封闭的栖息地的分类学专家得分的数据相结合，获得了分类和植物地理数据。构造了Poales的一棵过时超树。我们整合了空间遗传学与区域化分析，历史地理学和祖先状态estimations.Diversification Poales和组装的开放和封闭的栖息地的动态进化过程中，不同的血统，时间和空间，最突出的是在热带和南部纬度。我们的研究结果揭示了物种丰富的禾本科和莎草科的栖息地和性状转变的平行和经常性模式。小科表现出独特的，往往是不同的进化轨迹。禾本科已经取得了全球优势，通过平行进化在开放的栖息地，显着的，空间和遗传限制的分歧，严格封闭的栖息地。
Poales are one of the most species‐rich, ecologically and economically important orders of plants and often characterise open habitats, enabled by unique suites of traits. We test six hypotheses regarding the evolution and assembly of Poales in open and closed habitats throughout the world, and examine whether diversification patterns demonstrate parallel evolution.We sampled 42% of Poales species and obtained taxonomic and biogeographic data from the World Checklist of Vascular Plants database, which was combined with open/closed habitat data scored by taxonomic experts. A dated supertree of Poales was constructed. We integrated spatial phylogenetics with regionalisation analyses, historical biogeography and ancestral state estimations.Diversification in Poales and assembly of open and closed habitats result from dynamic evolutionary processes that vary across lineages, time and space, most prominently in tropical and southern latitudes. Our results reveal parallel and recurrent patterns of habitat and trait transitions in the species‐rich families Poaceae and Cyperaceae. Smaller families display unique and often divergent evolutionary trajectories.The Poales have achieved global dominance via parallel evolution in open habitats, with notable, spatially and phylogenetically restricted divergences into strictly closed habitats.
