| 1 | Climatic niche evolution in Smilacaceae(Liliales)drives patterns of species diversification and richness between the Old and New World显示文摘Geographical variation in species richness in plant groups is determined by the interplay between historical,evolutionary,and ecological processes.However,the processes underlying the striking disparity in species richness between Asia and the Americas remain poorly understood.Here,we synthesize global phylogenetic and macroecological data on the diversification of Smilacaceae,deciphering potential drivers underlying the species diversity pattern biased toward Asia.We compiled global distributions of all Smilacaceae species,and reconstructed the biogeographic history and niche evolution using a new time-calibrated phylogeny(eight genes,135 species).Integrating these data sets,we estimated evolutionary histories and diversification rates for each region,and tested correlations among species diversification,niche evolution,and niche divergence.Smilacaceae probably originated during the Late Cretaceous/Early Palaeocene and began to diversify in middle to low latitudes in Central America and Eurasia during the Late Eocene.Both the Old and New World clades exhibited a steady,albeit slight,increase of species diversification from the Late Eocene to Early Miocene.However,the Old World clade experienced an abrupt increase in net diversification during the Late Miocene.Our findings also revealed that species diversification rates were positively correlated with ecological niche evolution and niche divergence.Niche shifts and climatic niche evolution since the Middle Miocene played crucial roles in species diversification dynamics within Smilacaceae.The high plant richness in Asia may be explained by greater diversification in this region,potentially promoted by heterogeneous environments. | Zhe-Chen Qi Pan Li Jun-Jie Wu Alexander Gamisch Tuo Yang Yun-Peng Zhao Wu-Qing Xu Shi-Chao Chen Kenneth M.Cameron Ying-Xiong Qiu Cheng-Xin Fu | 2023 | Journal of Systematics and Evolution2023，61，5： | 0 |
