Abstract：
China covers a vast territory harbouring a large number of aquatic plants. Although there are many studies on the 0 -diversity of total, herbaceous or woody plants in China and elsewhere, few studies have focused on aquatic plants. Here, we analyse a comprehensive data set of 889 aquatic angiosperm species in China, and explore the geographic patterns and climatic correlates of total taxonomic and phylogenetic 0 -diversity as well as their turnover and nestedness components. Our results show that geographic patterns of taxonomic and phylogenetic 0 -diversity are highly congruent for aquatic angiosperms, and taxonomic 0 -diversity is consistently higher than phylogenetic 0 -diversity. The ratio between the nest-edness component and total 0 -diversity is high in northwestern China and low in southeastern China. The geographic patterns of taxonomic and phylogenetic 0 -diversity of aquatic angiosperms in China are obviously affected by geographic and climatic distances, respectively. In conclusion, the geographic patterns of taxonomic and phylogenetic 0 -diversity of aquatic angiosperms are consistent across China. Climatic and geographic distances jointly affect the geographic patterns of 0 -diversity of aquatic an-giosperms. Overall, our work provides insight into understanding the large-scale patterns of aquatic angiosperm 0 -diversity, and is a critical addition to previous studies on the macroecological patterns of terrestrial organisms.Copyright (c) 2022 Kunming Institute of Botany, Chinese Academy of Sciences.
