Geographic distribution of C₄ species and its phylogenetic structure across China.

ABSTRACT: Over the past fifty years, the distribution patterns of C₄ species, across large spatial scales, are largely ignored. Here, we endeavored to examine patterns in the taxonomic and phylogenetic diversity of species with C₄ photosynthetic pathways across the broad spatial extent of China and relate those to climatic gradients. We built a database of all plants with the C₄ photosynthetic pathway in China. We analyzed the geographic distributions, taxonomic diversity, phylogenetic diversity, and phylogenetic structure of all C₄ species, as well as the three families with the most C₄ species (Poaceae, Amaranthaceae and Cyperaceae), and compared their values along temperature and precipitation gradients at two scales-the level of the province
