Spatial phylogenetics of the native woody plant species in Hainan, China.

摘要: To better identify biodiversity hotspots for conservation on Hainan Island, a tropical island in southern China, we assessed spatial variation phylogenetic diversity and species richness using 18,976 georeferenced specimen records newly reconstructed molecular phylogeny of 957 native woody plants. Within this framework, delineated bioregions based vegetation composition mapped areas neoendemism paleoendemism to priority conservation. Our results reveal that the southwest is most important hot spot endemism plant followed by southeast area. The distribution endemic showed scattered, rather than clustered, pattern island. Based range-weighted turnover metrics, three major vegetational zones Hainan. These largely correspond natural secondary growth managed forests (e.g., rubber timber forests) central Hainan, old-growth forest at margins nature reserves Jianfeng Diaoluo National Nature Reserves). study helps elucidate potential botanical priorities within an evolutionary, framework.
