Dataset of Phylogenetic classification of the world’s tropical forests. Identifying and explaining regional differences in tropical forest dynamics, structure, diversity, and composition are critical for anticipating region-specific responses to global environmental change. Floristic classifications are of fundamental importance for these efforts. Here we provide a global tropical forest classification that is explicitly based on community evolutionary similarity, resulting in identification of five major tropical forest regions and their relationships: ( i ) Indo-Pacific, ( ii ) Subtropical, ( iii ) African, ( iv ) American, and ( v ) Dry forests. African and American forests are grouped, reflecting their former western Gondwanan connection, while Indo-Pacific forests range from eastern Africa and Madagascar to Australia and the Pacific. The connection between northern-hemisphere Asian and American forests is confirmed, while Dry forests are identified as a single tropical biome.
The 406 locations with 20 or more species that were used in this study (contributor abbreviations given at end of table). Cluster assignment is given along with cluster success (percentage of times that each location was assigned to the same cluster based on 20 cluster analyses, each time with a different random set of 20 species per location). Environmental conditions represent the average for each location (1 x 1 degree latitude/longitude grid cell).
