A total of 17,260 species occurrence data spanning more than 200 species and infraspecific taxa and all 26 genera, were assembled to generate the Caesalpinia Group distribution maps. Vouchered occurrence records (Basis of Record: Preserved Specimen) were downloaded from the Global Biodiversity Information Facility (GBIF; (June 2017), SEINet (http://swbiodiversity.org/seinet/) and DryFlor (http://www.dryflor.info/). To improve accuracy, the distribution of each species was mapped and checked against monographs or expert knowledge, and obvious outliers removed. Occurrence points located in the sea, in botanical gardens, on the centroid of a country, or with coordinates only at the level of degrees, were removed. Data handling was performed in R (R Core Team, 2018). This dataset was generated as part of the following publication: Gagnon, E., Ringelberg, J., Lewis, G.P., Bruneau, A. & Hughes, C.E. (2018; accepted, pending revisions) Global Succulent Biome phylogenetic conservatism across the pantropical Caesalpinia Group (Leguminosae). New Phytologist.

Данные проекта
The extent to which phylogenetic biome conservatism versus biome shifting determine global patterns of biodiversity remains poorly understood. To address this question, we investigate the biogeography and trajectories of biome and growth form evolution across the Caesalpinia Group (Leguminosae), a clade of 225 species of trees, shrubs and lianas distributed across the Rainforest, Succulent, Temperate and Savanna Biomes. We focus especially on the little-known Succulent Biome, an assemblage of succulent-rich, grass-poor, seasonally dry tropical vegetation distributed disjunctly across the Neotropics, Africa, Arabia and Madagascar. We reconstruct a time-calibrated phylogeny, assemble species occurrence data, and assign species to areas, biomes and growth forms. These data are used to estimate the frequency of trans-continental disjunctions, biome shifts and evolutionary transitions between growth forms and test for phylogenetic biome conservatism and correlated evolution of growth forms and biome shifts. We uncover a pattern of strong phylogenetic Succulent Biome conservatism. We show that trans-continental disjunctions confined within the Succulent Biome are frequent and that biome shifts to the Savanna, Rainforest and Temperate Biomes are infrequent and closely associated with shifts in plant growth forms. Our results suggest that the Succulent Biome comprises a tightly constrained evolutionary arena spanning large geographical disjunctions across the tropics.
