Spatial phylogenetic analyses combine phylogenies and spatial data at any taxonomic and geographic level. All studies to date have concentrated on either a particular taxonomic group, for example Australian Acacia, or the flora of a particular geographic region, for example analyses on the flora of Australia, California, or Chile. The recent PAFTOL angiosperm phylogeny created the opportunity to make a spatial phylogenetic world analysis at the genus level. We cleaned institutional plant records stored in the Global Biodiversity Information Facility (GBIF) to reflect the worldwide native range of each species (over 200000 species), then combined them into the PAFTOL genera. The final spatial dataset contained over 23 million records and was projected using World Mollweide at 50 50 km grid cells. The PAFTOL tree and spatial data were combined using Biodiverse to make diversity analyses and randomisations for CANAPE, Relative Phylogenetic Diversity and Phylogenetic Diversity tests. The results of two spatial phylogenetic analyses will be presented, one using a PAFTOL phylogram and one using a PAFTOL chronogram. We will also present comparisons of results against climatic variables and the biodiversity hotspots of the world. We will particularly focus on the Mediterranean-climate regions of the world and compare the world-analysis results with what has been found previously when analyses have just focussed on one particular area.
