Dataset and analyses of global reptile bioregions

Dataset and scripts used to run the analyses of global reptile bioregions and the comparison among regionalisations of different vertebrate grooups. <br> The dataset contains the following files: <br> - "Reptile distribution &amp; phylogeny.Rdata": Rdata file containing four objects. 1) "comm": matrix of reptile species presence in 200 x 200 km cells across the globe; 2) "coo": coordinate of centroids of the 200 x 200 km cells; 3) "tree": phylogeny for the 9016 reptile species included in this study; 4) "coastline": global coastline used to refine the output of analyses of raster data. Species ranges were retreived from an updated version (1.5) of the "Global Assessment of Reptile Distributions" [Roll, U. et al. The global distribution of tetrapods reveals a need for targeted reptile conservation. Nat. Ecol. Evol. 1, 1677–1682 (2017)]. Phylogenetic data were retrieved from an inference-based phylogenetic tree [Tonini, J. F. R., Beard, K. H., Ferreira, R. B., Jetz, W. &amp; Pyron, R. A. Fully-sampled phylogenies of squamates reveal evolutionary patterns in threat status. Biol. Conserv. 204, 23–31 (2016)]. <br> - "Defining global reptile bioregions.R": script used to define global reptile bioregions. It includes a modified version of the "phylo.beta.pair()" function (R package "betapart"), that avoids the need of huge amount of RAM and allows a more efficient calculation of philogenetic beta diversity by identifying duplicate communities and running calculations in parallel. To run, this script needs "Reptile distribution &amp; phylogeny.Rdata". <br> - "Bioregions.zip": Bioregions of the different vertebrate groups compared in the current work (reptile, amphibians, birds, mammals) in shapefile format. For each group, we provide two shapefiles, showing realms and regions. <br> - "Random regions example.R": Script of example to test the significance of V-measure values through null-models. The example is performed on shallow regions, but the same script can be applied to any regionalisation. To run, this script needs "Bioregions.zip" to be extracted in the working directory.
