Stuart_etal_dataframes.RData
This R workspace image contains two dataframes, one for anoles and one for terraranans. Each data frame contains pairwise environmental dissimilarity and species turnover values for island and mainland sub regions. The columns are:

geo_dist: geographic distance between sampling areas
climelev.pc.dist: environmental distance between sampling areas from a pca on environmental variables and elevation
log.area.diff: the difference in log area between sampling areas
sor: Sorensen's index of species turnover
jac: jaccard's index
comp.type: Identifies measures as mainland-mainland (m.m), mainland-island (i.m), or island-island (i.i)
comp.nums: identifies the corresponding sampling areas, which are mapped in the accompanying ArcGIS grids in the Stuart_etal_sample_areas.zip file

Stuart_etal_sample_areas.zip
This compressed folder contains two ArcGIS grids: ter_m_i_samp (Terraranans) and an_m_i_samp (anoles). Each grid shows the mainland range of the relevant clade (values of 1.0), mainland sampled areas (50xxx) and islands included in the analysis(60xxx)
