The role of geography, ecology, and hybridisation in the evolutionary history of Canary Island Descurainia

GPS coordinates were taken from 216 Canary Island <em>Descurainia</em> herbarium specimens held at the Natural History Museum, London. Climatic variables for these localities were obtained from WorldClim v.2.1 (years 1970-2000; Fick &amp; Hijmans, 2017), using 19 bioclimatic (biolcim) variables derived from temperature and rainfall values at a spatial resolution of 30 seconds (~1 km²). The GIS datasets were used to interpolate climate values for all individuals using ArcMap and the means for each bioclimatic variable per species were calculated. The <em>pairs</em> function in R was used to identify correlated variables. Where correlated variables were identified, the one that explained the largest differences between species was retained for further analysis. The data in this file are only those retained.
