Figure Lengend Snippet: Potential distribution of Centaurea gadorensis drawn with MAXENT. Top left, topographic map showing the location of genetically studied populations of C. gadorensis (full circles), C. pulvinata (stars) and C. sagredoi (squares). Additional presence records of C. gadorensis used for ecological niche modeling (ENM) are shown in empty circles. Top right, at the present time; bottom left, at the Last Glacial Maximum (LGM, ca. 21,000 years BP) using the Community Climate System Model (CCSM); bottom right, at the LGM using the Model of Max Planck Institute for Meteorology (MPI-ESM). Black dots indicate current populations of the species, whereas the dashed line shows the present coastline. The probability of presence is shown as continuous values from the threshold (defined as Maximum Sensitivity plus Specificity) to 1. This figure has been generated with ARCGIS.

Article Snippet: We extracted values for each variable at every locality using ARCGIS v10.2 (ESRI, Redlands, CA, United States), performed principal components analyses with the prcomp function and “scale = TRUE” in R, and calculated the distances between populations using the dist function in R. MMRR analysis was implemented using the MMRR function in R ( ).
