Table 1 Ecological and genetic attributes of six A. thaliana populations. Ecological attributes encompass the percentage of vegetation types, including forest, scrubland and others (dry riverbeds, boulders, paths, and roads) across study areas. Estimates of above and belowground abundance are given by the mean (± SE) number of A. thaliana individuals observed or estimated in areas of ca. 20 m2. Genetic attributes include observed heterozygosity HO (± SE) based on 12 nuclear microsatellites (SSR), and the proportion of different and unique genotypes (represented by one individual only) estimated with whole-genome sequences (WGS). Genetic and ecological attributes allow the distinction of populations harboring low (AGU, BON, and CAI) and high (MAR, MDC, and POB) genotypic and ecological diversity in edge and core environments, respectively
