Figures and tables

Fig. 1. Carex group laevigata species distribution and chromosome number reports for the specimens included in the study. The dashed lines represent the tentative distributions of the two lineages of C. binervis hypothesized by the phylogenetic analysis (Eurosiberian vs. strictly Mediterranean). Distribution of the main lineages is shown next to the tree.
Fig. 2. RAD-seq phylogeny of 152 samples of C. gr.laevigata and one sample of C. mairei (the three outgroup samples were dropped) based on 1761 loci and 10138 SNPs filtered from IQTREE analysis.
Fig. 3. The RDA analysis. (a) Dots represent the coordinates of populations in the biplot of the first two RDA axes and dot colors represent Carex species. (b) Dots represent the coordinates of SNPs in the biplot of the first two RDA axes and dot colors represent environmental predictors showing the highest correlation values with outlier SNPs. The projection of environmental predictors used in the RDA analysis is also displayed.
