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.
