Figure 1. Posterior distributions of selection intensity for the threeGalerucella species (A. G. tenella , B. G. pusilla , C. G. calmariensis ) (Blue, 95% CI<0, Yellow, 95% CI>0, dotted line = zero selection intensity).
Figure 2. Manhattan plot of haplotype frequency distortion across the genome for three beetle species. Y-axis in each plot is a measure of positive selection, captured by L, a measure of the haplotype frequency distortion. Chromosomes are coloured in alternatingly light and dark grey. Outlier loci (red) were calculated as being more than 4 standard deviations above the mean. Loci on autosomes and sex chromosomes for each species’ scaffolds are plotted relative to the beetleLochmaea crataegi , from a sister genus.
Figure 3. Histograms of the widths of identified sweep haplotypes in the genome of 3 species. a. A plot of the width all sweep haplotypes (significant and non-sig.; all dots in Fig. 2). b. A plot of only haplotypes whose frequency was significantly different from the mean (red dots in Fig. 2).
