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).
