Figure 4: Manhattan plot of mean FSTbetween urban and forest populations along the Great tit genome for (A)
Barcelona, (B) Montpellier and (C) Warsaw. Dark orange (A), purple (B)
and light orange points (C) represent significant outlier SNPs
identified by the FST-outlier test Bayescan for each
population pair, given with their associated genes in 5 kb. Green points
represent outliers found with the multivariate RDA approach. A few SNPs
were identified by both the Bayescan and the RDA methods and signalled
as a green point circled with the colour used for the considered pair.
