Figure 5 : Genotype-environment association analysis between the
five retained environmental variables and a set of 1,320,367 unlinked
SNPs in North Atlantic Harbour porpoises, coloured by sampling locality.
(a) RDA biplot of the dataset without BLS samples; the overall model was
significant (p =0.001), the environmental variables explained
8.5% of the variance. SST, SSS and SCV were significant (b) pRDA biplot
of the dataset without BLS, the overall model was also significant
(p =0.001), the spatial and environmental variables explained
~5% and ~8% of the variance,
respectively. SSS and SCV were significant. sst_Mean (mean sea surface
temperature), sss_Mean (mean sea surface salinity), scv_Min (minimum
sea current velocity), sca_Min (minimum sea chlorophyll-A
concentration) and spp_Min (minimum sea primary productivity).
