a Global FST values (top 1%, red lines) between two population pairs: northern vs. southern (up) and middle vs. southern (bottom). b Global Tajima’s D values in northern (up), middle (middle) and southern (bottom) populations. c Expression of genes under selection exposed to thermal (6 h at 37 °C) and high-salinity (7 days at 60‰) challenges. Asterisks indicate significant difference (*p < 0.05, **p < 0.01). The blue-to-yellow color bar represents the relative expression level of the given gene from low to high.
