Table 2 Descriptive statistics from genome-wide Pool-seq data (window size = 5,000 bp and fraction depth covered ≥ 0.8 i.e. a window was only retained if at least 80% of its SNPs had a read depth between 20X and 150X) for each of the two demes in Lakes Bunnersjöarna.π  = nucleotide diversity (Tajima, 1983),T D = Tajima’s D (Tajima, 1989),Ɵ  = Watterson’s theta (Watterson, 1975).
