Nucleotide diversity (a) and site frequency spectrum (b) of five populations of Ae. aegypti.
a Nucleotide diversity (π) was estimated for non-coding sites >500 bp from exons. b The site frequency spectrum was estimated for 10 individuals from each population using third codon positions and non-coding sites >100 bp from exons. Ae. bromeliae was used to polarize sites. The grey bars are the expected frequencies assuming variant sites are neutral and the effective population size is constant. In both panels, error bars are 95% confidence intervals from block-bootstrapping
