Introduction clusters and sites where house sparrows were collected and screened for variation in DNA methylation. (The number of individuals screened for variation in DNA methylation/genetic variation is represented by N_epi/N_G. Epigenetic diversity is shown as haplotype diversity (epi-h) and percentage of polymorphic loci (%Poly), and genetic diversity is shown as expected heterozygosity (He), the mean number of alleles detected in an introduction cluster (Na)-indicated by an asterisk, and mean allelic richness within a site (Ar).)
