We investigated >67 K single nucleotide polymorphism (SNP) loci for signatures of local adaptation in 59 unrelated wolves (Canis lupus) from four previously identified population clusters and identified 353 candidate loci. The neighbouring megabase regions in the dog (C. lupus familiaris) genome included functional genes for e.g. temperature regulation that may indicate local adaptation and genes controlling for universally important functions, including olfaction, hearing, vision and cognition. Single nucleotide polymorphisms associated with universally important traits typically show marked differences in allele frequencies among population clusters, and parallel selection for features important to all wolves may eclipse local environmental selection and implies long-term separation among population clusters.
