Data from: Post-glacial recolonization of the North American Arctic by Arctic char (Salvelinus alpinus): genetic evidence of multiple northern refugia and hybridization between glacial lineages
Aims: We investigated post-glacial recolonization of the North American Arctic by Arctic char (Salvelinus alpinus) and examined potential hybridization between different glacial lineages upon secondary contact. Location: North American Arctic and adjacent areas. Methods: We collected mtDNA sequence...
