Mitochondrial haplotype diversity among Portuguese brown trout Salmo trutta L. populations: relevance to the post‐Pleistocene recolonization of northern Europe
Abstract Mitochondrial haplotype diversity in seven Portuguese populations of brown trout, Salmo trutta L., was investigated by sequencing the 5′ end of the mitochondrial DNA (mtDNA) control region. Five new haplotypes were described for this species, each two to three mutational steps distant from...
