摘要
Molecular phylogenies using mitochondrial DNA and nuclear alleles of the lactate dehydrogenase B locus were found to be concordant for populations of Fundulus heteroclitus ranging from Canada to Florida. Both mitochondrial DNA and lactate dehydrogenase alleles show a clear separation between the northern individuals (from Nova Scotia and Maine) and the southern ones (from Georgia and Florida), with a mixed population found in the geographic intermediate (New Jersey). An historical isolation, possibly as ancient as 0.5-1 million years old, may have played a role in shaping the situation observed today.
