Mitochondrial DNA Sequence Variation in Saugers
Abstract Despite extensive work documenting genetic variation in walleyes Sander vitreus , relatively little is known about the distribution of variation in saugers S. canadensis . Mitochondrial DNA sequence variation was surveyed among samples of saugers to assess the magnitude and distribution of...

There was no evidence of multiple refugia within which sauger populations could have differentiated. A single Mississippian refuge is consistent with the data and with likely routes of colonization of the Great Lakes–St. Lawrence River and the Hudson Bay drainage. A mismatch distribution analysis among haplotypes suggested a recent population expansion; the presence of haplotypes with broad distributions is also consistent with a recent range expansion.
