dc.description.abstract | Bowhead whales, Balaena mysticetus, are large baleen whales that are
characterized by an Arctic distribution. In order to provide proper management
recommendations to the International Whaling Commission, a panel of twenty-five
microsatellite markers was developed. This panel consisted of pure cytosine-adenine
(CA) repeats and was selected for their ability to consistently amplify and for their
consistency for allele designations. This panel was utilized to investigate stock structure
within the Bering-Chukchi-Beaufort population of bowheads. Over thirty reports and
manuscripts utilized these data for providing management recommendations to the
International Whaling Commision.
From this work it was concluded that there is presently one stock of bowhead
whales within the Bering-Chukchi-Beaufort seas. This data was also utilized to examine
the genetic relationships of the remaining extant bowhead populations. The
microsatellite data, in combination with sequences from the mitochondrial control region
and the NADH dehydrogenase subunit 1 (ND1) region, were used to examine population
structure. The Okhotsk Sea was identified as the most divergent population of bowheads.
Relationships among the extant populations demonstrated high levels of effective gene flow between populations. Gene flow appeared to be female-biased in relation to the
Okhotsk Sea, whereas gene flow between Canada and the Bering-Chukchi-Beaufort
populations appears to be equal between the bowhead whale sexes. | en |
