This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study reexamines the nuclear microsatellite analysis by Rooney et al. (1999a) of Bering-Chukchi-Beaufort Seas bowhead whales (Balaena mysticetus) to determine if this population underwent a genetic bottleneck as a result of 19th and early 20th Century commercial whaling. This investigation used more accurate laboratory techniques to score alleles, had a larger sample size that was divided into two groups (mainland Alaska and St. Lawrence Island (SLI)), and used a moderately different set of microsatellite loci which are more variable and thus, more informative. The results corroborate the findings of Rooney et al. (1999a) for mainland Alaska showing no evidence of a genetic bottleneck. However, the SLI data analyses provide conflicting conclusions. The Wilcoxon test is significant for a heterozygote excess (p = 0.042) suggesting that a genetic bottleneck has occurred. This is not substantiated by the exact tests of each locus or the table-wide sign test. There is a possibility that a bottleneck has occurred, but due to the small sample size this is not a definitive conclusion and warrants reanalysis with a larger sample size.

This book was released on 1910 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first study of the behaviour and habitat preferences of bowhead whales ('Balaena mysticetus') in northern Foxe Basin, Nunavut, Canada. The study is divided into two parts; the first part examined the characteristics of bowhead habitat and the second part describes the behaviour of bowheads during the ice-edge season. Characteristics of bowhead habitat were identified by quantifying relationships between habitat variables (water depth, surface temperatures, ice conditions, and zooplankton densities) and the distribution of whales recorded during strip-transect surveys through a 4 x 4 km quadrat system, in July and August 1997. Two study areas were examined: "A" was examined in July (ice-edge season), when land-fast ice was present on the northern edge of the study area and "B" was examined in August (open-water season), when pack ice is present. Relationships between habitat variables and whale distribution were identified with Mantel tests. The second part of the study examined the behavior of bowheads during the ice-edge.

Book excerpt: The hunt is co-managed by the Nunavut including northern Foxe Basin and Wildlife Management Board and the Canada Department of Fisheries and Oceans. [...] The Cosens and Blouw (1999) found that the species is currently listed as endangered by size range of females with calves in northern the Committee on the Status of Endangered Foxe Basin was similar to that in the Wildlife in Canada (COSEWIC). [...] Between 1979 and 2 Central and Arctic Hudson Bay/Foxe Basin Bowheads 1996, there was no licensed hunt of Baffin Bay-Davis Strait whales consist of bowheads in the Hudson Bay-Foxe Basin one stock and to determine the relationship stock. [...] If Cumberland Sound whales Foxe Basin and those around Repulse Bay are representative of the Baffin Bay-Davis belong to the same population and that these Strait population, then Hudson Bay-Foxe estimates could be added, giving a total Basin bowheads and Baffin Bay-Davis Strait estimate of about 345 bowheads in the stock. [...] This, in combination with the Aerial surveys have not sampled the conclusions of the Inuit Bowhead complete summering range of this stock and Knowledge Study, suggests that the stock underestimate total stock size.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This report documents changes in the summer range of the bowhead whale (Balaena mysticetus) throughout postglacial time, for the central Canadian Arctic between the Beaufort Sea and Baffin Bay, as compared to changes in frequency of penetration of boreal driftwood during the same time interval in the same area. Variations in Quaternary climate are also considered.

This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report of a three-year program, 2002 through 2004, to survey the numbers of bowhead whales summering in the Canadian eastern Arctic. The goals were to estimate numbers in both the putative Davis Strait-Baffin Bay (DS-BB) and Hudson Bay-Foxe Basin (HB-FB) stocks as well as to better understand the summering distribution of the bowhead whales. Data collection and data analysis methods are explained and results are cited by date and place. Tables and maps include details of bowhead whales distribution in Canada, near-surface estimates of bowhead whale numbers, numbers of whales seen by observers at various distances from aircraft in each of three surveys, and summary of survey conditions in 2002 and 2003.
