This book was released on 2010 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the structure of intraspecific genetic and morphological diversity within and across habitats is a fundamental aspect of biodiversity research with conservation value. Atlin Lake is the largest lake in British Columbia, Canada, and contains relatively pristine populations of lake trout (Salvelinus namaycush) that are key components of the lake?s fish community and local fisheries. Lake trout from Atlin Lake were examined for genetic and phenotypic variation using eight microsatellite DNA loci, body form, and colouration. Genetic assays were also conducted on lake trout from the adjoining Tagish Lake and from 17 other localities to provide spatial context for the variation within Atlin Lake. The genetic data suggested that there were three genetic subpopulations within the Atlin?Tagish lake system. Morphological analysis identified two morphological groups of lake trout within Atlin Lake. Genetic and morphological groupings in Atlin Lake were not associated with each other. A mixed-stock analysis of samples collected from Atlin Lake commercial and recreational fisheries suggested that all genetic subpopulations contributed to the fishery and that there was some contribution from fish originating from within Tagish Lake.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the drivers of successful species invasions is important for conserving native biodiversity and for mitigating the economic impacts of introduced species. However, whole genome resolution investigations of the underlying contributions of neutral and adaptive genetic variation to successful colonization in introduced populations are rare. Increased propagule pressure should result in greater neutral genetic variation, while environmental differences should elicit selective pressures on introduced populations, potentially supporting greater adaptive genetic variation. We investigated neutral and adaptive variation among nine introduced brook trout (Salvelinus fontinalis) populations using whole-genome sequencing (28,490,618 SNPs based on pool-seq). The populations inhabit different, isolated lakes in western Canada and descend from a common source, with an average of ~19 (range of 7-41) generations since introduction. We found no evidence of bottleneck events nor strong evidence of purifying selection, and little support that varying propagule pressure or differences in local environments shaped neutral genetic variation. Putative outlier analysis revealed non-convergent patterns of adaptive differentiation among lakes with minimal outlier loci (0.001%-0.15%) which did not correspond with tested environmental variables, despite conditions that should facilitate stronger adaptive differentiation (e.g. abiotic and biotic environmental differences, propagule pressure differences). Our whole genome sequencing analysis provides an example of an introduction success not strongly influenced by genetic variation and suggests that observed differentiation among introduced salmonid populations can be idiosyncratic, population-specific, or stochastic.
Download or read book Population Differentiation of Ontario Lake Trout Salvelinus Namaycush Using the Major Histocompatibility Complex Class Ii beta Gene written by Steven Kuntz and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The lake trout (Salvelinus namaycush) is a coldwater salmonid with an extensive native distribution across formerly glaciated regions of North America. Lake trout are known to be a glacial 'relict' species and evolved as a result of glaciation events during the Pleistocene era. Historic and recent human activities along with climate change have had a significant influence on the phylogeographic and genetic compositions of current lake trout populations. Human activities like overexploitation, habitat degradation and most importantly stocking have had detrimental effects on the diversity and variability of populations within Ontario. Prior genetic studies of lake trout have used multiple neutral genetic marker systems including allozymes, microsatellites and mitochondrial DNA (mtDNA) to distinguish multiple glacial refugia and phylogeographic lineages within North America. This project differentiated lake trout populations within Ontario using a non-neutral marker, the major histocompatibility (MH) class II beta gene. A total of fifty-seven unique MH class II [beta]1 alleles were identified in 216 individual lake trout from ten lakes across Ontario and one in New York. Native, hatchery stocking sources and native but stocked lake trout populations were characterized for MH diversity and allelic states to assess their diversity and divergence. A geographic map of MH diversity within each lake was completed. Commonly stocked lakes within Ontario have shown a decreased amount of allelic diversity when compared to other populations. The introgression of MH class II beta alleles within the mixed-ancestry populations and the significance of adaptive genetic diversity within and among populations from different histories will be important for the management of lake trout facing future climatic and ecological conditions.

This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings. This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.
