Book excerpt: This report summarises results of an examination of the utility of restriction fragment length polymorphisms (RFLPs) to detect genetic variability in mitochondrial DNA (mtDNA) among stocks of Arctic char (Salvelinus alpinus). The report also includes laboratory protocols which have been adapted during the investigation. The researchers conducted a survey using 20 restriction endonuclease enzymes on 60 frozen samples of Arctic char from Lake Hazen, Craig Lake, and central Ellesmere Island in the Northwest Territories to determine the existence of polymorphisms in mtDNA and to assess whether RFLPs could be used to distinguish stocks in local geographical areas. A subset of five endonuclease enzymes was used to examine fresh samples of hatchery lineages of Arctic char originally from Storvatn in northern Norway, from Labrador, and from two locations in the Northwest Territories. This was done to increase the geographic area examined in the search for genetic variability.

This book was released on 2002 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The amount of genetic variation in aquaculture strains of North American Arctic charr (Salvelinus alpinus) was compared to that in natural populations using six microsatellite markers. Aquaculture strains originating from the Fraser River (Labrador), Nauyuk Lake and Tree River (Nunavut), and Lake Aleknagik (Alaska) showed less genetic variability than their wild source populations in terms of allelic diversity. but not necessarily in observed heterozygosity. Pairwise tests for genetic differentiation between populations were significant for all but three comparisons. These comparisons consisted of consecutive year classes of cultured Labrador and Nauyuk fish originating from the same wild collections. A neighbour joining tree based on microsatellite data grouped samples according to their geographic origin. Phylogenetic analysis of mitochondrial control region sequences from S.alpinus-S.malma did not always group samples thought to be conspecific. These results indicate that all hatchery strains and wild populations of Arctic charr- should not be considered equal and that small founding population sizes have contributed to reduced genetic variation in aquaculture strains"--Leaf before i.

This book was released on 2005-11-24 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population and evolutionary genetics have been quickly developing ?elds of biological research over the past decades. This book compiles our current understanding of genetic processes in natural populations. In addition, the book provides the author’s original ideas and concepts based on the data obtained by himself and his close coworkers. The author introduces his pioneering concept of population genetic stability,and much of thebook is concerned with the factors and conditions of such stability. Why does genetic stability matter so much? Altukhov argues that the sustainable use of natural resources, including genetic resources of popu- tions, critically depends on the maintenance of their stability. The preser- tion of well-adapted genetic characteristics from one generation to the next is essential for this stability. Traditionally, population genetics has been - cusedonevolution andthe role of evolutionary factorsinshapinggenetic structures of populations. While the idea of a population as a dynamic unit of evolution has been widely accepted, the signi?cance of genetic stability and its implications for the long-term survival of populations and species have not been fully appreciated.
