Book Synopsis Variation in Mitochondrial DNA and Allozymes Discriminates Early and Late Forms of Chinook Salmon (Oncorhynchus Tshawytscha) in the Kenai and Kasilof Rivers, Alaska by : Noah Swayambhu Adams
Download or read book Variation in Mitochondrial DNA and Allozymes Discriminates Early and Late Forms of Chinook Salmon (Oncorhynchus Tshawytscha) in the Kenai and Kasilof Rivers, Alaska written by Noah Swayambhu Adams and published by . This book was released on 1994 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic differences between early and late forms of Alaskan chinook salmon (Oncorhynchus tshawytscha) were identified using two genetic approaches: mitochondrial DNA (mtDNA) analysis and protein electrophoresis. The study populations consisted of early- and late-run chinook salmon in each of the Kenai and Kasilof rivers in Alaska, and a single population from the Minam River, Oregon, that provided a relative scale for the differences among the Alaskan populations. Two segments of mtDNA were amplified separately using the polymerase chain reaction (PCR) and then digested with 14 to 16 restriction enzymes. Results showed that the two early runs were genetically similar to each other but different from either of the late runs. The late runs were different from each other based on the frequency of the common haplotypes. The Minam River stock shared two haplotypes with the Alaskan stocks and displayed one unique haplotype. The frequency difference in the shared haplotypes together with the presence of a unique haplotype allowed us to separate the Oregon population from those in Alaska. In the protein analysis, each of the five populations was examined at 30 allozyme loci to determine variation within and between the runs. Based on 14 polymorphic loci, Minam River chinook salmon were genetically distinct from the Alaskan populations. Within the Alaskan populations, the two early runs were most similar to each other but different from the two late runs; the two late runs were also genetically most similar to each other. Based on all loci, protein electrophoresis proved to be a useful technique to separate stocks of chinook salmon. On a locus by locus basis, however, mtDNA was more powerful. Both mtDNA and allozyme analysis suggest that chinook salmon may segregate into genetically different early and late forms within a drainage.
Book Synopsis Evolution Illuminated by : Stephen C. Stearns
Download or read book Evolution Illuminated written by Stephen C. Stearns and published by Oxford University Press. This book was released on 2003-11-27 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will appeal to investigators in each of the scientific disciplines it integrates--evolutionary biology, ecology, salmonid biology, management, and conservation. Variation in salmonids can be used to illustrate virtually all evolutionary questions, and so the work will also attract general scientific interest by ecologists and evolutionary and conservation biologists.
Book Synopsis Salmonid Fishes by : Yuri P. Altukhov
Download or read book Salmonid Fishes written by Yuri P. Altukhov and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important title encompasses features of genetic processes in complexly organised population systems of salmonids, one of the most commercially valuable families of fish worldwide. Translated from the original work in Russian, the authors have taken the opportunity to update and revise the work, much of it appearing in the English language for the first time. Covering such important concepts as optimal gene diversity and the unfavourable influence of fishery and hatchery reproduction on the genetic structure of salmon populations, the authors have drawn together a huge wealth of information that will form the cornerstone of much new work in the future. The authors of Salmonid Fishes have between them many years of research experience and practical knowledge in the area and the English translation of this important work, which has been edited by Professor John Thorpe and Professor Gary Carvalho, provides vital information for all those involved in salmonid management, exploitation and conservation, including fish biologists, fisheries managers, conservation and population biologists, ecologists and geneticists.

Book Synopsis Development of Microsatellite Genetic Markers for Kenai River Chinook Salmon by : Robert N. Begich
Download or read book Development of Microsatellite Genetic Markers for Kenai River Chinook Salmon written by Robert N. Begich and published by . This book was released on 2010 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant genetic variation exists among populations of Chinook salmon from Kenai River drainage. Recent analyses using microsatellite markers confirm the results of the earlier studies which detected differences between early- and late-run Chinook salmon based on allozyme and mitochondrial DNA markers. This report presents the results of a survey of 13 microsatellite loci (from a standardized set used by the Pacific Salmon Commission Chinook Technical Committee) in 977 individual fish representing nine Chinook salmon populations in the drainage. Average genotyping failure rate was approximately 4.5%, with the majority of failures in the Slikok Creek collection (success rate ~ 35.9%) where samples mainly came from carcass sampling. Estimates of per-locus FST ranged from 0.019 to 0.045 suggesting a level of divergence among collections that should be useful for management applications. The populations in the baseline could be separated into four groups based on geographic, behavioral, and genetic characteristics: Lower Kenai River tributaries, Kenai River mainstem, Killey River, and Quartz Creek. Simulation results indicate that contributions from these groups can be detected in fishery harvests with a high degree of precision and accuracy (mean correct allocation = 96.7%).
