This book was released on 2010 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Following retreat of the last glacial advance in the early 1700s, pink salmon Oncorhynchus gorbuscha colonized many watersheds in Glacier Bay, Alaska. Streams in the lower Bay were populated first, and colonization proceeded up the Bay during the last 200 years. The objective of this study was to use analyses of genetic data-microsatellite and allozyme loci, and mitochondrial DNA haplotypes--to elucidate the colonization mechanism. The even- and odd-year broodlines served as replicate experiments; the mechanisms of colonization for the two broodlines were similar in most respects. The population genetic structure, based on allele/haplotype frequencies and genetic diversity (FsT), suggested that in general, deglaciated streams were populated by colonists from nearby locations. The populations in lower Glacier Bay were likely established by colonists from populations outside Glacier Bay. In turn, the lower Bay populations contributed colonists to populations farther up the Bay, which subsequently provided colonists to the most recently deglaciated locations in the upper Bay, although in the even-year there appeared to be some contribution to the youngest populations from older Populations, outside of or in lower Glacier Bay. Few genetically divergent donor sources contributed colonists based on the limited linkage disequilibrium, higher relatedness, and lower allelic diversity within Glacier Bay populations. The number of fish involved in initial colonization was not large, based on slightly reduced genetic diversity within Glacier Bay, but minimal founder effect signals precluded very small numbers of fish as well. Most of the genetic variation appeared early in the formation of populations and effective population size estimates were >100 fish in every population. Some gene flow after initial colonization is supported by the increased allelic diversity and decline in relatedness with population age, but heterogeneity within Glacier Bay suggested that gene flow must be limited among some populations. Colonization of the youngest streams coincided with the historically high abundance of pink salmon in Southeast Alaska during the 1990s; I speculate that the rapid expansion in the size of these Populations subsequent to this study was the result of high survival rather than extensive gene flow"--Leaf iii.

Manhard and published by . This book was released on 2016 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon form distinct, locally adapted populations because of the spatial and temporal precision with which they home to their natal streams. Local adaptation is recognized as an important component underlying the productivity and sustainability of salmonid populations, yet there remains uncertainty of the scale at which it occurs. This uncertainty was addressed by analysis of demographic, genetic, and experimental data collected from seasonally structured brood lines of Pink Salmon that spawn in Auke Creek, Alaska. An extensive background of research on this system has indicated that the timing of the adult and juvenile migrations is closely aligned with fitness and productivity in this stream; this background provided a framework for synthesizing the results of the analyses to address these questions: (1) What ecological factors influence productivity of the freshwater and marine life history stages; (2) Do these factors suggest a mechanism for evolution of migration time; (3) What are the consequences of disrupting fine-scale local adaptation of migration time? Freshwater productivity appeared to be influenced primarily by competition for spawning habitat, rather than variability in environmental conditions. Marine productivity, conversely, was associated with physical processes that influence survival of juveniles in the nearshore environment. Consistent with these findings, genetic evolution of earlier migration time, which was observed in both adults and juveniles over two generations, appeared to be driven by earlier vernal warming of the nearshore environment. Despite these environmental changes and resulting selection against late migrating fish, recruitment to Auke Creek has remained stable, thereby indicating that seasonal structure of migration time has supported sustained productivity in a changing climate. Experimental relaxation of natural barriers to gene flow that maintain the seasonal structure resulted in intermediate adult migration times in two generations of hybrid fish. These patterns were consistent with an additive genetic basis for migration time and suggest that ecological outbreeding depression is a post-zygotic mechanism that maintains adaptive variation of migration time in Auke Creek. Collectively, these results provide evidence that fine-scale local adaptation can enhance productivity of salmonid populations while providing resilience to climate change.
Book Synopsis The Genetic Structure of Chinook and Coho Salmon Populations in California, with a Note on the Genetic Variability in Sturgeon (Acipenseridae). by : Devin Michael Bartley
Download or read book The Genetic Structure of Chinook and Coho Salmon Populations in California, with a Note on the Genetic Variability in Sturgeon (Acipenseridae). written by Devin Michael Bartley and published by . This book was released on 1987 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Populations of chinook, Oncorhynchus tshawytscha, and coho salmon, O. kisutch, from Northern California and four species of North American sturgeon were analyzed by horizontal starch-gel electrophoresis. The products of 53 gene loci from 27 enzyme systems were used to characterize the genetic structure of 35 groups of hatchery and wild chinook salmon. The distribution of specific alleles, cluster analysis based on genetic identities, analyses of gene flow, and gene diversity analyses indicated that groups of chinook salmon from the three major river drainages in California were genetically differentiated. The products of 45 gene loci from 21 enzyme systems were used to characterize the genetic structure of 27 groups of coho salmon. Most of the observed genetic variation was due to rare alleles occurring in only a few groups of salmon. No obvious association of specific alleles with geographic area was observed and the low level of genetic variability made patterns of genetic structure or associations among the groups of coho salmon difficult to determine. The application of biochemical-genetic analyses to the management of chinook and coho salmon fisheries was addressed. A comparison of hatchery groups of chinook and coho salmon with wild groups in the same area revealed that hatchery stocks generally reflect the genetic structure of the local populations. The genetic differentiation of chinook salmon by drainage could provide fishery scientists with a means to identify specific groups of chinook salmon. The application of this technique to manage coho salmon populations is problematic at the present given the seemingly random distribution of alleles and the low levels of genetic variability. The products of seven gene loci were used to identify hybridization between chinook and coho salmon in a collection of salmon from a tributary to the Trinity River. The implications of a group of hybrid fish in the wild were discussed in terms of genetic resource conservation and disease transmission. The products of 20 gene loci were used to characterize the genetic structure and relationship of four species of sturgeon: Acipenser transmontanus, A. medirostris, A. fulvescens, and A. brevirostrum. Fixed allelic differences existed among the four species at several gene loci and each species could be unambiguously identified by its genetic profile.
