Book Synopsis Genetics of Subpolar Fish and Invertebrates by : Anthony J. Gharrett
Download or read book Genetics of Subpolar Fish and Invertebrates written by Anthony J. Gharrett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries genetics researchers will find invaluable the thirty-eight peer-reviewed contributions in this book, presented at the 20th Lowell Wakefield Fisheries Symposium "Genetics of Subpolar Fish and Invertebrates," held in May 2002 in Juneau, Alaska. Looming over concerns of lost fisheries stocks and persistent erosion of genetic variability are predictions of global warming, which may further tax genetic resources. One consequence is an increased reliance on genetic applications to many aspects of fisheries management, aquaculture, and conservation. The contributions in this book are important to modern fisheries science and genetics, and illustrate the evolution of the field over the past decade. The improved technology provides tools to address increasingly complicated problems in traditional applications and ecological and behavioral studies. The union between molecular and quantitative genetics, where many of the major questions about population structure and evolution remain unanswered, will also benefit from the new technologies.

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.

Book Synopsis Conservation Biology by : Peggy L. Fiedler
Download or read book Conservation Biology written by Peggy L. Fiedler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Refecting what a new generation of conservation biologists is doing and thinking, this vital and far ranging second edition explores where conservation biology is heading. It challenges many conventions of conservation biology by exposing certain weaknesses of widely accepted principles. Combining contributions from both the school and the new breed of conservation biologists, this insightful text focuses primarily on topics the are integral to the daily activities of conservation biologists. Several chapters address ecosystem restoration and biotic invasions as well as the the mechanics of population viability analyses, which are now a routine facet of conservation efforts. A case history approach is implemented throughout the book, with the use of practical real-world examples. Furthermore, an in-depth look at quantitative analyses is presented, allowing for models and mathematical analyses to pinpoint limitations in existing data and guide research toward those aspects of biology that are most likely to be critical to the dynamics of a species or an ecosystem.

Book Synopsis Upstream by : National Research Council
Download or read book Upstream written by National Research Council and published by National Academies Press. This book was released on 1996-07-17 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwestâ€"economic, recreational, symbolicâ€"is enormous. Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runsâ€"and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problemâ€"starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including: Salmon biology and geographyâ€"their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activitiesâ€"grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issueâ€"policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest.
