Book Population Viability of Arctic Grayling Thymallus Arcticus in the Gibbon River Yellowstone National Park

Download or read book Population Viability of Arctic Grayling Thymallus Arcticus in the Gibbon River Yellowstone National Park written by Amber Christine Steed and published by . This book was released on 2007 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fluvial Arctic grayling Thymallus arcticus is restricted to less than 5% of its native range in the contiguous United States and was listed as Category 3 under the Endangered Species Act (ESA) until a 2007 ruling removed its protection. Fluvial grayling were thought to be restricted to the Big Hole River, Montana, where abundances were declining. Although fluvial grayling of the lower Gibbon River, Yellowstone National Park (YNP) were considered extirpated by 1935, anglers frequently reported catching grayling throughout the river since 1980. My goal was to determine if a viable population of fluvial grayling persisted in the Gibbon River, or if fish caught in the river were downstream emigrants from lacustrine populations in headwater lakes. I developed three objectives to address this goal: 1) determine grayling abundances in the Gibbon River, 2) determine the source of grayling in the Gibbon River detected downstream of headwater lakes (occupied by lacustrine populations), and 3) determine if grayling are successfully spawning in the Gibbon River.

Book Mitochondrial and Microsatellite DNA Diversity Throughout the Range of a Cold Adapted Freshwater Salmonid

Download or read book Mitochondrial and Microsatellite DNA Diversity Throughout the Range of a Cold Adapted Freshwater Salmonid written by and published by . This book was released on 2001 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the Pleistocene, isolation of groups of fish into distinct glacial refugia provided the opportunity for genetic divergence. This report examines the signature of such isolation & post-glacial range expansion in the Arctic grayling by assaying mitochondrial & microsatellite (nuclear) DNA variation throughout the North American range of the species. It also examines local population structure in the Peace River, British Columbia, since local demographics are integral to a species' phylogeographic structure. Genetic similarities among regions suggest that Arctic grayling survived glaciation in several refugia and the geographic dispersion & population establishment of a number of grayling lineages is proposed. Implications of the findings for conservation of the species are discussed.

Book Conservation and the Genetics of Populations

Download or read book Conservation and the Genetics of Populations written by Fred W. Allendorf and published by John Wiley & Sons. This book was released on 2012-12-17 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Loss of biodiversity is among the greatest problems facing the world today. Conservation and the Genetics of Populations gives a comprehensive overview of the essential background, concepts, and tools needed to understand how genetic information can be used to conserve species threatened with extinction, and to manage species of ecological or commercial importance. New molecular techniques, statistical methods, and computer programs, genetic principles, and methods are becoming increasingly useful in the conservation of biological diversity. Using a balance of data and theory, coupled with basic and applied research examples, this book examines genetic and phenotypic variation in natural populations, the principles and mechanisms of evolutionary change, the interpretation of genetic data from natural populations, and how these can be applied to conservation. The book includes examples from plants, animals, and microbes in wild and captive populations. This second edition contains new chapters on Climate Change and Exploited Populations as well as new sections on genomics, genetic monitoring, emerging diseases, metagenomics, and more. One-third of the references in this edition were published after the first edition. Each of the 22 chapters and the statistical appendix have a Guest Box written by an expert in that particular topic (including James Crow, Louis Bernatchez, Loren Rieseberg, Rick Shine, and Lisette Waits). This book is essential for advanced undergraduate and graduate students of conservation genetics, natural resource management, and conservation biology, as well as professional conservation biologists working for wildlife and habitat management agencies.

Book Evolutionary Genetics of Fishes

Download or read book Evolutionary Genetics of Fishes written by Bruce Turner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 651 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is my hope that this collection of reviews can be profitably read by all who are interested in evolutionary biology. However, I would like to specifically target it for two disparate groups of biologists seldom men tioned in the same sentence, classical ichthyologists and molecular biologists. Since classical times, and perhaps even before, ichthyologists have stood in awe at the tremendous diversity of fishes. The bulk of effort in the field has always been directed toward understanding this diversity, i. e. , extracting from it a coherent picture of evolutionary processes and lineages. This effort has, in turn, always been overwhelmingly based upon morphological comparisons. The practical advantages of such compari sons, especially the ease with which morphological data can be had from preserved museum specimens, are manifold. But considered objectively (outside its context of "tradition"), morphological analysis alone is a poor tool for probing evolutionary processes or elucidating relationships. The concepts of "relationship" and of "evolution" are inherently genetic ones, and the genetic bases of morphological traits are seldom known in detail and frequently unknown entirely. Earlier in this century, several workers, notably Gordon, Kosswig, Schmidt, and, in his salad years, Carl Hubbs, pioneered the application of genetic techniques and modes of reasoning to ichthyology. While certain that most contemporary ichth yologists are familiar with this body of work, I am almost equally certain that few of them regard it as pertinent to their own efforts.

Book Genetic Management of Fragmented Animal and Plant Populations

Download or read book Genetic Management of Fragmented Animal and Plant Populations written by Richard Frankham and published by Oxford University Press. This book was released on 2017 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby isolating them yet further and dooming many to eventual extinction Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.

Book Climate induced Habitat Fragmentation Affects Metapopulation Structure of Arctic Grayling in Tundra Streams

Download or read book Climate induced Habitat Fragmentation Affects Metapopulation Structure of Arctic Grayling in Tundra Streams written by Heidi E Golden and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is altering ecosystems across the globe, with ecological and evolutionary consequences affecting species persistence and biodiversity. I investigated the effects of changing hydrology on Arctic grayling (Thymallus arcticus) metapopulation structure, microgeographic differentiation, movement patterns and vital rates using neutral genetic microsatellite markers, remote sensing of PIT-tagged individuals, body condition and ovarian histology. Arctic grayling within the study area on Alaska’s North Slope comprised five distinct genetic clusters. River distance and dry zones were significant factors explaining genetic differentiation among locations. Migration was low and asymmetrical among genetic clusters, but higher from headwater populations to the large coastal population than contrariwise. Adult Arctic grayling spawning movement patterns strongly associated with microgeographic neutral genetic differentiation within two watersheds. Following drought, I found significant differences in fall movement patterns and subsequent increased mortality of detained versus non-detained fish. My research on Arctic grayling underscores the significance of maintaining habitat connectivity for metapopulation persistence and the importance of including connectivity in conservation and management models to help mitigate the effects of climate change on species extinctions.
