Download or read book The Natural History of an Arctic Oil Field written by Joe C. Truett and published by Elsevier. This book was released on 2000-06-09 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of the harsh conditions that characterize the Arctic, it is a surprisingly fragile ecosystem. The exploration for oil in the Arctic over the past 30 years has had profound effects on the plants and animals that inhabit this frozen clime. The Natural History of an Arctic Oil Field synthesizes decades of research on these myriad impacts. Specialists with years of field experience have contributed to this volume to create the first widely available synopsis of the ecology and wildlife biology of animals and plants living in close association with an actively producing oil field. - First widely available synthesis of arctic oil field ecology and wildlife biology - Concise yet readable treatment of a diverse polar ecosystem - Useful for land managers, policy makers as well as ecologists, and population biologists - Chapters authored by recognized authorities and contributions are peer-reviewed for accuracy and scientific rigor - Illustrations attractively designed to enhance comprehension

Download or read book Genetic Variation in Cultured and Natural Populations of Arctic Charr Salvelinus Alpinus from North America microform written by Tricia Anne Lundrigan and published by National Library of Canada = Bibliothèque nationale du Canada. 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.

Download or read book Ecology behaviour and conservation of the charrs genus Salvelinus written by Pierre Magnan and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salvelinus species are one of the most thoroughly studied groups of fishes. Many reasons explain this intense interest in charr biology. Charrs have a Holarctic distribution encompassing many Asian, North American, and European countries and occupy diverse marine and freshwater environments. Furthermore, the current distribution of charr includes areas that were directly influenced by climate and topographic change associated with the many Pleistocene glaciations. Undoubtedly, these conditions have promoted much of the tremendous morphological, ecological, and genetic variability and plasticity within Salvelinus species and they make charr very good models to study evolutionary processes 'in action'. Many charr species also exhibit demographic characteristics such as slow growth, late maturity, and life in extreme environments, that may increase their susceptibility to extinction from habitat changes and overexploitation, especially in depauperate aquatic habitats. This vulnerability makes understanding their biology of great relevance to biodiversity and conservation. Finally, charr are of great cultural, commercial, and recreational significance to many communities, and their intimate linkage with human societies has stimulated much interest in this enigmatic genus. This volume comprises a selection of papers presented at the fourth International Charr Symposium held in Trois-Rivières (Québec, Canada), from 26 June to 1 July 2000. It includes 31 papers on ecological interactions and behaviour, trophic polymorphism, movement and migration, ecophysiology and evolutionary genetics, ecological parasitology, environmental stress and conservation. These studies cannot cover all recent developments in the ecology, behaviour and conservation of Salvelinus species, but collecting them into a special volume should bring attention to current research on this important genus and stimulate further work on Salvelinus species.

Download or read book Population Structure Genetic Diversity and Dispersal of Anadromous Arctic Char Salvelinus Alpinus in Frobisher Bay Nunavut Inferred from Microsatellite Markers written by Jean-Sébastien Moore and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genetic population structure of anadromous Arctic char from two river systems flowing into Frobisher Bay, Nunavut (the Sylvia Grinnell River and the Bay of Two Rivers) was investigated. A total of 495 individuals were genotyped at twelve microsatellite markers. Overall, our results support the presence of weak population structure among rivers in the Frobisher Bay region and suggest that the use of molecular tools to inform fishery management in this region may be helpful if appropriate sampling designs are implemented.
