Book Synopsis Ecology, behaviour and conservation of the charrs, genus Salvelinus by : Pierre Magnan
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.

Book Synopsis Advances in Invertebrates and Fish Telemetry by : Jean Paul Lagardere
Download or read book Advances in Invertebrates and Fish Telemetry written by Jean Paul Lagardere and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a selection of the most significant papers presented at the Second Conference on Fish Telemetry in Europe in La Rochelle, France, in April 1997. The conference was attended by 100 scientists from 18 countries. The contributions are grouped under the following headings: Methodology and New Developments, Tagging Procedures, Behavioural and Physiological Ecology, Fish Migration, Stock Management and Conservation. Particular emphasis was put on tag miniaturisation, multiple functions and sampling strategies. Papers concerned the effects of tags on fish for consolidating behavioural or original physiological investigations noticeably more open to the marine environment. Methods were essentially applied to study the relationships between fish and their natural environment. Besides providing up-to-date information on the state of fish telemetry, the book illustrates the increase in spatial and temporal scales and the number of tracked fish which gives a statistical basis for field study in behavioural ecology.
Book Synopsis The Lake Charr Salvelinus namaycush: Biology, Ecology, Distribution, and Management by : Andrew M. Muir
Download or read book The Lake Charr Salvelinus namaycush: Biology, Ecology, Distribution, and Management written by Andrew M. Muir and published by Springer Nature. This book was released on 2021-03-03 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices used to ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.

Book Synopsis Migration of Freshwater Fishes by : Martyn Lucas
Download or read book Migration of Freshwater Fishes written by Martyn Lucas and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have increasingly demonstrated the widespread existence of spatio-temporal variations in the abundance and distribution of species of freshwater fishes, previously assumed not to move between habitats. These movements are often on a seasonal or ontogenetic basis, for spawning, feeding and refuge, and in many cases are fundamental for the successful completion of lifecycles. This important book provides a single source for a range of previously widely dispersed information on these movements of fish in fresh waters, covering potamodromous fishes as well as the more familiar diadromous species, worldwide. Contents include full descriptions of types of migration and spatial behaviour, the stimulus and capacity for fish to migrate, the effects of climate on patterns of migratory behaviour, a taxonomic analysis (mostly by family) of freshwater fish migration, methods for studying migration, and details of the impacts of man's activities on freshwater fish migration. Migration of Freshwater Fishes provides an excellent and comprehensive reference to which the river manager, biologist or student can now refer to obtain information, advice and current opinion on the migratory behaviour of most taxonomic groups of fishes occurring in fresh water. University libraries and aquatic research stations should also have copies of this essential reference book on their shelves. Well-known international authors. Of great commercial importance to fisheries and professional angling bodies. Draws together much new information in one place. Detailed review of world wide migratory behaviour for most groups of freshwater fishes. Pure and applied relevance, for academics, fisheries scientists, river managers and conservationists. This comprehensive book includes 67 tables and figures and over 1,400 references.

Book Synopsis World Small-scale Fisheries by : Ratana Chuenpagdee
Download or read book World Small-scale Fisheries written by Ratana Chuenpagdee and published by Eburon Uitgeverij B.V.. This book was released on 2011 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of fisheries is not lost in the global policy arena. What is often overlooked in the general discourse, however, is the significant difference between small-and large-scale fisheries. Major rethinking about all aspects of small-scale fisheries is required, including their contribution to catches, employment, livelihood, food security and conservation. This book is a collection of essays about the diverse, complex and dynamic contexts that characterize small-scale fisheries around the world. The essays highlight the strengths, capacity, motivation and contributions associated with this fishing sector. They remind us that solutions and opportunities for the viability and sustainability of small-scale fisheries can be found, once the issues are understood from a holistic perspective and possible options, including inventive governance arrangements, are fully explored. The authors are scientists and practitioners who work in small-scale fisheries in various parts of the world, many of whom participated at the first World Small-Scale Fisheries Congress (WSFC), held in Bangkok in October 2010, and are members of the global research network for the future of small-scale fisheries, Too Big To Ignore. The editor, Ratana Chuenpagdee, the initiator of the WSFC, is Canada Research Chair in Natural Resource Sustainability and Community Development at Memorial University of Newfoundland, Canada.

Book Synopsis Polar Lakes and Rivers by : Warwick F. Vincent
Download or read book Polar Lakes and Rivers written by Warwick F. Vincent and published by OUP Oxford. This book was released on 2008-09-11 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to describe the ecology of high latitude lakes, rivers and glacial environments in both the North and South polar regions. From the lake-rich floodplains of the Arctic to the deep, enigmatic waters of Lake Vostok, Antarctica, these regions contain some of the most extraordinary aquatic ecosystems on Earth. They provide a fascinating diversity of habitats for plant, animal and microbial communities, and are proving to be valuable model systems for exploring many ecological themes including landscape-lake interactions, adaptation of life to environmental extremes, and controls on the structure and functioning of aquatic ecosystems. Some of these waters also have direct global implications, including permafrost thaw lakes as sources of greenhouse gases, subglacial aquatic environments as a storehouse of ancient microbes, and Arctic rivers as major inputs of freshwater and organic carbon to the World Ocean. Given that many polar areas are experiencing greater climate warming than at lower latitudes, these ecosystems can also be viewed as sentinels of global change. This timely volume brings together many of the world's leading researchers in polar limnology to describe these diverse aquatic environments and their ecology. It introduces each major ecosystem type, examines the similarities and differences between Arctic and Antarctic systems as well as their responses to environmental change, and describes new frontiers for future research. A glossary of terms is provided for non-specialists, and a set of colour plates introduces the ecosystems and their biota. Polar Lakes and Rivers will be of value to students and specialist researchers alike, as well as to those with a more general interest in aquatic ecology, polar environments or global change who require an authoritative overview of this fast emerging topic.
