Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
Download or read book Freshwater Fishes of Manitoba written by Kenneth Stewart and published by Univ. of Manitoba Press. This book was released on 2004-05-03 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manitoba’s ninety-three species of fish give the province the third most diverse fish population in Canada. The province’s variety of geological features, with its major lakes, rivers, tributaries, and watersheds, is due in large part to its history as the basin for Glacial Lake Agassiz. This, combined with its access to the waters of Hudson Bay and large American river systems, has provided habitat for a wide diversity of freshwater fish. Species from lampreys to goldeye, catfish to perch, bigmouth bass to slimy sculpin swim in waters from arctic rivers in the north to Red River tributaries and down to the Mississippi in the south. Freshwater Fishes of Manitoba is a comprehensive, user-friendly guide. Each species is accurately depicted in detailed colour photographs and accompanying map, with descriptions of physical characteristics, spawning and feeding habits, distribution, habitat, ecological role, and economic importance. The guide also includes an extensive glossary, keys to identifying the families, species, and subspecies, and information on documentation and preservation of specimens. Freshwater Fishes of Manitoba is not only the definitive guide to these fishes of Manitoba, it is also accessible and reliable for a range of users from general fishers to professional fish biologists.

Download or read book Living in Groups written by Jens Krause and published by Oxford University Press. This book was released on 2002-10-10 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shoals, swarms, flocks, herds--group formation is a widespread phenomenon in animal populations. It raises several interesting questions for behavioral ecologists. Why do animals form and live in groups, and what factors influence the ways in which they do this? What are the costs and benefits to an animal of group living? How are these influenced by ecological factors? The authors familiarize the reader with cutting-edge ideas on the ecology and evolution of group-living animals, and detail fascinating case studies demonstrating them in action.

Download or read book The Evolutionary Biology of the Threespine Stickleback written by Michael A. Bell and published by Oxford University Press on Demand. This book was released on 1994 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: The threespine stickleback is a small fish of temperate coastal and fresh waters that exhibits extraordinary phenotypic diversity. Benefiting from its amenability to observation in the field and manipulation in the laboratory, Niko Tinbergen pioneered the threespine stickleback's use in behavioral studies and established it as a model system in ethology. This up-to-date volume incorporates reviews from active researchers who use studies of the fish to address a broad variety of evolutionary issues, including optimal foraging, armor variation, speciation, and the endocrine basis for correlated behavioral characters. The work demonstrates the value of viewing the biology of a single organism simultaneously from multiple perspectives. Students and researchers in ecology, evolution, animal behavior, and vertebrate zoology will find much of interest in this useful book.

Download or read book The Fishes of Tennessee written by David A. Etnier and published by . This book was released on 1993 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: The waters of Tennessee are home to about three hundred species of fishes, the most diverse collection of freshwater fauna of any state in the country. This readable and authoritative book, first published in 1993, examines that diversity within the state's complex natural history. It not only synthesizes a wealth of scientific information but also presents a tremendous amount of original research. Species accounts provide information on the classification, identification, biology, distribution, taxonomy, and current status of Tennessee's fishes -- many of which are endangered. Taxonomic keys provide readers with guides for distinguishing species. Extensive use is made of high-quality photographs, range maps, and drawings. For this second printing, the authors have provided corrections and updated information. This data includes seven new species accounts and new distributional information.

Download or read book Animals and Temperature written by Ian A. Johnston and published by Cambridge University Press. This book was released on 2008-02-14 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organisms are continually challenged to regulate and maintain functional capacities as their thermal environment changes. Adjustment to temperature change is evident both phenotypically in individual organisms and genotypically in the evolution of species. This volume addresses thermal adaptation by bringing together many of the leading researchers in thermal biology, with backgrounds spanning the disciplines of molecular biology, cell biology, physiology, zoology, ecology and evolutionary biology. The responses of many species to temperature are discussed in depth, through the molecular, cellular, organismal, population, and ecosystem levels. This text stands as an important contribution to the study of temperature adaptation.

Download or read book Ireland s Rivers written by Mary Kelly-Quinn and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a fascinating study of the varied nature of Irish river ecosystems--their beauty, significance, and the natural and human factors that make each one distinct. Ireland's Atlantic climate, alongside its largely agricultural economy and relatively small population, make the nature of Irish rivers vastly different from those on the European continent. With that in mind, there is significant interest in implementing measures to protect the dwindling number of near-pristine rivers in Ireland. This beautifully illustrated book provides a wonderful overview of Irish rivers and the risks that conservationists face in preserving their unique natural beauty.
