Available in PDF, EPUB and Kindle. Book excerpt: The Speckled Dace (Rhinichthys osculus) is a small freshwater minnow. Recent field studies have confirmed a large and apparently robust population of Speckled Dace throughout its Canadian range, far in excess of previous estimates made prior to being listed as Endangered in Schedule 1 of the Species at Risk Act (SARA). This document includes an executive summary, recovery feasibility summary, measuring progress, and statement on action plans.--Includes text from document.

Available in PDF, EPUB and Kindle. Book excerpt: Written as a stand-alone textbook for students and a useful reference for professionals in government and private agencies, academic institutions, and consultants, Ecology and Conservation of Fishes provides broad, comprehensive, and systematic coverage of all aquatic systems from the mountains to the oceans. The book begins with overview discussions on the ecology, evolution, and diversity of fishes. It moves on to address freshwater, estuarine, and marine ecosystems and identifies factors that affect the distribution and abundance of fishes. It then examines the adaptations of fishes as a response to constraints posed in ecosystems. The book concludes with four chapters on applied ecology to discuss the critical issues of management, conservation, biodiversity crises, and climate change. Major marine fisheries have collapsed, and there are worldwide declines in freshwater fish populations. Fishery scientists and managers must become more effective at understanding and dealing with resource issues. If not, fish species, communities, and entire ecosystems will continue to decline as habitats change and species are lost. Ecology and Conservation of Fishes has taken a historical and functional approach to explain how we got where we are, providing old and new with a better foundation as ecologists and conservationists, and most importantly, it awakens senses of purpose and need. Past management practices are reviewed, present programs considered, and the need for incorporating principles of applied ecology in future practices is emphasized.

Download or read book Battle Against Extinction written by W. L. Minckley and published by . This book was released on 1991-12 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1962 the Green River was poisoned and its native fishes killed so that the new Flaming Gorge Reservoir could be stocked with non-native game fishes for sportsmen. This incident was representative of water management in the West, where dams and other projects have been built to serve human needs without consideration for the effects of water diversion or depletion on the ecosystem. Indeed, it took a Supreme Court decision in 1976 to save Devils Hole pupfish from habitat destruction at the hands of developers. Nearly a third of the native fish fauna of North America lives in the arid West; this book traces their decline toward extinction as a result of human interference and the threat to their genetic diversity posed by decreases in their populations. What can be done to slow or end this tragedy? As the most comprehensive treatment ever attempted on the subject, Battle Against Extinction shows how conservation efforts have been or can be used to reverse these trends. In covering fishes in arid lands west of the Mississippi Valley, the contributors provide a species-by-species appraisal of their status and potential for recovery, bringing together in one volume nearly all of the scattered literature on western fishes to produce a monumental work in conservation biology. They also ponder ethical considerations related to the issue, ask why conservation efforts have not proceeded at a proper pace, and suggest how native fish protection relates to other aspects of biodiversity planetwide. Their insights will allow scientific and public agencies to evaluate future management of these animal populations and will offer additional guidance for those active in water rights and conservation biology. First published in 1991, Battle Against Extinction is now back in print and available as an open-access e-book thanks to the Desert Fishes Council.
Download or read book The Los Angeles River written by Blake Gumprecht and published by JHU Press. This book was released on 2001-04-30 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the J. B. Jackson Prize from the Association of American Geographers Three centuries ago, the Los Angeles River meandered through marshes and forests of willow and sycamore. Trout spawned in its waters and grizzly bears roamed its shores. The bountiful environment the river helped create supported one of the largest concentrations of Indians in North America. Today, the river is made almost entirely of concrete. Chain-link fence and barbed wire line its course. Shopping carts and trash litter its channel. Little water flows in the river most of the year, and nearly all that does is treated sewage and oily street runoff. On much of its course, the river looks more like a deserted freeway than a river. The river's contemporary image belies its former character and its importance to the development of Southern California. Los Angeles would not exist were it not for the river, and the river was crucial to its growth. Recognizing its past and future potential, a potent movement has developed to revitalize its course. The Los Angeles River offers the first comprehensive account of a river that helped give birth to one of the world's great cities, significantly shaped its history, and promises to play a key role in its future.

Book excerpt: The 1980 eruption of Mount St. Helens caused tragic loss of life and property, but also created a unique opportunity to study a huge disturbance of natural systems and their subsequent responses. This book synthesizes 25 years of ecological research into of volcanic activity, and shows what actually happens when a volcano erupts, what the immediate and long-term dangers are, and how life reasserts itself in the environment.
Download or read book Lampreys Biology Conservation and Control written by Margaret F. Docker and published by Springer. This book was released on 2014-11-24 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides the most comprehensive review of lamprey biology since Hardisty and Potter’s five-volume “The Biology of Lampreys” published more than 30 years ago. Published in two volumes, it includes contributions from international lamprey experts, reviewing and providing new insights into the evolution, general biology, and management of lampreys worldwide. This first volume offers up-to-date chapters on the systematics, general biology, conservation status, and conservation needs of lampreys. It will serve as an important reference for researchers working on any aspect of lamprey biology and fishery managers whose mandate is to control or conserve lamprey populations.
