Download or read book Freshwater Fish Distribution written by Tim M. Berra and published by University of Chicago Press. This book was released on 2008-09-15 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2017-08-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Download or read book Lampreys Biology Conservation and Control written by Margaret F. Docker and published by Springer. This book was released on 2019-06-03 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, published in two volumes, provides the most comprehensive review of lamprey biology since Hardisty and Potter’s “The Biology of Lampreys” published more than 30 years ago. This second volume offers a synthesis of topics related to the lamprey gonad (e.g., lamprey sex ratios, sex determination and sex differentiation, sexual maturation, and sex steroids), the artifical propagation of lampreys, post-metamorphic feeding and the evolution of alternative feeding and migratory types, the history and status of sea lamprey control in the Laurentian Great Lakes and Lake Champlain, and an overview of contributions of lamprey developmental studies for understanding vertebrate evolution.
Download or read book In Our Own Hands written by Deborah B. Jensen and published by . This book was released on 1993 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Biodiversity." As argument over environmental and conservation policy grows more heated in California and throughout the nation, the term has become a buzzword. But what does biodiversity really mean? What really threatens it? Why should we care? In Our Own Hands offers a readable, scientifically sound view of California's biological diversity and what must be done to preserve it. The book will be an invaluable resource for environmental and natural resource specialists, educators, and general readers. Local and global forces threaten California's wetlands, dunes, oak woodlands, and riparian forest habitats--all declining habitats in a rapidly urbanizing, culturally heterogeneous, and politically turbulent state. Always a bellwether, California will be a model for the rest of the United States in its scientific and political solutions to conservation problems. This book proposes the first steps toward a unified national conservation policy for the twenty-first century. "Biodiversity."

Download or read book Fish Conservation written by Gene S. Helfman and published by Island Press. This book was released on 2007-07-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish Conservation offers, for the first time in a single volume, a readable reference with a global approach to marine and freshwater fish diversity and fishery resource issues. Gene Helfman brings together available knowledge on the decline and restoration of freshwater and marine fishes, providing ecologically sound answers to biodiversity declines as well as to fishery management problems at the subsistence, recreational, and commercial levels. Written in an engaging and accessible style, the book: considers the value of preserving aquatic biodiversity offers an overview of imperiled fishes on a taxonomic and geographic basis presents a synthesis of common characteristics of imperiled fishes and their habitats details anthropogenic causes of decline examines human exploitation issues addresses ethical questions surrounding exploitation of fishes The final chapter integrates topics and evaluates prospects for arresting declines, emphasizing the application of evolutionary and ecological principles in light of projected trends. Throughout, Helfman provides examples, explores case studies, and synthesizes available information from a broad taxonomic, habitat, and geographic range. Fish Conservation summarizes the current state of knowledge about the degradation and restoration of diversity among fishes and the productivity of fishery resources, pointing out areas where progress has been made and where more needs to be done. Solutions focus on the application of ecological knowledge to solving practical problems, recognizing that effective biodiversity conservation depends on meeting human needs through management that focuses on long term sustainability and an ecosystem perspective.

Download or read book Coastal Watershed Management written by A. Fares and published by WIT Press. This book was released on 2008-05-23 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal watersheds differ from others by their unique features, including proximity to the ocean, weather and rainfall patterns, subsurface features, and land covers. Land use changes and competing needs for valuable water and land resources are especially more distinctive to such watersheds. This book covers recent research relevant to coastal watersheds. It addresses the impact of a stream’s chemical, biological, and sediment pollutants on the quality of the receiving waters, such as estuaries, bays, and near-shore waters. The contents of the book can be divided into three sections; a) overview of hydrological modelling, b) water quality assessment, and c) watershed management. This book differs from other hydrology books by dealing with coastal watersheds which are characterized by their unique features: including weather and rainfall patterns, subsurface characteristics, and land use and cover. In addition to academia, the book should be of interest to organizations concerned with watershed management, such as local and federal governments and environmental groups. Overall, the book is expected to satisfy a great need toward understanding and managing critical areas in many parts of the world.
