Freshwater life – the first illustrated field guide of its kind for the wider southern African region – describes a vast range of plant and animal groups in a single volume. A ground-breaking concept that encompasses diverse groups from the large and conspicuous vertebrates to the diverse microscopic taxa, the book facilitates identification and describes the ecology of more than 1,000 freshwater organisms. Species have been selected on the basis of how likely they are to be encountered, and each account is accompanied by photographs and a distribution map. A comprehensive introduction details the ecology and signifi cance of freshwater systems. This indispensible, easy-to-use guide will prove invaluable to outdoor enthusiasts, students and conservationists.

Plant and animal life of North American ponds and streams, with special emphasis on the adaptions which make locomotion, respiration, food-getting, and reproduction possible beneath the surface of the water.
At least 162 species of fish are known to live or spawn in the freshwaters of the Northeast, representing twenty-eight families and sixteen orders. This diversity springs from an enormous variety of freshwater habitats, including some of the largest lakes in the world; vast and complex river systems; deep, clear lakes in Maine and the Adirondack Mountains; and myriad small lakes, bogs, marshes, and streams that dot the northeast. In the most comprehensive book of its kind, Robert G. Werner offers a thorough survey and analysis, in accessible field guide form, of the region's abundant freshwater fishes. Werner's discussion of the geological history of the region serves as a critical background for understanding not only the fascinating habitats of fishes but also the extensive watersheds and drainages of the region. A reference list provides up-to-date sources, and the species descriptions contain the latest relevant data and research on specific fish. In addition, vivid color plates and extensive line drawings illustrate fish morphology and the distinctive natural colors of numerous species. As a standard resource, this guide will attract a wide audience. This book will be useful to biologists, ecologists, and zoologists and will have an indispensable appeal among anglers, environmentalists, and fisheries professionals.
A beautifully illustrated guide to the diverse and numerous freshwater fish species in Virginia. In Field Guide to Freshwater Fishes of Virginia, the foremost experts on Commonwealth fishes bring their decades of field experience to readers, offering a complete reference to the fishes of the entire state of Virginia. Gathering information that until now could only be found scattered across numerous reference works and online databases, this book provides everything you need to know to identify fish families and species in the Virginia region. Covering how to collect, handle, observe, conserve, and protect these unique fishes, the book's key features include • more than 175 vibrant, full-color illustrations, set side by side with descriptions of each fish • helpful line drawings that depict the most reliable diagnostic characteristics for field identifications (e.g., snout shape, pigment patterns, mouth morphology) • descriptions of Virginia's freshwater habitats • examples of incredible fish spawning and feeding behavior • tips on observing fish in the wild and in captivity • a chapter on the taxonomy of family and common names of the fish species most common throughout Virginia • up-to-date fish distribution maps • a complete glossary of terms Providing a fascinating foray into the wonders of the Commonwealth's swimmers, Field Guide to Freshwater Fishes of Virginia will appeal to scientists, naturalists, teachers, native fish aquarists, students, anglers, and fish collectors.
The Amazon and Orinoco basins in northern South America are home to the highest concentration of freshwater fish species on earth, with more than 3,000 species allotted to 564 genera. Amazonian fishes include piranhas, electric eels, freshwater stingrays, a myriad of beautiful small-bodied tetras and catfishes, and the largest scaled freshwater fish in the world, the pirarucu. Field Guide to the Fishes of the Amazon, Orinoco, and Guianas provides descriptions and identification keys for all the known genera of fishes that inhabit Greater Amazonia, a vast and still mostly remote region of tropical rainforests, seasonally flooded savannas, and meandering lowland rivers. The guide’s contributors include more than fifty expert scientists. They summarize the current state of knowledge on the taxonomy, species richness, and ecology of these fish groups, and provide references to relevant literature for species-level identifications. This richly illustrated guide contains 700 detailed drawings, 190 color photos, and 500 distribution maps, which cover all genera. An extensive and illustrated glossary helps readers with the identification keys. The first complete overview of the fish diversity in the Amazon, Orinoco, and Guianas, this comprehensive guide is essential for anyone interested in the freshwater life inhabiting this part of the world. First complete overview of the fish diversity in the Amazon and Orinoco basins Contributors include more than fifty experts Identification keys and distribution maps for all genera 190 stunning color photos 700 detailed line drawings Extensive and illustrated glossary
The North American freshwater fish fauna is the most diverse and thoroughly researched temperate fish fauna in the world. Ecology of North American Freshwater Fishes is the only textbook to provide advanced undergraduate and graduate students and researchers with an up-to-date and integrated view of the ecological and evolutionary concepts, principles, and processes involved in the formation and maintenance of this fauna. Ecology of North American Freshwater Fishes provides readers with a broad understanding of why specific species and assemblages occur in particular places. Additionally, the text explores how individuals and species interact with each other and with their environments, how such interactions have been altered by anthropogenic impacts, and the relative success of efforts to restore damaged ecosystems. This book is designed for use in courses related to aquatic and fish ecology, fish biology, ichthyology, and related advanced ecology and conservation courses, and is divided into five sections for ease of use. Chapter summaries, supplemental reading lists, online sources, extensive figures, and color photography are included to guide readers through the material and facilitate student learning. Part 1: Faunal origins, evolution, and diversity Presents a broad pictureÑboth spatially and temporallyÑof the derivation of the fauna, including global and regional geological and climatological processes and their effects on North American fishes. Part 2: Formation, maintenance, and persistence of local populations and assemblages Focuses on how local fish populations and assemblages are formed and how they persist, or not, through time. Part 3: Form and function Deals with the relationship of body form and life history patterns as they are related to ecological functions. Part 4: Interactions among individuals and species Discusses the numerous interactions among individuals and species through communication, competition, predation, mutualism, and facilitation. Part 5: Issues in conservation Focuses on several primary conservation issues such as flow alterations and the increasing biotic homogenization of faunas.
Provides a stark examination of the current state of the Earth's freshwater ecosystems. This title tells us why Earth's freshwater supplies and systems are in peril.
