The 135 comprehensive species accounts summarize the present knowledge. Each begins with the etymology of a species' common and scientific names, followed by the description, identifying characteristics, geographic range, biology, reproduction, location of nurseries, growth and longevity, and...

Managing disease in free-ranging wild mammals presents serious challenges. This book provides an authoritative contemporary review of the major issues and challenges in the management of disease in wild mammals.

Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North...

Homeostasis and Toxicology of Non-Essential Metals synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years. These elements are no longer viewed by fish physiologists as "heavy metals" that kill fish by suffocation, but rather as interesting moieties that enter and leave fish by specific pathways, which are subject to physiological regulation. The metals featured in this volume are those about which there has been most public and scientific concern, and therefore are those most widely studied by fish...

Most people think of pythons as giant snakes in distant tropical jungles, but Burmese pythons, which can reach lengths of over twenty feet and weigh over two hundred pounds, are now thriving in southern Florida.

These natives of Asia are commonly kept as pets and presumably escaped or were released in the Everglades. Pythons are now common in this region; widespread throughout hundreds of square miles, they are breeding and appear to be expanding their range. Pythons are voracious predators that feed on a variety of native wildlife including wading birds, bobcats, white-tailed deer, and...

In light of mounting fishing pressures, increased aquaculture production and a growing concern for fish well-being, improved knowledge on the swimming physiology of fish and its application to fisheries science and aquaculture is needed. This book presents recent investigations into some of the most extreme examples of swimming migrations in salmons, eels and tunas, integrating knowledge on their performance in the laboratory with that in their natural environment. For the first time, the application of swimming in aquaculture is explored by assessing the potential impacts and beneficial...

While there has been a long history of salmon hatchery operations throughout the North Pacific, only recently have we begun to investigate how hatchery salmon interact with their wild counterparts. This volume represents our latest understanding of the scale and magnitude of effects of hatcheries on wild salmon populations, and begins to lay the groundwork for precautionary fisheries management to ensure that wild salmon are conserved. Reprinted from Environmental Biology of Fishes volume 94 issue 1

Research on hatchery and wild salmonid interactions is increasing...

New Mexico is home to 165 species and subspecies of snakes, lizards, turtles, frogs, toads, and salamanders. Some are ubiquitous and others are localized. If you want basic and reliable information on the lizard in your backyard or the snake you encountered on a hike in the mountains, this handy field guide is invaluable. Both complete and concise, it includes species accounts, maps, photographs, and black-and-white drawings to help you identify the species you have encountered. In addition to basic taxonomy and a glossary, the authors have included suggestions on field protocol and...

The California Current System is one of the best studied ocean regions of the world, and the level of oceanographic information available is perhaps only surpassed by the northeast and northwest Atlantic.The current literature (later than 1993) offers no comprehensive, integrated review of the regional fisheries oceanography of the California Current System.

This volume summarizes information of more than 60-year California Cooperative Oceanic Fisheries Investigation (CalCOFI).While providing a large bibliography, the intent was to extract themes relevant to current research rather...
