Book Description
Indexes the world's zoological and animal science literature, covering all research from biochemistry to veterinary medicine. The database provides a collection of references from over 4,500 international serial publications, plus books, meetings, reviews and other no- serial literature from over 100 countries. It is the oldest continuing database of animal biology, indexing literature published from 1864 to the present. Zoological Record has long been recognized as the "unofficial register" for taxonomy and systematics, but other topics in animal biology are also covered.

Book Description
Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)

Book Description
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.

Book Description
Dennis Dalton's classic account of Gandhi's political and intellectual development focuses on the leader's two signal triumphs: the civil disobedience movement (or salt satyagraha) of 1930 and the Calcutta fast of 1947. Dalton clearly demonstrates how Gandhi's lifelong career in national politics gave him the opportunity to develop and refine his ideals. He then concludes with a comparison of Gandhi's methods and the strategies of Martin Luther King Jr. and Malcolm X, drawing a fascinating juxtaposition that enriches the biography of all three figures and asserts Gandhi's relevance to the study of race and political leadership in America. Dalton situates Gandhi within the "clash of civilizations" debate, identifying the implications of his work on continuing nonviolent protests. He also extensively reviews Gandhian studies and adds a detailed chronology of events in Gandhi's life.
