Book Description
Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers has attracted increased attention, particularly the areas of hydrology and geomorphology, and the inter-relationships between physical and biological factors have become better understood. And as is true for every area of ecology during the closing years of the twentieth century it has become apparent that the study of streams and rivers cannot be carried out by excluding the role of human activities, nor can we ignore the urgency of the need for conservation. These developments are brought together in Stream Ecology: Structure and function of running waters, designed to serve as a text for advanced undergraduate and graduate students, and as a reference book for specialists in stream ecology and related fields.

Book Description
This extensively revised, restructured, and updated edition continues to present an engaging and comprehensive introduction to the subject, exploring the world’s landforms from a broad systems perspective. It covers the basics of Earth surface forms and processes, while reflecting on the latest developments in the field. Fundamentals of Geomorphology begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss: structure: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; and landscape evolution, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change. This third edition has been fully updated to include a clearer initial explanation of the nature of geomorphology, of land surface process and form, and of land-surface change over different timescales. The text has been restructured to incorporate information on geomorphic materials and processes at more suitable points in the book. Finally, historical geomorphology has been integrated throughout the text to reflect the importance of history in all aspects of geomorphology. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries, and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, all in colour.

Book Description
The darters are a fascinating group of colorful and diminutive freshwater fish whose beauty rivals that of the tropical reef fishes. Native only to North America, the darters occur widely, especially in the United States, but are little known to the general public, largely because of their small size—few exceed six inches and some measure a mere one inch at maturity. This book is the first comprehensive guide to the darters, covering all named and several undescribed forms—140 species in all. Each species account includes a synoptic description to aid in separation of similar species and subspecies, a range map, and discussion of the species' distribution, natural heritage, abundance, and scientific name. An illustrated key and glossary will further assist scientists, students, fishermen, and aquarium specialists in identifying darter species. Central to this volume is the series of 144 handsome color photographs illustrating nearly all known darter species and several subspecies. Most of the specimens shown were caught by the authors at sites throughout the United States, Canada, and Mexico, and photographed by them on site using a recently developed technique that captures the full brilliance of the living fish. Because of their importance as indicators of environmental quality, the darters are receiving increasing attention today from scientists and naturalists. Public interest was focused recently on the plight of the snail darter, but many other darter species are either threatened or endangered, and others face an uncertain future as human activities continue to degrade our waterways. All those with an interest in preserving the natural heritage of our rivers and streams will find this comprehensive guide to the darters an invaluable tool.
