Science for Ecosystem-based Management: Narragansett Bay in the 21st Century addresses the broad problem of coastal nutrient pollution. In the U.S., approximately two thirds of the coastal rivers and bays are moderately to severely degraded from nutrient pollution. However, debates continue about how large a problem nutrient pollution is and what actions to take, and since effective management requires decisions at a local scale, an in-depth case study can provide valuable guidance.

Narragansett Bay is one of the best-studied estuaries in the world. Rhode Island has been developing...

Caddisflies constitute the insect order Trichoptera in which some 10,000 species are known in the world, including about 1400 in North America. Fossil evidence shows that caddisflies originated in the Triassic period, 200-250 million years ago. They are important links in the movement of energy and nutrients through freshwater ecosystems due largely to the extraordinary diversification in their larval architecture, which includes portable and stationary shelters, silken filter nets, and osmotically semipermeable cocoons. Glenn Wiggins's Caddisflies is the foremost comprehensive...

Even a cursory perusal of any analytical journal will demonstrate the increasing important of trace and ultra-trace analysis. And as instrumentation continues to develop, the definition of the term "trace element" will undoubtedly continue to change. Covering the composition and underlying properties of freshwater and marine systems, Analytical Measurements in Aquatic Environments provides the basis for understanding both. It discusses all aspects of analytical protocols from the handling of representative samples to the metrological evaluation of specific steps and whole...

Meiobenthology is the science of the tiny animals that live in huge numbers in all aquatic sediments. This fully revised and enlarged second edition emphasizes new discoveries and developments in this field. Major progress has been made in three general areas: - Systematics, diversity and distribution, - Ecology, food webs, and energy flow, - Environmental aspects, including studies of anthropogenic impacts.

The meiobenthos of polar and tropical regions, deep-sea bottoms and hydrothermal vents are now studied in more detail. The high number of species found to...

The culture of the Middle Ages was as complex, if not as various, as our own, as the essays in this volume ably demonstrate. The essays cover a wide range of tipics, from church sculpture as "advertisement" to tricks and illusions as "homeeconomics."

Among the hundreds of thousands of species of beetles, there is one family, containing some 4,300 species, that stands out as one of the most diverse and important groups of aquatic predatory insects. This is the Dytiscidae, whose species are commonly known as diving beetles. No comprehensive treatment of this group has been compiled in over 130 years, a period during which a great many changes in classification and a near quadrupling of known species has occurred.

In Diving Beetles of the World, Kelly B. Miller and Johannes Bergsten provide the only full treatments of all 188...

The Mekong Region has come to represent many of the important water governance challenges faced more broadly by the mainland Southeast Asian region. This book focuses on the complex nature of water rights and social justice in the Mekong region. The chapters delve into the diverse social, political and cultural dynamics that shape the various realities and scales of water governance in the region, in an effort to bring to the forefront some of the local nuances required in the formulation of a larger vision of justice in water governance. It is hoped that this contextualized analysis will...
