The definitive reference in its field, Ecological Risk Assessment, Second Edition details the latest advances in science and practice. In the fourteen years since the publication of the best-selling first edition, ecological risk assessment (ERA) has moved from the margins into the spotlight. It is now commonly applied to the regulation of chemicals, the remediation of contaminated sites, the monitoring of importation of exotic organisms, the management of watersheds, and other environmental management issues.

Delineating the processes for performing an ERA, the book begins by defining the field, then goes on to describe its relationship to other environmental assessment practices and its organizational framework. The book also includes a chapter on ecological epidemiology, which has previously been treated as a type of ERA, but is now recognized as a distinct practice in itself. It explores important concepts in the ERA process including probability, uncertainty, scale, mode of action and multiple causes.

Reflecting changes in the field, the book's scope has been broadened to include discussions of the application of ERA to agents other than chemical contaminants. The multitude of illustrative figures provides a flavor for the diverse practice of ERA. The author has re-organized the material, presenting a unitary process of ERA that is applicable to various problems, scales, and mandates. He keeps the emphasis squarely on providing clear, scientifically sound, and unbiased technical advice on the risks from chemicals and chemical mixtures.

In autumn, a strong wind blows flower seeds high in the air and carries them far across the land. One by one, many of the seeds are lost -- burned by the sun, fallen into the ocean, eaten by a bird. But some survive the long winter and, come spring, sprout into plants, facing new dangers -- trampled by playing children, picked as a gift for a friend. Soon only the tiniest seed remains, growing into a giant flower and, when autumn returns, sending its own seeds into the wind to start the process over again.

If you look carefully, you can find them and be amazed! These secret pools form every year when low places on the forest floor fill up with rain and melted snow. They soon become home to hatching wood frogs, spotted salamanders, and fairy shrimp.

The Secret Pool introduces young readers to the wonders right underfoot as the voice of a vernal pool shares its secrets through the seasons, and sidebars provide fun facts on its inhabitants and the crucial role these small, often overlooked wetlands play in maintaining a healthy environment. This edition includes new backmatter features about wetland habitats and animals for classroom use and reader interest.
