We all rely on a familiar set of indicators - interest rates, unemployment, inflation, the Dow Jones index, and GDP, for example - to gauge the performance of national economies. No such measures are currently available to describe the environment. This book lays out a blueprint for periodic reporting on the condition and use of ecosystems in the United States. Developed by experts from businesses, environmental organizations, universities, and federal, state, and local government agencies, it is designed to provide policymakers and the general public with a succinct and comprehensive - yet scientifically sound and non-partisan - view of 'how we are doing'. This book should prove invaluable for decision makers in natural resource management and environmental policy in government and environmental organizations, businesses, and trade associations; academics with a research or teaching interest in environmental issues; and the general public interested in the continued well-being of American ecosystems.

The Amazon forest is one of the world's most complex, unknown and threatened ecosystems that holds a considerable part of the Earths biodiversity. This ecosystem needs greater scientific attention so that we can better understand the features of its fauna and conserve species before they become extinct. Thus, this book addresses issues about resources within Earths largest rainforest. In addition, the knowledge of the molluscs in the Amazon region is extremely scarce, and in most cases only information concerning their spatial distribution is available. Specifically, for the gastropods of the Pomacea genus, which were introduced in every continent and became known as pests, scientific knowledge in native areas is very important to understand. Research may help to control these organisms and the many areas they tend to invade. Specialists and scientists that work with apple snails in the Amazon and around the world can access new information about the species that inhabit this region with unprecedented advances in various scientific aspects such as diversity and occurrence, anatomy aspects of Pomacea in Peru, and phylogeny of this group in the Amazon region. Information about the biological aspects such as imposex development, effects of the dry season duration in the gastropod growth, aquaculture technical to human food production, and reproduction (including oviposition, fecundity, substrate selection, ultrastructural view of spermatozoa and egg predation). All of this is synthesised to bring the reader an informative compilation of data and research focusing on apple snails of the Amazon.

From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.
