Fouling occurs when marine microbes, plants, and animals, and/or their spores and larvae attach and grow on the hull of a boat or ship. If they survive the trip to a distant harbor, they may spawn, release spores, or be removed and discarded there. If they succeed in the new area, they may create problems.
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 Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)
The ongoing growth of human populations within US coastal regions continues to increase habitat loss, eutrophication, organic loading, overfishing, and other anthropogenic stressors in estuarine waters. The National Estuarine Research Reserve System (NERRS) is a federally funded initiative that addresses these critical estuarine problems an
How does nature work in our human-created city, suburb, and exurb/peri-urb? Indeed how is ecology - including its urban water, soil, air, plant, and animal foundations - spatially entwined with this great human enterprise? And how can we improve urban areas for both nature and people? Urban Ecology: Science of Cities explores the entire urban area: from streets, lawns, and parks to riversides, sewer systems, and industrial sites. The book presents models, patterns, and examples from hundreds of cities worldwide. Numerous illustrations enrich the presentation. Cities are analyzed, not as ecologically bad or good, but as places with concentrated rather than dispersed people. Urban ecology principles, traditionally adapted from natural-area ecology, now increasingly emerge from the distinctive features of cities. Spatial patterns and flows, linking organisms, built structures, and the physical environment highlight a treasure chest of useful principles. This pioneering interdisciplinary book opens up frontiers of insight, as a valuable source and text for undergraduates, graduates, researchers, professionals, and others with a thirst for solutions to growing urban problems.
"Human Impacts on Salt Marshes provides an excellent global synthesis of an important, underappreciated environmental problem and suggests solutions to the diverse threats affecting salt marshes."—Peter B. Moyle, University of California, Davis
