Book Description
Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 55. Nutrient and contaminant inputs to estuaries and coastal seas, the exploitation of living resources, translocation of nonindigenous species, and habitat loss or modification are among the most significant and sustained anthropogenic alterations of coastal ecosystems. Although the chapters that follow touch on all of these issues, the causes and consequences of nutrient enrichment are emphasized. Nutrient enrichment of estuaries and coastal seas has increased dramatically in recent decades, largely as a consequence of the combustion of fossil fuels and land-use patterns in coastal watersheds related to increases in population density and agriculture. How these changes and the compounding effects of meteorological events and local?]regional expressions of global climate change will play out in terms of ecosystem dynamics are important questions that will drive research and monitoring in the coastal zone for decades to come.

Book Description
The Gulf of California is one of the most beautiful places in the world, but it is also important to earth and marine scientists who work far beyond the area. In text and an accompanying CD-ROM with stunning satellite images, this atlas captures the dynamics of natural cycles in the fertility of the Gulf of California that have been in near-continuous operation for more than five million years. The book is designed to answer key questions that link the health of coastal ecosystems with the regionÕs evolutionary history: What was the richness of ÒfossilÓ ecosystems in the Gulf of California? How has it changed over time? Which ecosystems are most amenable to conservation? With an emphasis on the intricate workings of the Gulf, a team of scientists led by Markes E. Johnson and Jorge Ledesma-V‡zquez explores how marine invertebrates such as corals and bivalves, as well as certain algae, contribute to the operation of a vast Òorganic engineÓ that acts as a significant carbon trap. The Atlas reveals that the role of these organisms in the ecology of the Gulf was greatly underestimated in the past. The organisms that live in these environments (or provide the sediments for beaches and dunes) are mass producers of calcium carbonate. Until now, no book has considered the centrality of calcium carbonate production as it functions today across multiple ecosystems and how it has evolved over time. An important work of scholarship that also evokes the regionÕs natural splendor, the Atlas will be of interest to a wide range of scientists, including geologists, paleontologists, marine biologists, ecologists, and conservation biologists.

Book Description
Explores how two coastal ecosystems are responding to the pressures of human expansion The Northern Adriatic Sea, a continental shelf ecosystem in the Northeast Mediterranean Sea, and the Chesapeake Bay, a major estuary of the mid-Atlantic coast of the United States, are semi-enclosed, river-dominated ecosystems with urbanized watersheds that support extensive industrial agriculture. Coastal Ecosystems in Transition: A Comparative Analysis of the Northern Adriatic and Chesapeake Bay presents an update of a study published two decades ago. Revisiting these two ecosystems provides an opportunity to assess changing anthropogenic pressures in the context of global climate change. The new insights can be used to inform ecosystem-based approaches to sustainable development of coastal environments. Volume highlights include: Effects of nutrient enrichment and climate-driven changes on critical coastal habitats Patterns of stratification and circulation Food web dynamics from phytoplankton to fish Nutrient cycling, water quality, and harmful algal events Causes and consequences of interannual variability The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Read a review of this book in Marine Ecology review of this book

This volume reflects the present state of the study of the Mediterranean as carried out by the Italian scientific community. The multidisciplinary character of the papers creates different "transversal" reading and clustering possibilities that the informed reader is free to design and undertake autonomously.

Book Description
Coastal wetlands are under a great deal of pressure from the dual forces of rising sea level and the intervention of human populations both along the estuary and in the river catchment. Direct impacts include the destruction or degradation of wetlands from land reclamation and infrastructures. Indirect impacts derive from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. As sea level rises, coastal wetlands in most areas of the world migrate landward to occupy former uplands. The competition of these lands from human development is intensifying, making the landward migration impossible in many cases. This book provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide, and suggestions for their management. In this book a CD is included containing color figures of wetlands and estuaries in different parts of the world. - Includes a CD containing color figures of wetlands and estuaries in different parts of the world.

Book Description
R. David Simpson Norman L. Christensen, Jr. Human Activity and Ecosystem Function: Reconciling Economics and Ecology Recognizing the need to improve social decision making on tradeoffs between economic growth and ecological health, the Renewable Natural Resources Foundation convened a workshop in October 1995 on "Human Activity and Ecosystem Function: Reconciling Economics and Ecology. " While the subtitle perhaps reflected unrealistic expectations, the presentations and discus sions at the workshop were a preliminary step toward that rec onciliation: bringing together ecologists, economists, other nat ural and social scientists, and policy makers to layout the issues, articulate their needs and perspectives, and identify common ground for further work. This volume contains the pa pers presented and reports generated from the workshop. We emphasize ecology and economics in this discussion. We could argue that organizing our inquiry around these diSCiplines is only natural. Ecology is the study of behavior of organisms within complex systems composed of a myriad of other organ isms and their physical environments. Increasingly, this disci pline has focused on how interactions among biological and physical components influence the overall functioning of ecosys tems. These components are increasingly being determined by viii Ecosystem Function and Human Activities human activities. Economics is the study of how we decide which of our needs and wants we choose to satisfy given our limited re sources.

Book Description
In order to answer important questions about ecosystems and biodiversity, scientists can look to the past geological recordâ€"which includes fossils, sediment and ice cores, and tree rings. Because of recent advances in earth scientists' ability to analyze biological and environmental information from geological data, the National Science Foundation and the U.S. Geological Survey asked a National Research Council (NRC) committee to assess the scientific opportunities provided by the geologic record and recommend how scientists can take advantage of these opportunities for the nation's benefit. The committee identified three initiatives for future research to be developed over the next decade: (1) use the geological record as a "natural laboratory" to explore changes in living things under a range of past conditions, (2) use the record to better predict the response of biological systems to climate change, and (3) use geologic information to evaluate the effects of human and non-human factors on ecosystems. The committee also offered suggestions for improving the field through better training, improved databases, and additional funding.
