Few places in the world can claim such a diversity of species as the Gulf of California (Sea of Cortez), with its 6,000 recorded animal species estimated to be half the number actually living in its waters. So rich are the Gulf's water that over a half-million tons of seafood are taken from them annually—and this figure does not count the wasted by-catch, which would triple or quadruple that tonnage. This timely book provides a benchmark for understanding the Gulf's extraordinary diversity, how it is threatened, and in what ways it is—or should be—protected. In spite of its dazzling richness, most of the Gulf's coastline now harbors but a pale shadow of the diversity that existed just a half-century ago. Recommendations based on sound, careful science must guide Mexico in moving forward to protect the Gulf of California. This edited volume contains contributions by twenty-four Gulf of California experts, from both sides of the U.S.-Mexico border. From the origins of the Gulf to its physical and chemical characteristics, from urgently needed conservation alternatives for fisheries and the entire Gulf ecosystem to information about its invertebrates, fishes, cetaceans, and sea turtles, this thought-provoking book provides new insights and clear paths to achieve sustainable use solidly based on robust science. The interdisciplinary, international cooperation involved in creating this much-needed collection provides a model for achieving success in answering critically important questions about a precious but rapidly disappearing ecological treasure.

The many economic factors affecting sustainability of the Gulf of Mexico region are perhaps as important as the waves on its shores and its abundant marine life. This second volume in Gulf of Mexico Origin, Waters, and Biota (a multivolumed work edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle) assesses the Gulf of Mexico as a single economic region. The book provides information and baseline data useful for assessing the goals of economic and environmental sustainability in the Gulf. In five chapters, economists, political scientists, and ecologists from Florida, California, Louisiana, Texas, Maine, and Mexico cover topics such as: the idea of the Gulf as a transnational community; the quantitative value of its productivity; a summary of the industries dependent on the Gulf, including shipping, tourism, oil and gas mining, fisheries, recreation, and real estate; the human uses and activities that affect coastal economies; and the economic trends evident in Mexico's drive toward coastal development. This first-of-its-kind reference work will be useful to scientists, economists, industry leaders, and policy makers whose work requires an understanding of the economic issues involved in science, business, trade, exploration, development, and commerce in the Gulf of Mexico.

Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot s- port marine life, generally manifests itself in the spring. Since marine species either die or ee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational shing in the Gulf. Since 2001, the hypoxic zone has averaged 2 1 16,500 km during its peak summer months , an area slightly larger than the state 2 2 of Connecticut, and ranged from a low of 8,500 km to a high of 22,000 km . To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (or Task Force) was formed to bring together represen- tives from federal agencies, states, and tribes to consider options for responding to hypoxia. The Task Force asked the White House Of ce of Science and Technology Policy to conduct a scienti c assessment of the causes and consequences of Gulf hypoxia through its Committee on Environment and Natural Resources (CENR).

Modern Biogeochemistry is aimed to generalize modern ideas of biogeochemical developments during the last decades. It is designed to support a general course in biogeochemistry, and as such, is likely to have a broad market among the many universities and colleges that are adding such courses to their curricula. This book aims to supplement the existing textbooks by providing modern understanding of biogeochemistry, from evolutionary biogeochemistry to practical applications of biogeochemical ideas such as human biogeochemistry, biogeochemical standards and biogeochemical technologies. To a certain extent this textbook is a summary of both scientific results of various authors and classes in biogeochemistry, that have been given to students by authors during the last 5 to 10 years at different universities throughout the world such as Cornell, Moscow, Seoul and Bangkok. Biogeochemistry is becoming an increasingly popular subject for graduate and postgraduate education. Courses in ecology, geography, biology, chemistry, environmental science, public health and environmental engineering all tend to have a biogeochemical component in their syllabuses to a greater or lesser extent.

The coastal tropics comprise some of the most sensitive and yet the most understudied ecosystems in the world. Coastal plains and river valleys are also home to agriculture on a vast scale, and it is not surprising to find that streams and rivers receive the majority of agricultural runoff, carrying the residues of insecticides, fungicides and other pesticides into estuaries and coastal zones. There is a growing awareness of the urgent need to develop strategies to help productive, healthy and economically viable agriculture to coexist with natural resources. Pesticide Residues in Tropical Coastal Ecosystems brings together toxicology experts from around the world to assess pesticide burdens in many of the major food-producing tropical countries. It provides a unique set of case studies, chronicling pesticide usage and its ecotoxicological impact in coastal regions. A practical guide to recent research findings and applications, it is essential reading for environmental professionals, ecotoxicologists, marine chemists and agrochemists.

One of the critical issues of our time is the dwindling capacity of the planet to provide life support for a large and growing human population. Based on a symposium on ecosystem health, Managing for Healthy Ecosystems identifies key issues that must be resolved if there is to be progress in this complex area, such as: Evolving methods for regional ecosystem health assessment employing complex adaptive systems coupled with adaptive technologies to permit accurate determination of changes in regional and global environments Issues and methods for assessing, monitoring, and managing diversity and its impact on human health in the context of climate change, agroecosystems, restoration of forests, politics, culture, and tradition. Leading thinkers in the field provide a coherent synthesis and a benchmark for the practice of this emerging field worldwide. The more than 100 peer-reviewed papers are grouped into three major parts. The first, "Emerging Concepts," explores the diverse meanings of ecosystem health within ecological, socio-economic, and human health perspectives, and the linkages to related concepts such as ecological integrity, sustainable development, and ecological footprints. The second part, "Issues and Methods," introduces methods for assessing and monitoring ecosystem health, including strategies for gaining political and stakeholder input and support for science-based ecosystem management. The final part, "Case Studies," reports experiences of interdisciplinary teams grappling with specific issues in a variety of aquatic and terrestrial ecosystems.

Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.
