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.

Reactive oxygen species (ROS) are increasingly appreciated as down-stream effectors of cellular damage and dysfunction under natural and anthropogenic stress scenarios in aquatic systems. This comprehensive volume describes oxidative stress phenomena in different climatic zones and groups of organisms, taking into account specific habitat conditions and how they affect susceptibility to ROS damage. A comprehensive and detailed methods section is included which supplies complete protocols for analyzing ROS production, oxidative damage, and antioxidant systems. Methods are also evaluated with respect to applicability and constraints for different types of research. The authors are all internationally recognized experts in particular fields of oxidative stress research. This comprehensive reference volume is essential for students, researchers, and technicians in the field of ROS research, and also contains information useful for veterinarians, environmental health professionals, and decision makers.

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).

This report contains a collection of papers presented at a workshop in Merida, Mexico --- Strengthening Science-Based Decision Making: Sustainable Management of Groundwater in Mexico. The cross-cutting themes of the workshop were the elements or principles of science-based decision making and the role of the scientific community in ensuring that science is an integral part of the decision making process. Papers included in this volume describe the groundwater resources of Mexico’s Yucatan Peninsula, approaches to managing groundwater in Mexico and governmental and scientific institutions concerned with water resources. Other papers discuss US approaches to managing scarce water resources. Participants in the workshop included representatives from leading scientific and academic institutions, federal state and local governments, non-governmental organizations and businesses.

Annotation Biogeochemistry is the study of biological controls on the chemistry of the environment and the geochemical regulation of ecological structure and function. This textbook for undergraduate and graduate students presents an introduction to this field, beginning with its historical development. Topics include, for example, the biogeochemical cycling of macroelements and trace elements, the thermodynamics of bacterial energetics, and the calculation of critical loads for heavy metals in various ecosystems. Bashkin teaches at Moscow State U. in Russia. Annotation (c)2003 Book News, Inc., Portland, OR (booknews.com).

The vulnerability of socio-ecosystem combines the probability of exposure to natural or anthropogenic pressure, sensitivity and resilience. This book presents a systemic view of the diversity of pressures and impacts produced by climate change and human actions. Erosion of biodiversity by changing ocean chemistry, the intensification of global change raises the problem of the adaptation of living resources.

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.
