en located more on the basis of social factors than on biodiversity needs The use of explicit socioeconomic variables in addition to biodiversity data is particularly important because in marine systems, where fishing is a major threat, ecological criteria and socioeconomic measures are not independent."

Moreover, the authors argue that this quantitative approach can be applied to virtually any coastal region. "Portfolios" of solutions, they say, can be adjusted and presented to decision makers who can then evaluate the costs and benefits of different management options within socioeconomic constraints.

"What we have developed is not the final answer--it's not a characterization of exactly what will happen in the region. It's a new approach," said Sala. "Marine reserves help, but it's dangerous to say that if you create marine reserves the fishery outside will do much, much better. On land, when you create a national park, you preserve an ecosystem and all the species that live in the ecosystem. Nobody created Yellowstone National Park for the purpose of having more bison or more wolves or more bears so that you can keep hunting them outside the park."

The research is part of a larger effort in cooperation with the World Wildlife Fund, Scripps's partner in a decade-long collaboration to apply science to practical solutions for the conservation of the world's imperiled seas. In addition to the World Wildlife Fund, the effort includes cooperation with other nongovernmental organizations and academic institutions to design a network of marine reserves in the Gulf of California and to work with the Mexican government for its implementation. Funding for the research was provided by the Moore Family Foundation, the Tinker Foundation, the Robins Family Foundation, the Gulf of California Program--World Wildlife Fund, N. Roberts, and B. Brummit.
