Book Description
A great many species are threatened by the expanding human population. Though the public generally favors environmental protection, conservation does not come without sacrifice and cost. Many decision makers wonder if every species is worth the trouble. Of what consequence would the extinction of, say, spotted owls or snail darters be? Are some species expendable? Given the reality of limited money for conservation efforts, there is a compelling need for scientists to help conservation practitioners set priorities and identify species most in need of urgent attention. Ecology should be capable of providing guidance that goes beyond the obvious impulse to protect economically valuable species (salmon) or aesthetically appealing ones (snow leopards). Although some recent books have considered the ecosystem services provided by biodiversity as an aggregate property, this is the first to focus on the value of particular species. It provides the scientific approaches and analyses available for asking what we can expect from losing (or gaining) species. The contributors are outstanding ecologists, theoreticians, and evolutionary biologists who gathered for a symposium honoring Robert T. Paine, the community ecologist who experimentally demonstrated that a single predator species can act as a keystone species whose removal dramatically alters entire ecosystem communities. They build on Paine's work here by exploring whether we can identify species that play key roles in ecosystems before they are lost forever. These are some of our finest ecologists asking some of our hardest questions. They are, in addition to the editors, S.E.B. Abella, G. C. Chang, D. Doak, A. L. Downing, W. T. Edmondson, A. S.

Book Description
States today play a major role in implementing and enforcing environmental laws such as the Clean Air Act, Clean Water Act, and the Resource Conservation and Recovery Act. A thirty year review of ESA identified state leadership in species conservation as a necessary element in better conserving the nation‘s imperiled species, yet the theoretical and practical reasons and applications of an enhanced state role are little understood and have not been subjected to any meaningful analysis. This book, for the first time, presents the legal and policy analysis for federalism considerations in implementing ESA. The book undertakes a comprehensive analysis of the economic rationale for federalism in ESA administration; compares administration of ESA to other major environmental statutes; reviews various tools under the existing Act to enhance state role in species conservation; evaluates major case studies to determine roles the state can play in species conservation and recovery; and concludes with policy recommendations to encourage greater state involvement in species conservation.
