Conservation by Proxy: Indicator, Umbrella, Keystone, Flagship, and Other Surrogate Species

The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The bookclarifies terminology and contrasts how different terms are used in the real worldconsiders the ecological, taxonomic, and political underpinnings of these shortcutsidentifies criteria that make for good surrogate speciesoutlines the circumstances where the application of the surrogate species concept shows promiseConservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.
