When the nature writer Richard Mahler discovers that wild jaguars are prowling a remote corner of his home state of New Mexico, he embarks on a determined quest to see in the flesh a big, beautiful cat that is the stuff of legend—yet verifiably real. Mahler’s passion sets in motion a years-long adventure through trackless deserts, steamy jungles, and malarial swamps, as well as a confounding immersion in centuries-old debates over how we should properly regard these powerful predators: as varmints or as icons, trophies or gods? He is drawn from border badlands south to Panama’s rain forest along a route where the fate of nearly all wildlife now rests in human hands. Mahler’s odyssey introduces him to unrepentant poachers, pragmatic ranchers, midnight drug-runners, ardent conservationists, trance-induced shamans, hopeful biologists, stodgy bureaucrats, academic philosophers, macho hunters, and gentle Maya Indians. Along the way, he is forced to reconsider the true meaning of his search—and the enduring symbolism of the jaguar.

Traditional ecological approaches to species evolution have frequently studied too few species, relatively small areas, and relatively short time spans. In The Coevolutionary Process, John N. Thompson advances a new conceptual approach to the evolution of species interactions--the geographic mosaic theory of coevolution. Thompson demonstrates how an integrated study of life histories, genetics, and the geographic structure of populations yields a broader understanding of coevolution, or the development of reciprocal adaptations and specializations in interdependent species. Using examples of species interactions from an enormous range of taxa, Thompson examines how and when extreme specialization evolves in interdependent species and how geographic differences in specialization, adaptation, and the outcomes of interactions shape coevolution. Through the geographic mosaic theory, Thompson bridges the gap between the study of specialization and coevolution in local communities and the study of broader patterns seen in comparisons of the phylogenies of interacting species.
