Out of the Ordinary

Abstract

Galápagos stands out for its vast collection of extreme life: the world’s only tropical albatross, its only flightless cormorants, and its marine iguanas; three colorful species of boobies; and 15 species of giant tortoises, one on each major volcano, except for one especially large volcano that has two. Each of these organisms has evolved adaptations to the unique rigors of life in an isolated archipelago on the equator. As Galápagos has recently grown ever more connected to the world system, many species’ adaptations have become vulnerabilities in the face of human-induced change. Fortunately, long before people arrived, evolution also endowed native species with forms of resilience to local perturbations like El Niño events and periodic droughts. The eight case studies in this book highlight these vulnerabilities and resiliences and argue that the mismatch between them, stemming from human impact, is the core conservation challenge today.
