The terrestrial organisms of the Gal¿gos Islands live under conditions unlike those anywhere else. At the edge of a uniquely rich mid-ocean upwelling, their world is also free of mammalian predators and competitors, allowing them to live unbothered, exuberant lives.

Long before people traversed the Earth, evolution endowed native species with adaptations to these special conditions and to perturbations like El Ni¿o events and periodic droughts. As the islands have grown ever-more connected with humanity, those same adaptations now make its species vulnerable. Today, the islands are best viewed as one big social-ecological system where the ability of each native organism to survive and reproduce is a product of human activity in addition to ecologicalcircumstances. In this book, William H. Durham takes readers on a tour of Gal¿gos and the
