NCSE is pleased to offer a free preview (PDF) of James L. Gould and Carol Grant Gould's Nature's Compass: The Mystery of Animal Navigation (Princeton University Press, 2012). The preview consists of chapter 8, "Migration and the Future: Conservation and Extinction," discussing the implications of habitat and climate change for migratory species. "Given that 12% of bird species (including 45% of seabirds), most large whales, and all sea turtles are endangered, we must wonder how well migrants deal with these challenges, and what their long-term prospects look like."
James L. Gould is a professor of ecology and evolutionary biology at Princeton University, and Carol Grant Gould is a science writer who has published widely; together they have written nine earlier books, including The Animal Mind and Animal Architects. The reviewer for Science wrote, "Nature's Compass provides a wonderful account of efforts to unravel the mysteries of animal migration. Effectively drawing on their own experiences and the extensive scientific literature in the field, the Goulds explain what we currently know about how animals locate their positions."
