As explorers and scientists have known for decades, the Neotropics harbor a fantastic array of our planet’s mammalian diversity, from capybaras and capuchins to maned wolves and mouse opossums to sloths and sakis. This biological bounty can be attributed partly to the striking diversity of Neotropical landscapes and climates and partly to a series of continental connections that permitted intermittent faunal exchanges with Africa, Antarctica, Australia, and North America. Thus, to comprehend the development of modern Neotropical mammal faunas requires not only mastery of the Neotropics’ substantial diversity, but also knowledge of mammalian lineages and landscapes dating back to the Mesozoic.
Bones, Clones, and Biomes offers just that—an exploration of the development and relationships of the modern mammal fauna through a series of studies that encompass the last 100 million years and both Central and South America. This work serves as a complement to more taxonomically driven works, providing for readers the long geologic and biogeographic contexts that undergird the abundance and diversity of Neotropical mammals. Rather than documenting diversity or distribution, this collection traverses the patterns that the distributions and relationships across mammal species convey, bringing together for the first time geology, paleobiology, systematics, mammalogy, and biogeography. Of critical importance is the book’s utility for current conservation and management programs, part of a rapidly rising conservation paleobiology initiative.
Though biogeography may be simply defined--the study of the geographic distributions of organisms--the subject itself is extraordinarily complex, involving a range of scientific disciplines and a bewildering diversity of approaches. For convenience, biogeographers have recognized two research traditions: ecological biogeography and historical biogeography.
This book makes sense of the profound revolution that historical biogeography has undergone in the last two decades, and of the resulting confusion over its foundations, basic concepts, methods, and relationships to other disciplines of comparative biology. Using case studies, the authors explain and illustrate the fundamentals and the most frequently used methods of this discipline. They show the reader how to tell when a historical biogeographic approach is called for, how to decide what kind of data to collect, how to choose the best method for the problem at hand, how to perform the necessary calculations, how to choose and apply a computer program, and how to interpret results.
Wildlife Responses to Climate Change is the culmination of a three-year project to research and study the impacts of global climate change on ecosystems and individual wildlife species in North America. In 1997, the National Wildlife Federation provided fellowships to eight outstanding graduate students to conduct research on global climate change, and engaged leading climate change experts Stephen H. Schneider and Terry L. Root to advise and guide the project. This book presents the results, with chapters describing groundbreaking original research by some of the brightest young scientists in America. The book presents case studies that examine:
Each of the eight case studies provides important information about how biotic systems respond to climatic variables, and how a changing climate may affect biotic systems in the future. They also acknowledge the inherent complexities of problems likely to arise from changes in climate, and demonstrate the types of scientific questions that need to be explored in order to improve our understanding of how climate change and other human disturbances affect wildlife and ecosystems.
Wildlife Responses to Climate Change is an important addition to the body of knowledge critical to scientists, resource managers, and policymakers in understanding and shaping solutions to problems caused by climate change. It provides a useful resource for students and scientists studying the effects of climate change on wildlife and will assist resource managers and other wildlife professionals to better understand factors affecting the species they are striving to conserve.
