Porcupine Cave has produced an astounding number of fossils. More than 20,000 identified specimens of fossil vertebrates were distributed over more than 200,000 years, spanning at least two glacial–interglacial transitions as well as smaller-scale climatic fluctuations within glacials and interglacials. This book discusses the role paleontology plays in understanding ecosystem dynamics, such as the maintenance of biodiversity, the effects of climate change on biodiversity, and how biodiversity relates to the health of ecosystems. The faunal dynamics that characterize Porcupine Cave climatic transitions typify how ecosystems respond to climatic warming episodes. The book suggests that faunal responses to climate change may be useful as an ecological baseline against which future changes can be measured.
