"A leading authority on conservation issues, especially flora and fauna adaptations to rapid climate change, Professor Primack brings a truly global perspective to Nature's rapid response mechanisms. He discusses changes in the Massachusetts habitat that Henry David Thoreau made famous, and describes the limitations of plants and animals to adapt to this era of intense current climate stress. Richard B. Primack is a Professor in the Biology Department at Boston University. He received his B.A. at Harvard University in 1972 and his Ph.D. at Duke University in 1976, and then was a postdoctoral fellow at the University of Canterbury. He has served as a visiting professor at the University of Hong Kong and Tokyo University, and has been awarded Bullard and Putnam Fellowships from Harvard University and a Guggenheim Fellowship. Dr. Primack was President of the Association for Tropical Biology and Conservation, and is currently Editor-in-Chief of the journal Biological Conservation. Twenty-seven foreign-language editions of his textbooks have been produced, with local coauthors adding in local examples. He is an author of rain forest books, most recently Tropical Rain Forests: An Ecological and Biogeographical Comparison, Second Edition (with Richard Corlett). Dr. Primack's research interests include: the biological impacts of climate change; the loss of species in protected areas; tropical forest ecology and conservation; and conservation education. He is currently writing a popular book about changes in Concord since the time of Henry David Thoreau and Walden."
