Zusatztext The author has crafted a book that spans the breadth and depth of research on natural plant populations and their dynamics. I will certainly recommend this publication to new laboratory members, and will undoubtedly find myself flipping to particular chapters prior to embarking on new projects. Informationen zum Autor Gregory P. Cheplick, Ph.D. Professor of Biology, is a plant ecologist at the College of Staten Island, City University of New York. His research is on the population biology of herbaceous plants, including grasses and their fungal endophytes, in relation to abiotic and biotic conditions. Klappentext This book introduces the rapidly growing field of plant evolutionary ecology. It summarizes and synthesizes much primary literature, providing a historical context for the study of populations. It also examines both traditional (common gardens, reciprocal transplants) and modern (molecular genetic) approaches used to address questions about adaptation to abiotic and biotic factors.
