Over the past decade‎,‎ advances in both molecular developmental biology and evolutionary ecology have made possible a new understanding of organisms as dynamic systems interacting with their environments‎.‎ This innovative book synthesizes a wealth of recent research findings to examine how environments influence phenotypic expression in individual organisms ‎(‎ecological development or ‎'‎eco‎-devo‎'‎‎)‎‎,‎ and how organisms in turn alter their environments ‎(‎niche construction‎)‎‎.‎ A key argument explored throughout the book is that ecological interactions as well as natural selection are shaped by these dual organism‎-environment effects‎.‎ This synthesis is particularly timely as biologists seek a unified contemporary framework in which to investigate the developmental outcomes‎,‎ ecological success‎,‎ and evolutionary prospects of organisms in rapidly changing environments‎.‎ Organism and Environment is an advanced text suitable for graduate level students taking seminar courses in ecology‎,‎ evolution‎,‎ and developmental biology‎,‎ as well as academics and researchers in these fields‎.‎
