Infos

This volume contains papers highlighting the diverse interests of modern ecologists. Areas covered range from physiological and evolutionary ecology to ecosystem ecology. Papers address the longevity of roots, the importance of wind dispersal to the population ecology of nocturnal insects, the different functions of soil fauna, 15N abundance in an old field ecosystem and forest productivity. This volume will be essential for all ecologists.
