Communities are naturally constructed over time by a process of species invasion and elimination. The construction process itself, which until very recently has received little attention, may be of fundamental importance to understanding community attributes such as stability, which have received a lot of attention. So the study of community construction should become a rewarding field of mainstream ecological research.  相似文献
