This volume gives an insight into what a group of contemporary plankton biologists think about the utility, virtues, strengths and theoretical and practical weaknesses of J.H. Connell's Intermediate Disturbance Hypothesis within the context of phytoplankton ecology. The sequence of papers in this volume moves from particular case studies to more general and finally theoretical approaches.
