Introduction: Plant-herbivore interactions

This special feature resulted from a symposium entitled "Interactions Between Plants and Their Herbivores," held during the Meeting of the Society of Population Ecology in Ohmi-Shirahama, Shiga, Japan, in October 1999 (Chairperson of Symposium: Professor Emeritus E. Kuno of Kyoto University). This theme emerged from discussions by the organizing committee for this symposium: N. Yamamura, J. Takabayashi, T. Nishida, and N. Ohsaki. Professor Mark D. Rausher of Duke University was invited as a special lecturer. In this series of reports, five of the seven participants illustrate the variation found in plant-herbivore interactions and address some problems inherent in current theory.
