Changing environment, plant stress and their ecological implications

Evgenios Agathokleous (Hokkaido Research Center, FFPRI)

This English symposium will deal with the effects of changing environment on vegetation and plant ecosystems. The effects of air pollutants, warming, drought, and any other environmental factors will be examined along with the mechanisms of the resulting oxidative stress. This session will particularly welcome new insights on dose response relationships with emphasis on low-level stress and preconditioning, i.e. the role of a low-level exposure in the biological response to a subsequent more massive exposure. Methodologies for protecting vegetation against adverse effects, derivation of critical levels, and risk assessment are also of interest. Studies presented in this session should relate to potential ecological implications. Priority will be given to studies where the effects of changing environment are studied under the influence of interacting abiotic or biotic factors like inter- or intraspecific competition and herbivory.
