8.04.02 - Genetic, biochemical and physiological processes
Sharing the present knowledge on the effects of anthropogenic pollution on forest trees and ecosystems (natural, managed, tree plantations) represents the primary aim of this working group in order to locate research needs and stimulate novel research concepts and activities.
Risk assessment is to be consolidated on a mechanistic basis. To this end, structural and functional clarification of stress response is to guide cause/effect scaling within trees (relating molecular regulation to biochemical/physiological processes) and towards the stand, ecosystem/landscape and regional/global level.
Hereby, abiotic and biotic interactions, i.e. between pollutants and climatic and edaphic factors, as well as competitors, pathogens/endophytes, herbivores and soil microorganisms (incl. mycorrhizae) demand for particular attention.
Knowledge on "mechanisms of action" of pollutants and of plant performance is to be examined for "indicator development" and usability for differential stress diagnosis.
The significance of pollution as a component of climate change and impact factor on global resource cycling, with consequences for carbon sequestration of forest ecosystems, production efficiency of renewable, biogenic resources, and hence, post-Kyoto policies, requires increasing awareness in research.
Focus is to be directed, therefore, not only on industrialized, but increasingly also on industrially developing regions of the world (e.g. East Asia, South America and Africa).
