Genetic Effects of Air Pollutants in Forest Tree Populations [PDF ebook] 
Proceedings of the Joint Meeting of the IUFRO Working Parties Genetic Aspects of Air Pollution Population and Ecological Genetics Biochemical Genetics held in Grohansdorf, August 3-7, 1987

Air pollutants provide environmental conditions that drastically differ in many respects from those to which forest trees are naturally adapted. Leading experts in the field here consider these questions of immediate relevance arising from the changing environment: (1) Do air pollutants introduce effects of selection that differ from those known for populations that are not subject to such stress conditions? (2) If air pollutants introduce quantitatively or even qualitatively novel selective effects, which consequences might arise from the adaptation of forest tree populations to the present conditions as well as for the preservation of adaptability to future conditions? In addition to these questions, concepts for preservation of genetic resources are discussed.
