Ecological Genetics and Changes in Atmospheric Chemistry: The Application of Knowledge,ns in both unmanaged and managed ecosystems should be given more serious attention. This chapter reviews research activities in these two areas and suggests where additional research is needed. It focuses on trees and forest ecosystems, as others (Bell et al. Chapter 3, this volume) discuss similar aspects with other plants.

Many of these changes can alter the physiological status of terrestrial vegetation through either inhibition or enhancement of growth and reproduction, thereby influencing the ability of sensitive plants to compete for limit

Genomic Stress, Genome Size, and Plant Adaptation,1988a; Bennett 1985). The processes resulting in turnover of DNA sequences in the genome are not well understood. However, the activity of transposable elements, unequal crossing-over, and saltatory amplifications are generally considered as likely mechanisms.
