The use of chlorofluorocarbons and other ozone antagonists has been suggested to increase terrestrial ultraviolet-B radiation (UV-B; 290-320 nm) by thinning the stratospheric ozone layer. We have shown that the influence of this radiation on weedy species could significantly affect their interactions with associated crops, weedy neighbours, and other components of their biotic environment. I intend to continue this line of work and explore some new but related areas to advance our understanding of weed ecophysiology in an agroecological context.

有人建议使用氯氟烃和其他臭氧拮抗剂，通过减薄平流层臭氧层来增加地面紫外线-B辐射(UV-B；290-320 nm)。我们已经证明，这种辐射对杂草物种的影响可能会显著影响它们与相关作物、杂草邻居以及其生物环境的其他组成部分的相互作用。我打算继续这项工作，探索一些新的但相关的领域，以促进我们在农业生态背景下对杂草生态生理学的理解。
