The use of chlorofluorocarbons and other ozone antagonists has been suggested to increase terrestrial UV-B radiation (290-320 nm) by thinning the stratospheric ozone layer. We have have shown that weedy species differ in their response to UV-B radiation and that this radiation significantly influences interaction of weeds with associated crops, weedy neighbours, and other components of their biotic environment. I intend to continue this line of research and explore some new but related areas to advance our holistic 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可使平流层臭氧层变薄，从而增加地面紫外线-B辐射（290-320纳米）。我们已经表明，杂草物种在他们的UV-B辐射的反应不同，这种辐射显着影响相互作用的杂草与相关作物，杂草邻居，和其他组成部分的生物环境。我打算继续这条研究路线，并探索一些新的，但相关的领域，以促进我们的整体理解杂草生态生理学在农业生态环境。
