Invasive species such as kudzu, privet and garlic mustard can devastate ecosystems, and, until now, scientists had little reason to believe that native plants could mount a successful defense. A new University of Georgia study shows that some native clearweed plants have evolved resistance to invasive garlic mustard plants–and that the invasive plants appear to be waging a counterattack. The study, published in the early edition of the journal Proceedings of the National Academy of...

U.S. scientists have discovered the invasive garlic mustard plant, over time, loses its primary weapon -- a fungus-killing toxin it injects into the soil. University of Illinois scientists said their study is one of the first to show evolutionary forces can alter the very attributes that give an invasive plant its advantage. Garlic mustard plants are part of the family that includes cabbage and horseradish -- plants that rely on soil fungi for phosphorous, nitrogen and water. For whatever...

Like most invasive plants introduced to the U.S. from Europe and other places, garlic mustard first found it easy to dominate the natives. A new study indicates that eventually, however, its primary weapon "“ a fungus-killing toxin injected into the soil "“ becomes less potent.The study, in Proceedings of the National Academy of Sciences, is one of the first to show that evolutionary forces can alter the very attributes that give an invasive plant its advantage. In fact, the study...
