Native Species Fight Back: First Evidence of Coevolution Between Native, Invasive Species

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 Sciences, is thought to provide the first evidence of coevolution between native and invasive plant species.Read more...
