Caption

One of the most damaging invasive species in history, kudzu, or Japanese arrowroot, found its way from Japan to the southeastern United States, where it is overtaking much of the landscape. An ecological concept known as the Allee effect governs the spread of invasive species and pathogens, according to a Duke University team that has tested the concept in engineered bacteria.
