What makes an invasive plant species invasive? A lot of effort goes in to trying to understand the ecological and evolutionary underpinnings of invasive species. Multiple hypotheses have been put forward such as the novel weapons hypothesis and allelopathy, but what do the data tell us about these concepts? The answer is as nuanced as it is interesting. Join me and Dr. Robert Colautti as we explore novel weapons and allelopathy through the lens of purple loosestrife (Lythrum salicaria) and garlic mustard (Alliaria petiolata).
