Abstract
The Enemy Release Hypothesis (ERH) predicts that non-native species become invasive in a novel range because they have escaped their natural predators. In this study, we test the ERH by quantifying predation of a plant as percent herbivory of the leaves and correlating that to phylogenetic distance to the nearest native species and leaf traits. We found that more novel species tend to have less herbivory, however a lack of species limits our predicting power. We also found that there is a significant link between leaf traits, specifically Specific Leaf Area and Leaf Toughness, which gives us more insight into how these species allocate resources.
