| Abstract | Comparing the functional traits of co-occurring native and invasive plant species can offer insight regarding mechanisms of invasion. Previous studies have failed to reach a consensus, indicating that the extent of trait differences between native and invasives might depend on the environmental context and on the spatial grain of the analysis. Here we evaluate the scale-dependency of native–invader trait comparisons within the Hawaiian Archipelago, a globally important region of high endemicity and high invasibility. We evaluated trait (e.g. gas exchange, leaf nutrient concentration, specific leaf area) differences locally and regionally (i.e. within and across islands) and found that while invasives are more resource acquisitive at the regional scale, native–invader differences are highly idiosyncratic at localized scales, varying both in direction and magnitude within islands. Our findings clarify how region-wide species comparisons may fail to characterize interactions happening at local scales, thereby misleading or obscuring the mechanisms underlying invasion. |
