Invasive species are expected to cluster on the "high-return" end of the leaf economic spectrum, displaying leaf traits consistent with higher carbon assimilation relative to native species. Intra-leaf nitrogen (N) allocation should support these physiological differences; however, N biochemistry has not been examined in more than a few invasive species. We measured 34 leaf traits including sev...

Aquatic invasive species (AIS) can cause catastrophic damages to lake ecosystems. Bigheaded carp are one such that pose a current threat Lake Michigan. expected have spatially differentiated impacts on other aquatic in the metapopulation. Policymakers must decide how much invest mitigation or conservation policies, if at all, by understanding invasions impact social welfare wellbeing. Estimates...
