Results/Conclusions - Few differences were found between native and non-native species in a series of comparisons that included: abundance-distribution relationships (i.e. the relationship between the number of sites species occur at versus average abundance within those sites) and site-frequency relationships (i.e. the frequency with which species occupy different numbers of sites within a region). These findings suggest, at least within the regions examined, that non-native species are not occupying the landscape in a way that is fundamentally different from that of native species. Further work, examining these relationships across a greater number of habitats, is needed to determine the generality of these findings.
