However, few experimental studies have explicitly tested this by comparing traits between invasive and noninvasive species in their native range instead of in the nonnative range.<br />• We used native plant material of 14 European congeneric pairs of herbaceous<br />species that were all introduced to North America, and of which one species per<br />pair is invasive.<br />• In our germination and common garden experiment with and without fertilizer<br />addition, the invasive species germinated faster, produced more biomass and had<br />a higher proportion of flowering plants than the noninvasive congeners.<br />• Our results indicate that species traits, which lead to a high plant performance in the native range, can confer pre-adaptation to become invasive. We suggest that such traits may be especially relevant for use in risk-assessment protocols before<br />introduction elsewhere. 2010 eng van Kleunen, Mark
