A review of introduced populations showing evidence of adaptation to their new environments indicated that these introductions retained 81% of the genetic diversity from the native range. Although the two species studied here had exceptionally low native range genetic diversity, introductions of A. populifolia represent a larger percentage loss of genetic diversity than found in any introduction identified in our review. While high genetic diversity may increase the likelihood of invasion success, these species adapted to their new environments with very little neutral genetic diversity, suggesting that even introductions founded by small numbers of individuals have the potential to become invasive.
