<p>A) native range size; B) the number of susceptible and resistant species to <i>Phytophthora</i>; C) use as barrier plants; and D) plant height (m). Different letters indicate groups that differed significantly at <i>p</i><0.05. For barrier plants and susceptibility to <i>Phytophthora</i>, Fisher's exact test for count data was used. Only factors that explained at least 15% of either model are shown.</p
