different introduction histories of invasive Australian Acacia species and Paraserianthes lophantha (Fabaceae) in South Africa

Aim The genetic makeup and evolutionary potential of alien species can be profoundly influenced by their introduction history, but without detailed historical records, it can be difficult to ascertain the strength of this historical contingency. We explore how the known introduction histories combined with phylogeographic patterns in the native range have affected the genetic diversity in the invasive range forfive Australian trees introduced to South Africa (Acacia cyclops,Acacia mearnsii, Acacia pycnantha, Acacia saligna and Paraserianthes lophantha).
