To what extent is evolution in introduced plant species generating unique biological entities? A study using two Australian weeds.

When European colonists introduced plants to their new homelands, they inadvertently followed a near-perfect recipe for encouraging rapid evolution. Using glasshouse experiments for two Australian weeds, the aim of this project will be to find out whether differences between source and introduced populations are heritable, and to assess the degree of reproductive isolation between source and introduced populations. This will allow us to quantify the extent to which evolution in introduced species is generating unique biological entities. One intriguing possibility is that introduced populations might eventually diverge so far from their source populations that they could be classified as new Australian natives.
