Forensic phylogeography of invasion: species exchanged between the U.S. and China
Biological invasions represent a pressing conservation problem. Population genetics can provide a powerful forensic tool for understanding the geographic distribution of invasive species, including the history of invasion and the likely sites of origin within the native range. With the rise of global commerce and biogeographic similarities, China and the southeastern United States have become a major conduit for exchange of species that have become invasive in their respective introduced habitats. These species provide an ideal laboratory for investigating evolutionary hypotheses on the evolution of invasiveness. We have been studying a number of plant and animal species to provide a robust phylogeographic baseline for the study of invasion: half the species are native to China and invasive in the U.S. and half are native to the southeast and invasive in China.
