The anthropogenic mechanisms and routes by which marine species are carried between remote biogeographic regions have been studied.
This has involved a combination of i) population-genetic approaches to infer population histories and ii) repeated monitoring of sites to document actual arrivals, range extensions and changes in genetic diversity. A particular focus has been on ascidians and bryozoans.
