Colonisation genetics and the tree bumblebee

Ryan Brock, from the University of East Anglia, discusses his paper on the recent colonisation of the UK by the tree bumblebee.

What can several approaches to investigating this species' genetic diversity have tell us about how it made the jump from mainland Europe?

What do this study, and others like it, tell us about the 'genetic paradox of invasion', and how populations can thrive in challenging colonisation situations?
