Data from: Genetic identification of source and likely vector of a widespread marine invader
The identification of native sources and vectors of introduced species informs its ecological and evolutionary history and may guide policies that seek to prevent future introductions. Population genetics represents a powerful set of tools to identify origins and vectors, but can mislead when the na...

The identification of native sources and vectors of introduced species informs its ecological and evolutionary history and may guide policies that seek to prevent future introductions. Population genetics represents a powerful set of tools to identify origins and vectors, but can mislead when the native range is poorly sampled or few molecular markers are used.
