Description
Summary: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. Here, we traced the introduction of the Asian seaweed Gracilaria vermiculophylla (Rhodophyta) into estuaries in coastal western North America, the eastern United States, Europe and northwestern Africa by genotyping more than 2500 thalli from 37 native and 53 non-native sites at both mitochondrial and nuclear loci. Overall, greater than 90% of introduced thalli have a genetic signature similar to thalli sampled from the coastline of northeastern Japan, strongly indicating this region served as the principal source of the invasion. Notably, northeastern Japan exported the vast majority of the oyster Crassostrea gigas during the 20th Century.
