Data from: Strong population genetic structure in a broadcast-spawning Antarctic marine invertebrate
Although studies of population genetic structure are commonplace, a strong bias exists towards species from low latitudes and with relatively poor dispersal capabilities. Consequently, we used 280 Amplified Fragment Length Polymorphism (AFLP) bands to explore patterns of genetic differentiation amon...

Although studies of population genetic structure are commonplace, a strong bias exists towards species from low latitudes and with relatively poor dispersal capabilities.
