Microsatellite data (39 loci) from Antarctic fur seals and Subantarctic fur seals, used in the paper: "The genetic legacy of extreme exploitation in a polar vertebrate" Abstract Understanding the effects of human exploitation on the genetic composition of wild populations is important for predicting species persistence and adaptive potential.
