Data from: Effects of brooding and broadcasting reproductive modes on the population genetic structure of two Antarctic gastropod molluscs
Life-history characteristics exert a profound influence upon the population structure of many marine organisms. However, relatively few genetic studies have compared direct with indirect-developing species in the same ecosystem or geographic region, and none to our knowledge within an Antarctic sett...
