Connectivity, small islands and large distances: the Cellana strigilis limpet complex in the Southern Ocean
Abstract The Southern Ocean contains some of the most isolated islands on Earth, and fundamental questions remain regarding their colonization and the connectivity of their coastal biotas. Here, we conduct a genetic investigation into the Cellana strigilis (limpet) complex that was originally classi...
