Zoogeographical relationships of the littoral ascidiofauna at the Antarctic Peninsula, in the Scotia Arc and in the Magellan region

Three Spanish Antarctic research cruises (Ant-8611, Bentart-94 and Bentart-95) were carried out in the South Shetland Archipelago (Antarctic Peninsula) and Scotia Arc (South Orkney, South Sandwich and South Georgia archipelagos) on the continental shelf and upper slope (10-600 m depth). They have co...
