Historical abundance and distributions of Salpa thompsoni hot spots in the Southern Ocean and projections for further ocean warming
Abstract In contrast to Antarctic krill Euphausia superba , Antarctic salps ( Salpa thompsoni ) respond positively to warmer water temperatures and have the ability to create massive blooms under favourable conditions. Therefore, they can compete with krill for primary production. Over the last thre...
