Management of Antarctic baleen whales amid past exploitation, current threats and complex marine ecosystems
Abstract As baleen whales recover from severe exploitation, they are probably subject to a wide variety of threats within the Antarctic marine ecosystem, including directed take. Here we review both the management and current status of Antarctic baleen whales and consider those threats likely to imp...
