Influence of krill availability on humpback whale breeding success
Abstract: The abundance of the Antarctic krill (Euphausia superba) has been declining in the ... in the sea surface temperature observed in the region. Thus, the performance (reproduction and ... survival) of the krill consumers may be compromised. In the present study, we investigated the reproductive ... success of humpback whales (Megaptera novaeangliae) from Breeding Stock G in relation to krill density ...

Oiled penguins observed at Bird Island, South Georgia, 1992/1993
Abstract: In the first observation of oiled seabirds at Bird Island, South Georgia since the ... station was opened in 1975, six freshly-oiled penguins (one chinstrap, five gentoos) were recorded ashore ... in July and August 1993. Because gentoo penguins feed very close inshore in winter they must have ... of the oil. Large concentrations of penguins were seen in this area by a US research cruise in June ...
