Diet of grey-headed albatrosses at the Diego Ramírez Islands, Chile: ecological implications
Abstract: The diet of grey-headed albatrosses at Diego Ramírez, Chile, was analyzed and compared ... to that of the sympatric black-browed albatross. Diet composition was inferred from an analysis of ... . The squid Martialia hyadesi predominated in the diet samples in 2001 and 2002 (89% and 81% of ... reconstituted mass), but was absent from the 2000 samples.

Interannual variability of krill, salp and other zooplankton populations in the South Shetland Island area during Austral summer 1993–1998
Abstract: The summer 1998 AMLR field season followed late-forming but spatially extensive winter ... sea ice in the Antarctic Peninsula region. Overall krill length/maturity composition reflected poor ... recruitment from the past two years. Unusually small juvenile krill in 1998 suggested that survival success ... during the 1993 "salp year". The magnitude of this salp bloom may have resulted from a large ...
