Skull morphology and ontogenetic variation of the Southern Giant Petrel Macronectes giganteus (Aves: Procellariiformes)
(Springer, 2019-01)
The Southern Giant Petrel Macronectes giganteus is the largest Procellariidae around the world. Beyond the most striking features on the skull, the strong hooked bill with tubular, dorsally-placed, external nostrils, these ...
Foraging grounds of southern giant petrels (Macronectes giganteus) on the Patagonian shelf
(Springer, 2002-12)
During the 1999 and 2000 breeding seasons we used satellite telemetry to track the foraging movements of four southern giant petrels (Macronectes giganteus) nesting on an island off the Argentine coast (45°08′, 66°03′). ...
Exporting the problem: Issues with fishing closures in seabird conservation
(Elsevier Ltd, 2016-12)
Fisheries management may impact on a range of seabirds’ traits such as foraging behavior. There is an extensive hake fishing closure in Argentine waters (HFC) where trawling is banned. The concentration of fishing effort ...
Is it possible for a Procellariiform to raise two chicks? A case of chick adoption in Southern Giant petrels Macronectes giganteus in the South Shetland Islands, Antarctica
(African Seabird Group, 2010-06)
We report on the adoption of a Southern Giant Petrel Macronectes giganteus chick by a breeding pair on 25 de Mayo Island (King George Island), South Shetland Islands, Antarctica. Our observations showed both chicks received ...
Spatio-temporal overlap between the at-sea distribution of Southern Giant Petrels and fisheries at the Patagonian Shelf
(Springer, 2009-08)
The interactions between seabirds and fisheries pose significant threats for the seabird species such as incidental capture. In contrast, several species of seabirds meet part of their energetic requirements through the ...
Stable isotopes reveal trophic segregation by sex and age in the southern giant petrel in two different food webs
(Inter-Research, 2005-12)
We investigated trophic ecology variation among colonies as well as sex- and age-related differences in the diet of the southern giant petrel Macronectes giganteus, a long-lived seabird that is sexually dimorphic in size. ...
Differential use of the Argentine shelf by wintering adults and juveniles southern giant petrels, Macronectes giganteus, from Patagonia
(Elsevier, 2014-08-27)
To study habitat use and at-sea movements of southern giant petrels (SGP) during non-breeding period, we deployed 15 satellite transmitters (six adults, nine juveniles) at Isla Arce and Isla Gran Robredo colonies in ...
