Habitat use and characterization of the seascape exploited by wintering adult and juvenile Southern Giant Petrels from Patagonia
(World Seabird Union, 2015)
The characterization of the seascape used by top predators helps to understand the functioning of marine systems. The main goals of this study were to 1) analyze habitat use and at-sea movements of adult and first year ...
Oceanographic and biological landscapes used by the Southern Giant Petrel during the breeding season at the Patagonian Shelf
(Springer, 2011-06)
The study of how and why marine animals distribute themselves at sea has important conservation and management implications of the species and their habitats. We characterize the oceanographic and biological landscapes of ...
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 identify age- and sex-specific dietary partitioning and foraging habitat segregation in southern giant petrels breeding in Antarctica and southern Patagonia
(Springer, 2012-03)
We examined the isotopic signatures (δ 13C, δ 15N) of adult body feathers from southern giant petrels Macronectes giganteus collected at two breeding colonies in Antarctica (Potter Peninsula and Cape Geddes) and one in ...
Seascape modeling of southern giant petrels from Patagonia during different life-cycles
(Springer, 2017-03)
Presence-only models such as Ecological Niche Factor Analysis (ENFA) compare distributions of environmental variables and species, generating habitat suitability (HS) maps. Here, we determined the factors affecting ...
Marine debris ingestion by Southern Giant Petrels and its potential relationships with fisheries in the Southern Atlantic Ocean
(Pergamon-Elsevier Science Ltd, 2003-11)
The quantity of litter in the worlds oceans has been steadily increasing over the years. Within the Southern Ocean, the amount of debris increased 100-fold during the early 1990s (Barnes, 2002) and fisheries appear to be ...
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 ...
Characterization of the seascape used by juvenile and wintering adult Southern Giant Petrels from Patagonia Argentina
(Elsevier, 2014-12-16)
The characterization of the seascape used by marine top predators provides a wide perspective of pelagic habitat use and it is necessary to understand the functioning of marine systems. The goal of this study was to ...
Speciation and phylogeography of giant petrels Macronectes
(Academic Press Inc Elsevier Science, 2010-02)
We examine global phylogeography of the two forms of giant petrel Macronectes spp. Although previously considered to be a single taxon, and despite debate over the status of some populations and the existence of minimal ...
