EFFECTS OF SATELLITE TRANSMITTERS ON ALBATROSSES AND PETRELS
To minimize device effects, it is suggested that transmitter loads be reduced to a minimum, use of harnesses be avoided, and careful attention be given to limiting handling times during incubation when some species are particularly sensitive to disturbance.
Cephalopod beak guide for the Southern Ocean
The main cephalopod beaks from species found in the diet of predators from the Southern Ocean and adjacent waters are described and 3-D computer images of the most important lower beaks are provided to assist scientists and students interested in identifying cEPhalopods by the means of their beaks.
Patterns in the distribution of myctophid fish in the northern Scotia Sea ecosystem
Analysis of community structure indicated a high level of depth stratification within the myctophids, with evidence of diurnal vertical migration in some, but not all, species, suggesting all life stages may be present in the northern Scotia Sea.
The stomach contents of Patagonian toothfish around South Georgia (South Atlantic)
The study confirms that D. eleginoides is an opportunistic carnivore, and indicates that feeding habits depend on the local availability of food items, as well as factors such as depth and predator size.
Short- and long-term consistency in the foraging niche of wandering albatrosses
Foraging consistency was not related to body condition or level of breeding experience; instead, it may reduce intraspecific competition and be an important characteristic of this population and potentially of pelagic seabirds in general.
Habitat and trophic ecology of Southern Ocean cephalopods from stable isotope analyses
Differences among islands in isotope ratios in the same cephalopod species (higher δ15N and lower δ13C values in South Georgia) were attributed to regional oceanographic processes.
Foraging ecology of Cory’s shearwaters in different oceanic environments of the North Atlantic
Analysis of stomach regurgitations showed that Trachurus picturatus was the main prey for populations exploiting oceanic environments (Azores and Desertas); Sardina pilchardus and Belone belone dominated the diet of birds feeding in neritic areas (Berlengas); and Trachuras trachu- rus, Scomber sp.
Extraction and characterization of collagen from Antarctic and Sub-Antarctic squid and its potential application in hybrid scaffolds for tissue engineering.
Latitudinal and bathymetric patterns in the distribution and abundance of mesopelagic fish in the Scotia Sea
Interannual variation in the diets of two albatross species breeding at South Georgia: implications for breeding performance
The findings suggest that Grey-headed Albatrosses are more reliant on Antarctic Polar Frontal Zone prey (M. hyadesi and Lamprey Geotria australis) whereas Black-browed Albatosses areMore dependent on Antarctic prey (Icefish and Antarctic Krill Euphausia superba).
