The diet of Weddell seals in McMurdo Sound, Antarctica as determined from scat collections and stable isotope analysis
Stable isotope and dive data analyses indicated that while most seals foraged predominantly on pelagic fish and squid, some juveniles concentrated on shallow benthic Trematomus spp. Expand
The development of diving behavior in juvenile Weddell seals: pushing physiological limits in order to survive
The hypothesis that the foraging efficiency of younger seals is reduced relative to that of adults, owing to physiological and morphological constraints on aerobic dive duration, is supported and suggests that low juvenile survival might result from behavioral constraints. Expand
Ontogeny of total body oxygen stores and aerobic dive potential in Steller sea lions (Eumetopias jubatus)
It is indicated that juvenile Steller sea lion oxygen stores remain immature for more than a year, and therefore may constrain dive behavior during the transition to nutritional independence. Expand
Evolution of Mammalian Diving Capacity Traced by Myoglobin Net Surface Charge
The convergent evolution of high myoglobin net surface charge in mammalian divers increases intermolecular electrostatic repulsion, permitting higher muscle oxygen storage capacities without potentially deleterious self-association of the protein. Expand
Identification and quantification of carotenoids, tocopherols and chlorophylls in commonly consumed fruits and vegetables.
The carotenoid, tocopherol and chlorophyll metabolic profiles and content of a selection of fruits and vegetables found commonly in the diet, have been determined using a rapid RP-HPLC technique withExpand
Winter habitat use and foraging behavior of crabeater seals along the Western Antarctic Peninsula
We quantified the winter and spring movement patterns and foraging behavior of adult crabeater seals (Lobodon carcinophagus), and the influence of sea ice and bathymetry on their foraging behavior.Expand
Ontogeny of oxygen stores and physiological diving capability in Australian sea lions
Both dive depth and duration appear impacted by the slow development of oxygen stores in Australian sea lions, which has the slowest documented O2 store development among diving mammals. Expand
Movements and diving behavior of weaned Weddell seal (Leptonychotes weddellii ) pups
Routes followed suggest that pups can use the pack ice habitat, but prefer to remain closer to the coastline than do adults. Expand
Diving Heart Rate Development in Postnatal Harbour Seals, Phoca vitulina
This study shows that pups are born with the ability to maintain the lower, more fully developed dive bradycardia during focused diving but do not do so during shorter routine dives. Expand
Upper ocean variability in west Antarctic Peninsula continental shelf waters as measured using instrumented seals
Abstract Temperature profile data for the west Antarctic Peninsula (WAP) continental shelf waters, collected from freely ranging instrumented seals (crabeater, Lobodon carcinophagus and leopard,Expand
