Circumpolar habitat use in the southern elephant seal: implications for foraging success and population trajectories. Ecosphere. 2016; 7: n/a-n/a. doi: 10.1002/ecs2.1213Hindell MA, McMahon CR, Bester MN, Boehme L, Costa D, Fedak MA, et al. Circumpolar habitat use in the southern elephant...
One of the largest carnivores (食肉动物) is the southern elephant seal. It can reach 7 metres in length and weigh 5,000kg! That's five times heavier than a polar bear! Much of its weight is from huge layers of fat, which are needed to keep it warm. Its habitat is the southern par...
Linking Southern Elephant Seal activity to bio-optical water-type classes; influence of the phytoplankton community structure After describing each water-type class in terms of phytoplankton community structure, we introduced the SES data and looked at the relationship between the water-type classes and...
The southern elephant seal is a deep-diving, wide-ranging marine predator spe- cies20 that forages in either one of three main habitats: the Antarctic continental shelf, the Kerguelen Plateau or deep open water regions21. Antarctic shelf waters provide prime habitat for both sexes, but females...
The final stage of the moult process in southern elephant seals is characterised by animals remaining on land but moving out of wallows and closer to shore (Boyd et al., 1993; Chaise et al., 2017). Choice of habitat and stage of moult are therefore important factors when considering the ...

In the highly dimorphic southern elephant seal, there are intersexual differences in habitat use; at Iles Kerguelen, males predominantly use shelf waters, while females use deeper oceanic waters. There are equally marked intrasexual differences, with some males using the nearby Kerguelen Plateau, and...
Their habitat, when not in the ocean, is the rocky and sandy beaches where it mates and gives birth.The Southern elephant seal has few predators. The orca and the great white shark, in addition to humans, are its only enemies. Hunted nearly to extinction in the early 1900s, the ...
In the future, we should be able to investigate whether an individual is likely to forage as an adult in the same habitat as its mother. Assuming that the carbon enrichment factor be- tween diet and total dentine organic matter is similar to the estimated enrichment of 4 to 5 ‰ between...
daily individual iron release rates, suggesting the patchy and transient impact of these iron releases on primary producers might differ according to species. Beyond quantitative aspects, pack-ice seals’ contribution to horizontal, vertical and trophic transfers of iron depends on their habitat ...
