The aim of this study was to determine the energetic cost of a catastrophic moult in southern elephant seals and how this may be influenced by terrestrial habitat and climate. Measurements of heat flux and body surface temperature were used to determine the extent to which environmental drivers su...
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...
Habitat selection and influence on hunting success in female Australian fur seals Article Open access 06 November 2024 Introduction Climate change and other global environmental change drivers will continue to alter ecosystem structure, function and resilience this century1. Plant and animal species can...
Oceanographic parameters other than the ones considered in our analyses are also likely to affect prey distribution and foraging habitat, such as chlorophyll density, which is linked to primary production (Moore and Abbott, 2000), salinity, a key physical parameter of oceans (Caldwell, 1974), or...
Thus, any climate-induced change in the structure of the Southern Ocean phytoplankton communities could ripple through the food chain, generating a trophic cascade and ultimately affecting top predators such as the southern elephant seal (Mirounga leonina)6. The behavior and performance of these ...
climate change or human activity is predicted to further elevate energy requirements due to an increase in locomotor costs required to accommodate a reduction in prey or time available to forage. In this study, we determined the FMRs, total energy requirements, and energy budgets of adult, ...
While much remains to be learned about northern elephant seals, the long-term biologging data set that began during the TOPP program has contributed greatly to our understanding of elephant seal behavior, physiology, and ecology. We now know that adult female elephant seals can dive as deep as...
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...
But this is not because it’s the first time wild Asian Elephants have wandered away from their habitat and headed northward, but for only this time the herd has traveled more than 400 kilometers as far as Kunming. Photographs, videos and stories of the herd’s movement have sparked widespr...
A δ13C pattern emerged for males older than 4 yr: individuals became resident to either a sub- Antarctic (–17 ‰) or an Antarctic (–20 ‰, both values reported as deviations from the Vienna PeeDee Belemnite standard) foraging habitat, with a decrease in intra-individual variability. Up...
