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 ...
The California coast provides a unique study system for investigating the effects of warming and habitat quality on the thermoregulatory capacity of the northern elephant seal (NES). In California, island rookeries such as the offshore site at the Farallon Islands National Wildlife Refuge are ...
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...

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...

In most cases, the purpose of animal migration is to find a suitable habitat, and they can travel as far as the climate and food will support them until they reach a safe place to live, according to Zaker, a domestic reading platform. Chen suggested a possible reason behind the Yunnan he...
