Antarctic krill (Euphausia superba) in a warming ocean: thermotolerance and deciphering Hsp70 responses.

The Antarctic krill, Euphausia superba, is a Southern Ocean endemic species of proven ecological importance to the region. In the context of predicted global warming, it is particularly important to understand how classic biomarkers of heat stress function in this species. In this respect, Hsp70s are acknowledged as good candidates.
