Effects of temperature on heat-shock responses and survival of two species of marine invertebrates from sub-Antarctic Marion Island
Abstract This study examined high temperature survival and heat shock protein 70 (Hsp70) responses to temperature variation for two marine invertebrate species on sub-Antarctic Marion Island. The isopod Exosphaeroma gigas Leach and the amphipod Hyale hirtipalma Dana had the same tolerance to high te...
