Heatwave tolerance of a marine polychaete (Hediste diversicolor): physiological and molecular data archive

The aim of this work was to test the effect of long-lasting heatwaves on the intertidal polychaete <em>Hediste diversicolor</em> (24 ºC <em>vs</em> 30 ºC for a month). We analysed the whole-body proteome and carried out fatty acid analysis after 28 days of exposure and then estimated cumulative survival and upper thermal tolerance limits (after 30 days of exposure). Worms' wet weight was also compared between temperatures (after 30 days) to understand if elevated temperature has effects on growth.
