Impacts of temperature and acidification on larval calcium incorporation of the spider crab Hyas araneus from different latitudes (54° vs. 79°N)
The combined effects of ocean warming and acidification were compared in larvae from two populations of the cold-eurythermal spider crab Hyas araneus, from one of its southernmost populations (around Helgoland, southern North Sea, 54A degrees N, habitat temperature 3-18A degrees C; collection: Janua...

The combined effects of ocean warming and acidification were compared in larvae from two populations of the cold-eurythermal spider crab Hyas araneus, from one of its southernmost populations (around Helgoland, southern North Sea, 54A degrees N, habitat temperature 3-18A degrees C; collection: January 2008, hatch: January-February 2008) and from one of its northernmost populations (Svalbard, North Atlantic, 79A degrees N, habitat temperature 0-6A degrees C; collection: July 2008, hatch: February-April 2009). Larvae were exposed to temperatures of 3, 9 and 15A degrees C combined with present-day normocapnic (380 ppm CO(2)) and projected future CO(2) concentrations (710 and 3,000 ppm CO(2)).
