Abstract: The combined effects of predicted ocean acidification and global warming on the larvae of the cold-eurythermal spider crab Hyas araneus L. were investigated in 2 populations: a southernmost around Helgoland (North Sea, 54°N) and a northernmost at Svalbard (North Atlantic, 79°N). Larvae were exposed at temperatures of 3, 9 and 15°C to present day normocapnia (380 ppm CO 2 ) and to CO 2 conditions predicted for the near or medium-term future (710 ppm by the year 2100, 3000 ppm by 2300 and beyond). Larval develop… Show more

“…Growth rates were also reduced in early life stages of the barnacle Semibalanus balanoides reared at 1,000 latm (Findlay et al 2010). In larvae from two populations of the spider crab Hyas araneus, extended development times in zoea I and zoea II were recorded at low temperatures of 3°C and the highest CO 2 treatment of 3,000 latm CO 2 , while elevated PCO 2 values reduced larval growth in megalopa but not in zoea I and zoea II (Walther et al 2010). By sampling once per larval stage, the authors concluded that the megalopa stage might be a physiologically sensitive bottleneck.…”

“…An increase in larval mortality and a decrease in hatching success under elevated seawater PCO 2 have been observed in two species of marine copepods (Kurihara et al 2004). Other crustacean larvae showed altered growth and calcification rates at high seawater CO 2 concentrations at 1,200-3,000 latm (Arnold et al 2009, Walther et al 2010. Growth rates were also reduced in early life stages of the barnacle Semibalanus balanoides reared at 1,000 latm (Findlay et al 2010).…”

“…Interpopulation variability in response to ocean acidification is to be expected as a consequence of adaptation to local conditions, and several authors have shown that this can be substantial in some species (Findlay et al 2010a, b;Walther et al 2010Walther et al , 2011. It must be remembered, however, that the prevalence of such examples may not represent the prevalence of trait variability as there are likely to be biases against reporting of non-significant differences between populations, which have also been found (Havenhand and Kurihara, unpublished results).…”
