Abstract:

These data were generated from a one-time experiment in support of a coral ecophysiology manuscript; published in

Edmunds, PJ (2011) Limnology and Oceanography 56: 2402-2410 doi: 10.4319/lo.2011.56.6.2402

I tested the hypothesis that the effects of high pCO2 and temperature on massive Porites spp. (Scleractinia) are modified by heterotrophic feeding (zooplanktivory). Small colonies of massive Porites spp. from the back reef of Moorea, French Polynesia, were incubated for 1 month under combinations of temperature (29.3 C vs. 25.6 C), pCO2 (41.6 vs. 81.5 Pa), and feeding regimes (none vs. ad libitum access to live Artemia spp.), with the response assessed using calcification and biomass. Area-normalized calcification was unaffected by pCO2, temperature, and the interaction between the two, although it increased 40% with feeding. Biomass increased 35% with feeding and tended to be higher at 25.6 C compared to 29.3 C, and as a result, biomass-normalized calcification statistically was unaffected by feeding, but was depressed 12-17% by high pCO2, with the effect accentuated at 25.6 C. These results show that massive Porites spp. has the capacity to resist the effects on calcification of 1 month exposure to 81.5 Pa pCO2 through heterotrophy and changes in biomass. Area-normalized calcification is sustained at high pCO2 by a greater biomass with a reduced biomass-normalized rate of calcification. This mechanism may play a role in determining the extent to which corals can resist the long-term effects of ocean acidification.

Growth
Data published in Fig. 1A and Fig. 1C of Edmunds, PJ (2011) Limnology and Oceanography 56: 2402-2410.
Biomass and Zooxanthellae
Data published in Fig. 1B and Fig. 2a and b of Edmunds, PJ (2011) Limnology and Oceanography 56: 2402-2410. Zooxanthellae per biomass (as in Fig. 2b) is calculated by dividing total zooxanthellae by biomass. Zooxanthallae per area (as in Fig. 2a) is calculated by dividing total zooxanthellae by area.
