Effects of ocean acidification on metamorphosis: brooding and spawning larvae
Abstract. The effects of ocean acidification on metamorphosis were tested using the larvae of a spawning coral, Goniastrea retiformis and a brooding coral Leptastrea cf transversa in Guam. Four treatment levels of pCO 2 were used, corresponding to current levels of atmospheric CO 2 (approximately 38...

Summary: | Abstract. The effects of ocean acidification on metamorphosis were tested using the larvae of a spawning coral, Goniastrea retiformis and a brooding coral Leptastrea cf transversa in Guam. Four treatment levels of pCO 2 were used, corresponding to current levels of atmospheric CO 2 (approximately 380) and three values projected to occur later this century 600, 750 and 1000 ppm). Metamorphosis was not consistently affected by pCO 2 in either species. These results suggest that the mode of reproduction does not affect the larval response to pCO 2 and furthermore, there will be no direct effects of ocean acidification on settlement rates of reef corals, at least in the near future |
