Project:Acropora cervicornis resilience to ocean acidification The goal of this project was to determine which genotypes of staghorn coral (currently in a nursery) were most resilient to ocean acidification based on their physiology and growth rates. Growth rates were determined by changes in bouyancy weights of the coral fragments after four weeks of exposure to acidified water (pH 7.7). Physiology, photosynthetic and respiration rates, was determined by oxygen consumption and production of the fragments when in the dark (consumption) and when exposed to light (photosynthesis). I also looked a shifts in the microbial communities of the fragments before and after exposure to the acidified water using Biolog Ecoplates. The results showed significant differences in the physiology and growth rates between the coral residing in ambient water vs. acidified water after four weeks; however, no significant differences were found between the genotypes. My internship only enabled me to study the effects after four weeks of exposure, perhaps a longer period of time would have resulted in stronger deviation between the genotypes.
