Marine systems: A mechanistic understanding of calcification in Puerto Rican coral reefs.

Porites astreoides polyps

The PRCEN Marine group integrates molecular level physiology, imaging, and field studies of live corals and their endosymbionts to better understand the process of calcification and the impact of anthropogenic factors on coral community dynamics. Our three main objectives include:

Objective 1. Identify and characterize the transporters that move ions, particularly Ca2+, HCO3-, or H+, into or out of the calicoblastic space in the coral Porites astreoides.

Objective 2. The role of symbiont composition and photosynthetic capacity on coral calcification rates.

Objective 3. Linking symbiont composition and calcification rates to the demography of a susceptible and resilient coral species along a gradient of anthropogenically induced environmental degradation.
