Stress Responses of Marine Organisms
Our research utilizes biochemical, cellular and ecological approaches to better understand the
stress responses of marine and freshwater photosynthetic organisms. Studying
the stress pathways that regulate biotic interactions is important for
discerning not only how aquatic organisms adapt to their environment, but how
aquatic organisms respond to each other. We are particularly interested in evaluating the impacts of
environmental stressors on cellular processes with the ultimate goal of
understanding how this influences ecosystem functionality. Building an
integrated understanding of how events at the cellular level can impact a species'
ecology is important for our ability to predict the impacts of both regional
and global scale climate change.
Corals are benthic organisms; however, their larvae are planktonic and spend hours to weeks (depending on the coral species) dispersed throughout the water column. This planktonic period represents a critical phase in the life cycle of this organism and has a direct impact on subsequent recruitment processes. As coral reefs across the Caribbean decline in coral cover recruitment has been identified as a key process necessary for the recovery of coral reef communities. To better understand the impacts of environmental stressors on coral larval health, we study the physiological and cellular responses of larvae under varying experimental conditions. We are trying to understand how cell stress relates to larval survival, settlement and post-settlement survival.
