Cryptic Biodiversity of Mesophotic Reefs

The cryptobenthos of mesophotic coral reefs is an incredibly diverse community of invertebrates that has yet to be described in the Gulf of Mexico. Studying these communities is challenging as scuba diving has limited bottom time at mesophotic depths and ROV video fails to capture all benthic organisms due to their small size.

 

My Ph.D. research will focus on using Autonomous Reef Monitoring Structures (ARMS) to characterize cryptic biodiversity and population connectivity of mesophotic coral reefs within Flower Garden Banks National Marine Sanctuary (FGBNMS), and determine environmental factors that drive biodiversity hot spots. This project is funded by NOAA and is in collaboration with the Smithsonian Institution National Museum of Natural History.

Biology of Active Off-axis Hydrothermal Vents

An active off-axis hydrothermal vent field was recently discovered 750m east of the East Pacific Rise Axis at 9º 50'N. This vent field in particular is thought to have avoided lava flow from the 2005-2006 eruption, thus serving as a possible source of larvae to recovering on-axis vents. 

Through future investigations, we aim to characterize the biological communities at YBW-Sentry and determine the role of active off-axis vent fields in metacommunity dynamics. I have also deployed ARMS throughout the East Pacific Rise Axis to test if the ARMS metabarcoding approach is consistent with and/or complimentary to the successful Mullineaux sandwich method in characterizing hydrothermal vent metacommunity dynamics.
