Our lab conducts research on a variety of topics related to fish ecology, migration, habitat use and population connectivity. This work generally focuses on using the “natural tag” properties of carbonate hard parts in marine and diadromous fishes to examine patterns of migration, dispersal, and life history dynamics of species with mobile phases. This field has grown exponentially in the past couple of decades, yet significant unknowns remain about highly migratory or dispersive species, particularly in the marine environment. Otolith chemistry has the potential to reveal key information about identity and movement patterns that is essential for the effective management of exploited species and ecosystems.
We are located at the UT Marine Science Institute's Fisheries and Mariculture Laboratory (FAML). The versatile research facilities at FAML include 30,000 square feet of wet and dry labs, running seawater, and a range of experimental and spawning tanks with temperature and photoperiod control and biofiltration. We also work closely with members of the UT Jackson School of Geosciences, which houses an array of analytical instruments including laser ablation ICP-MS (multiple and single collectors), TIMS, and isotope ratio mass spectrometers.
