Biography

Nikki Dix has been the Research Coordinator at the Guana Tolomato Matanzas National Estuarine Research Reserve (GTM NERR) since 2013. Her research interests involve understanding how estuaries respond to natural and anthropogenic change with the intent of informing natural resource management. Nikki has a Ph.D. from the University of Florida where she was supported by a NERR fellowship to study responses of plankton and oysters to eutrophication in the GTM estuary. As Research Coordinator at the GTM NERR, Nikki establishes research priorities and oversees long-term monitoring in the context of regional, state, and national objectives. Monitoring includes abiotic (e.g., salinity, temperature, oxygen, rainfall, nutrients) and biotic (e.g., salt marsh vegetation, mangroves, plankton, oysters) parameters within the Reserve to provide foundational information about how the ecosystem changes over space and time. Nikki also facilitates activities of visiting researchers and works to develop collaborations between, scientists, managers, educators, and the public.
