Graduate Students

Zachary "Winston" Clark

Winston is a Master's student in the Wildlife and Fisheries Science Program at the University of Tennessee School of Natural Resources. His research seeks to determine why some Smallmouth Bass in the Great Smoky Mountains National Park are contaminated with mercury to levels that exceed the EPA's recommendations for consumption. Winston is pairing stable isotope analysis with measurements of mercury concentrations throughout stream foodwebs to determine if variation in mercury trophodynamics between streams explains variation in Smallmouth Bass mercury concentrations.

Jeronimo Silva

Jeronimo is a PhD student in the Comparative and Experimental Medicine program at the University of Tennessee College of Veterinary Medicine. His PhD research is highly collaborative and interdisciplinary. Jeronimo is seeking to understand the cause of enigmatic mass mortalities of mussels in a biodiversity hotspot. He using in-situ experiments, field-based studies, and the demographic information that can be extracted from dead mussel shells to determine if hydrology, disease, harmful algal blooms, or their interactions are associated with mass mortalities

Wilson Xiong

Wilson is a Master's student in the Wildlife and Fisheries Science Program at the University of Tennessee School of Natural Resources. Wilson is studying invasive fishes that threaten native fishes in the global tropics. He is extensively sampling Puerto Rico's stream fish assemblages to determine the spatial extent of these invasions on the island and is conducting an experiment to test the efficacy of an invasive species removal method.

Bonnie Myers

Bonnie is a PhD candidate in the Fisheries, Wildlife, and Conservation Biology program at the North Carolina State University Department of Applied Ecology. Bonnie's work focuses on how severe disturbance events, such as hurricanes and drought, affect fish assemblage composition, how these extreme weather events affect native and non-native species differently, and how these changes impact the value of the resource to communities.

Ámbar Torres Molinari

Ámbar completed a Master's degree in the Fisheries, Wildlife, and Conservation Biology program at the North Carolina State University Department of Applied Ecology in Fall of 2022. Her thesis research sought to understand the trends in longitudinal distribution of American Eel population characteristics, such as density, body length, and sex ratio in rivers of Puerto Rico, and compare these to trends found in temperate regions. The second objective of her research was to document presence of parasite infections in Puerto Rico.

Shawna Mitchell Fix

Shawna completed a Master's degree in the Wildlife and Fisheries Science Program at the University of Tennessee department of Forestry Wildlife and Fisheries in Spring of 2021. Her thesis research described the life history of Laurel Dace (Chrosomus saylori), a federally endangered freshwater minnow that is endemic to headwater streams on Walden Ridge, Tennessee.
