Located in the Piney Woods ecoregion of East Texas and West Arkansas, the lower Sulphur River flows eastward where it joins with the Red River. This river is mid-sized and water levels are highly regulated by dam operations at Wright Patman Lake. Our team is studying how the Sulphur River fish community changes in response to an altered flow regime. Using changes in fish composition, traits of fishes, and environmental data, we are learning how fish communities adapt with implications for Invasive Species Management (Bigheaded carps) and Fish Conservation.

Fishes get their energy (carbon) from aquatic and terrestrial sources. Our study seeks to understand the amount of aquatic and terrestrial carbon that fuels the growth and productivity of different prairie river fishes. This is a collaborative project that was developed with Dr. Rogosch and Dr. Durham. This project is funded by the Texas Parks and Wildlife Department.

Located in the remote Davis Mountains of Texas, Little Aguja Creek is a tiny intermittent stream. This system is home to the only known population of Rio Grande Chub in Texas. Our team is working with TPWD and private landowners to assess the status of this population. Surveys will be used to develop management plans to help maintain the viability of this secluded population. This project was developed in collaboration with Dr. Rogosch. 

San Felipe Creek is a crystal clear, spring fed stream that flows into the Rio Grande. This stream is home to many native fishes including the federally threatened Devils River Minnow. Unfortunately, San Felipe Creek has become overrun with invasive Giant reed and Armored catfishes. Our project is assessing how invasive Giant reed is affecting the stream food web. Additionally, we are learning how these invasive species may impact the Devils River Minnow.
