SURF: Summer Undergraduate Research Focus

Gregory Buck Environmental Microbiology Lab
Dr. Greg Buck, Associate Professor of Biology and Biomedical Sciences

My research focuses on Vibrio vulnificus, a bacterium native to estuarine and marine waters. Specifically, I am interested in how Vibrio vulnificus regulates genes in response to environmental perturbations, and how this organism may go from a free-living state to a biofilm on plants and shellfish, and how these genes effect pathogenicity, leading to potentially-fatal wound infections and septicemia in humans, as well as gastroenteritis.

To work in my lab, a student MUST have taken Microbiology (with a laboratory) at the level of either an allied health or majors course, because V. vulnificus is a BSL2 pathogen, Risk Group 2. A grade of “B” or better is strongly suggested Microbiology, because students must be able to work alone with pathogenic bacteria. Coursework in and Genetics, Biochemistry and /or Molecular Biology is helpful, but not required. Students should not be involved merely to "check off" an activity box for professional/graduate school, and should be able to work independently and as a team member with faculty, graduate, and undergraduate students. Previous undergraduate students have been able to present and publish their work in my lab.

Project: Effect of Environmental Stress on Regulation of Virulence Genes in Vibrio vulnificus

This work entails characterization of various factors that affect genes in the environmental bacterium Vibrio vulnificus. Our specific research studies how the cytolysin/hemolysin gene vvvhA is regulated by alternative sigma factors under stressors including hyperosmolarity, hypersalinity, and oxidative stress. The goal of an undergraduate student is to learn basic microbiological manipulations and perform introductory research suitable for local, regional or perhaps a national meeting (NCUR, SACNAS,ABRCMS, Sigma Xi).

Project: Oyster Reef Food Webs

I am looking for a SURF student to assist with field experiments in oyster reef ecology. We are examining food web interactions between oysters, crabs, and fish and examining how oyster morphology is influenced by predators.

Dr. Gregory Stunz Center for Sportfish Science and Conservation
Dr. Greg Stunz, Professor of Marine Biology

The Center for Sportfish Science and Conservation (CSSC) is directed by Dr. Greg Stunz and its mission is to advance the knowledge of marine sportfish and promote conservation through science-based fisheries management. The CSSC has numerous on-going fisheries projects, and summer interns will work with the CSSC’s team of research staff and graduate students during their internship.  The Center’s philosophy is for interns to gain as much research experience as possible; thus, summer interns will work with on numerous projects throughout the summer. Examples of current projects are listed below.  Dr. Stunz and his research team expect highly motivated students with a passion for research and an eagerness to learn.  Because of the field-intensive nature of these research projects, students also need to be able to work long hours on boats both in inshore and offshore waters.  Please visit our webpage for additional information about our research team and current projects:  www.sportfishresearch.org

Project: Fish community assessment of Texas artificial reefs in the Gulf of Mexico using a remotely operated vehicle (ROV), SCUBA diving, and vertical long line (VLL) sampling techniques

The overall goal of this large-scale project is to evaluate the fish community structure associated with artificial reefs developed under the Texas Artificial Reef Program along the Coastal Bend region of Texas.  Currently, we are studying 15 artificial reef sites in the Gulf of Mexico using a variety of sampling techniques: a VideoRay Pro4 remotely operated vehicle (ROV), SCUBA diving, and vertical long line sampling.  Using these techniques there are two main goals for this project: 1) determine species abundance, species richness, and vertical distribution patterns of fish at reef sites; and 2) determine how physical differences between representative sites (water depth, distance from shore, type, number of and complexity of structures) affect species abundance and richness. 

Project: Tracking spotted seatrout and red drum habitat use in Texas estuaries using acoustic telemetry

The goal of this project is to employ a novel approach (acoustic telemetry with VR2W positioning system) to characterize movement and connectivity of red drum and spotted seatrout at two spatial scales within an estuarine complex.   These assessments will allow us to evaluate temporal changes (diurnal, diel, seasonal) in habitat use and movement.  The specific objectives of this project are 1) characterize the movement of red drum and spotted seatrout in complex seascapes to identify critical habitats and assess the degree of habitat connectivity; and 2) document spatial and temporal shifts in movement at the bay/estuary scale for both species to determine inter-bay and estuarine-coastal connectivity.

Other examples of ongoing CSSC research projects:

  1. Re-opening of a natural tidal inlet: Determination of seasonal abundance and density of nekton near Cedar Bayou pre- and post-opening
  2. Why are Black Drum (Pogonias cromis) starving in Baffin Bay? An ecosystem-based approach
  3. Determining movement patterns of dolphin-fish (Coryphaena hippurus) in the Gulf of Mexico using pop-up archival transmitting (PAT) tags

Dr. Michael Wetz Estuarine and Coastal Ecosystem Dynamics Lab
Dr. Mike Wetz, Assistant Professor of Marine Biology

I am an oceanographer with an interest in understanding how climate and human-driven shifts in phytoplankton production and species composition affect coastal food web structure and function, biogeochemical cycling, and water quality.

Project: Environmental Controls on the Growth of Harmful Algal Bloom Forming Taxa from South Texas Coastal Embayments

The student will establish single cell isolates of several harmful algal bloom (HAB) forming phytoplankton taxa from Oso Bay and Baffin Bay, Texas. Laboratory experiments will be conducted to examine environmental controls on the growth of these HAB species.

Project: Spatial-Temporal Distribution of Bacteria in Two Eutrophic Coastal Embayments of South Texas

The student will quantify bacteria from the water column of two coastal embayments that are experiencing significant water quality degradation.  Bacterial abundance measurements will be combined with geochemical techniques to assess role of autocthonous and allocthonous carbon sources as contributors to water quality degradation.
