Biography:

    Hudson DeYoe earned his Ph.D. in biology from Bowling Green State University in 1991. He is Professor and Director of the Center for Subtropical Studies at The University of Texas-Pan American. His current research focuses on how human activities affect the coastal waters of the United States. Dr. DeYoe is interested in finding solutions to reduce or avoid impacts to South Texas coastal waters and ecosystems.

Research topics from last 10 years:

  • Long-term changes in water quality of the Lower Rio Grande (on-going)
  • Effects of the Arroyo Colorado on primary producers of the Laguna Madre (on-going)
  • Ecology and conservation of seagrasses in the Laguna Madre (on-going)
  • Stress physiology of seagrasses (on-going)
  • Restoration of the Bahia Grande ecosystem
  • Effects of sewage treatment plant effluent on the seagrass epiphyte community
  • Causes of the persistence of the Texas brown tide
  • Quantification of the importance of wind tidal flat cyanobacterial mats
