This Project Grant award of $855,911, provided by the National Science Foundation's Biological Sciences program (CFDA 47.074), supports research at the University of Texas at San Antonio (UTSA) to investigate the potential for urban heat islands to facilitate the northward expansion of invasive tropical freshwater fish species in Texas. The key activities include: 1) lab experiments to measure the cold tolerance and growth potential of three tropical fish species, with a subset of these experiments conducted by UTSA undergraduate students; 2) field monitoring of winter water temperatures across a latitudinal climate gradient in Texas to understand urban heat island effects; and 3) integrating the lab and field data into predictive climate models to forecast future invasion risks for the focal fish species. The research will test hypotheses around thermal physiological differences between tropical and temperate fish species, and how urban heat islands may create conditions that enable tropical invasive species to persist and spread northward. The award has a performance period from January 1, 2026 through December 31, 2030.
