Updated Checklist of Amphibians and Reptiles at the University of Oklahoma Biological Station at Lake Texoma, Oklahoma

The University of Oklahoma Biological Station (UOBS) was established in 1950 in Marshall Co., Oklahoma along the newly created reservoir, Lake Texoma. Generations of biology students and independent researchers have documented the flora and fauna on the station grounds and surrounding areas. Herein we compare herpetological records for the area published in the 1950s to herpetology course survey events from 1978–1986 and 2008–2019. Overall, species richness has declined precipitously in the last 65+ years, likely due to several local anthropogenic factors such as habitat modification, environmental pollutants, and the spread of amphibian infectious diseases. We also highlight two species that are additions to the UOBS herpetofauna since its inception; one an introduced species and one a range expansion.
