See Full Interview Transcript

Charles Randklev is a research assistant professor at the Texas A&M Resources Institute, and a long-time student of freshwater mussels, including the endangered Texas hornshell. Here he tells about surveys in the Pecos River and followup studies that together helped show that the hornshell has been suffering from rising salinity in its home streams over the past 30 to 40 years, due to reduced spring and stream inflows.
