In July 1987 James David Williams (1941—) moved from the USFWS Office of Endangered Species in Washington, DC, to the USFWS National Fisheries Research Center (currently USGS Southeast Ecological Science Center), in Gainesville, Florida. Williams and graduate students from the University of Florida, on whose committees he served as adjunct professor, began mussel surveys of Florida panhandle rivers. The first was the Apalachicola basin survey, which was undertaken to determine the conservation status of several endemic mussels that were candidates for federal listing as endangered or threatened species.
In 1974, under contract to the USFWS Office of Endangered Species, he conducted a status survey of mussels in eastern Gulf Coast rivers of the southeastern states (Heard 1975a), which was the first systematic survey of eastern Gulf Coast rivers since the mid-1950s. In the proceedings of a conference on the Apalachicola River, Heard published the earliest compilation of Apalachicola mussels (Heard 1977). 9. William H.
