Piedmont-South Atlantic Coast Cooperative Ecosystem Studies Unit (CESU) -- Texas hornshell, Popenaias popeii in the Black River: Field and laboratory studies of sublethal thermal and hypoxia stress

US Geological Survey is offering a funding opportunity to a CESU Partner for research to identify lethal and sublethal thermal thresholds that can be used to better understand instream flow requirements and target thresholds necessary for Texas hornshell to survive and thrive in the Black River. This work will take place at multiple time scales, depending on specific project objectives – ranging from immediate applications to those with longer-term time horizons.

The USGS is engaged in both a research and technical assistance project in collaboration with US Fish and Wildlife and New Mexico Department of Game and Fish. The research involves determining streamflow and in situ conditions necessary for Texas Hornshell (THS) to survive and thrive in the Black River by examining lethal and sublethal thermal, hypoxia, and salinity thresholds and by collecting and assessing in-stream water-quality conditions. The project also offers technical assistance support because the results will be directly applicable to ongoing oil and gas consultations; influence the interpretation of the Clean Water Act recommendations; and contribute to both the recovery of the THS and to the Candidate Conservation Agreement with Assurances (CCAA) because the results from this research will enable resource managers to make specific flow recommendations.

Deadline: April 30, 2021
