CERC’s priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community. Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices.

Southeast Region (SER) Science Workshop: Identifying Science to Meet Administration Priorities and the Needs of Our Stakeholders
The fourth annual SER Science Workshop, held virtually July 13-16, 2021, addressed four administration priorities – underserved communities, tribal engagement, conserving 30% of our lands and waters by 2030, and tackling the climate crisis.
Media Alert: Portions of Missouri River to change color temporarily as USGS releases dye to study endangered pallid sturgeon
Scientists from the U.S. Geological Survey will conduct a dye-trace assessment. For a few hours during this research, several miles of the Missouri river will appear reddish due to non-toxic dye. The red color will dissipate rapidly and will disappear after it travels several miles downstream. During the study, USGS will deploy several boats on the river to monitor how and where the dye moves

Occurrence, fate, and transport of aerially applied herbicides to control invasive buffelgrass within Saguaro National Park Rincon Mountain District, Arizona, 2015–18
The spread of the invasive and fire-adapted buffelgrass (Cenchrus ciliaris L.) threatens desert ecosystems by competing for resources, increasing fuel loads, and creating wildfire connectivity. The Rincon Mountain District of Saguaro National Park addressed this natural resource threat with the use of glyphosate-based herbicides (GBHs). In 2010,...

Modeling the bioavailability of nickel and zinc to Ceriodaphnia dubia and Neocloeon triangulifer in toxicity tests with Natural Waters
We studied biotic ligand model (BLM) predictions of toxicity of nickel (Ni) and zinc (Zn) in natural waters from Illinois and Minnesota USA which had combinations of pH, hardness, and dissolved organic carbon (DOC) more extreme than 99.7% of waters in a nationwide database. We conducted 7-d chronic tests with Ceriodaphnia dubia, and 96-...

Response to Gard et al.'s (2021) Comments on the Critical Review “Polychlorinated Biphenyl Tissue-Concentration Thresholds for Survival, Growth, and Reproduction in Fish”
This response is offered to the critique by Gard et al. (2021) of our meta-analysis of polychlorinated biphenyl (PCB)-induced toxicity data in fish (Berninger and Tillitt 2019). Gard et al. (2021) offered numerous comments, the most substantive suggesting that 1) we should have added no-observable–adverse effect residue (NOAER) data from...
