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.

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

Invasive black carp as a reservoir host for the freshwater mollusk parasite Aspidogaster conchicola: Further evidence of mollusk consumption and implications for parasite dispersal

Black Carp (Mylopharyngodon piceus) has invaded the Mississippi River and is a potential threat to native mollusks. During prior diet research, we discovered that the fluke Aspidogaster conchicola, a mollusk parasite, occurs regularly in the gastrointestinal tract of Black Carp. The fluke remains in fish intestines for extended periods after...

Koch’s postulates: Confirming Nannizziopsis guarroi as the cause of yellow fungal disease in Pogona vitticeps

Nannizziopsis guarroi is an ascomycete fungus associated with a necrotizing dermatitis in captive green iguanas (Iguana iguana) and bearded dragons (Pogona vitticeps) across both Europe and North America. Clinical signs of the disease include swelling and lesion formation. Lesions develop from white raised bumps on the skin and progress into...
