Do Trace Metal Concentrations in the Upper Columbia River Affect Early Life Stage White Sturgeon?
To understand if contaminants are associated with white sturgeon population declines, U.S. Geological Survey scientists reviewed the life history, physiology, and behavior of white sturgeon, along with recent toxicological studies and existing trace metal data for locations in the Columbia River. The analysis indicated that the highest concentrations of copper and other metals in the Columbia...
Clothianidin Exposure Associated with Changes in Tadpole Behavior
During a laboratory exposure study, tadpole movement decreased with increased concentrations of clothianidin, a neonicotinoid pesticide. Decreased movement could affect a tadpole’s ability to forage, escape predation, and metamorphose before ponds dry.
Behavioral Toxicology — Columbia, Missouri
About the ResearchThe Environmental Health Program supports scientists at the Behavioral Toxicology Laboratory at the Columbia Environmental Research Center. The scientists develop behavioral methods that are used to characterize and quantify effects of contaminants on aquatic organisms. They have utilized these methods with a variety of organisms including larval and juvenile fish and amphibians.
