About the Research.
The Environmental Health Program supports scientists in the Behavioral Toxicology Core Technology Team (CTT) at the Columbia Environmental Research Center. The scientists identify how contaminants alter the behavior of organisms and what implication those changes may have on individuals, populations, and communities.
Behavioral methodology is becoming increasingly important in assessing the health and viability of natural populations to understand the challenges posed by natural stressors and to support conservation and recovery efforts.

Sublethal toxicity testing and sensitive whole organism endpoints, like behavior and neuromotor function, are of emerging importance in the field of ecotoxicology. Behavioral responses are mediated through the integration of neural, neuroendocrine and neuromuscular signals, contributing to complex and highly variable inter-individual responses in exposed organisms. These overarching themes in the field of animal behavior can be universally applied across toxicological agents, model organisms, organism life stage and endpoints.
The Behavioral Toxicology CTT has utilized its behavioral expertise and facilities to study a wide range of questions related to behavior directly related to contaminants - providing tools to better understand the effects of contaminants on behavior and how they might translate to effects on growth, reproduction, and population size.

Current Science Questions and Activities
- International collaboration to standardize the zebrafish dark/light transition test.
- What effects do algal toxins have on fish health including sublethal and behavioral endpoints?
- What effects does thiamine deficiency have on fish behavior and can these effects be reversed with supplementation?
- Does carbamazepine, an anticonvulsant pharmaceutical, alter fish eye development and behavior?

Fishing, Hunting and Subsistence Living Integrated Science Team
The Fishing, Hunting, and Subsistence Living Integrated Science Team focuses on contaminant and pathogen exposures in the environment that could impact the presence and vitality of fish and wildlife populations that drive commercial, recreational and subsistence activities such as hunting and fishing. If actual risks are identified this project will inform how to economically and effectively...
Energy Resources Life Cycle Integrated Science Team
The Energy Resources Life Cycle Integrated Science Team focuses on the potential for environmental contaminant exposures that might originate from energy resource activities including extraction, production, transportation, storage, waste management, and restoration. Perceived health risks to humans and other organisms will be distinguished from actual risks, if any. If actual risks are identified...
Minerals Resources Life Cycle Integrated Science Team
The Minerals Resources Life Cycle Integrated Science Team focuses on contaminant exposures in the environment that might originate from mineral resource activities including, transportation, storage, extraction and waste management. Perceived health risks to humans and other organisms will be distinguished from actual risks, if any. If actual risks are identified the science produced by this team...
Toxins and Harmful Algal Blooms Science Team
The team develops advanced methods to study factors driving algal toxin production, how and where wildlife or humans are exposed to toxins, and ecotoxicology. That information is used to develop decision tools to understand if toxin exposure leads to adverse health effects in order to protect human and wildlife health.
Science activities related to the Behavioral Toxicology Core Technology Team can be found below.
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.
