Travis Schmidt is a Research Ecologist for the Wyoming-Montana Water Science Center.
Travis' aims are to better understand how ecosystems respond to natural and human cause disturbances. He researches the effects of metals, pesticides, and other contaminants on aquatic and riparian ecological communities.

Growth of coal mining operations in the Elk River Valley linked to increasing transport of selenium, nitrate, and sulfate into Koocanusa Reservoir
The Koocanusa Reservoir (also called Lake Koocanusa) is a transboundary reservoir that's located in northwestern Montana and southwestern British Columbia, Canada (BC) and encompasses the headwaters of the Kootenai watershed, eventually flowing into the Columbia River. Coal mining has occurred in the Elk River watershed in British Columbia, Canada for more than 100 years. Concentrations of...

Assessment of Mercury and Selenium Accumulation in Upper Colorado River Basin Fish
More than 50 years of existing mercury and selenium concentrations in native and nonnative fish species residing in streams within the Upper Colorado River Basin were compiled and analyzed to provide an understanding of concentrations among different species, sampling years, and locations to determine potential health risks. Concentrations of mercury and selenium were above health benchmarks in 13...

Analyses of contaminant effects in freshwater systems: synthesizing abiotic and biotic stream datasets for long-term ecological research
Fresh water is arguably the most valuable resource on the planet, but human activities threaten freshwater ecosystems. For example, use of synthetic chemicals, such as pesticides, road salts, and nutrients, has led to the ubiquitous contamination of aquatic systems, jeopardizing the integrity of ecological communities. Given the importance biodiversity plays in maintaining ecosystem health and fun
Aquatic Ecology and Contaminants
The Aquatic Ecology and Contaminants Team investigates critical ecological processes operating in aquatic and riparian ecosystems and how these processes are affected by human activities. We address questions through a combination of field studies, laboratory experiments, and modeling, while working at multiple levels of biological organization from cells through ecosystems. Topics include land...
Ecological Responses to Fish Reclamation Treatments
Piscicides have been used in Rocky Mountain stream and lakes to restore native fish populations. In the last two decades concerns over piscicide effects to non-target organisms, primarily aquatic invertebrates, has increased. Although piscicides have been used for more than 70 years the impact to invertebrate assemblages has not been well studied and is largely unknown. Given the importance a...
Potential Toxicity of Multiple Metals Associated with PGE Deposits
Water quality and aquatic life standards that are set by Federal and state regulatory agencies are used to evaluate the quality of our nation’s water and the health of aquatic ecosystems. These standards currently are based on hardness of the water and are determined for single metals, not for mixtures of metals that are typically found in natural systems. Metal mixtures can potentially be more or...
Climate Change and Trout
Cold-water fishes like trout, salmon, and charr are especially vulnerable to shifting conditions related to climate change; for example, warmer temperatures and more variable hydroclimate. Native cutthroat trout of the southern Rocky Mountains now only occupy a tiny fraction of their historic habitats because of stressors such as non-native fishes, habitat fragmentation, and detrimental land...
Effects of Contaminants on Linked Aquatic and Terrestrial Food Webs
Most aquatic insects live in fresh water as larvae and move to land as flying adults to complete their life cycle. Although often ignored, the emergence of adults can transfer the effects of contamination from aquatic to terrestrial ecosystems as the adults are eaten by predators such as spiders, birds, and bats.
