Clint Muhlfeld, Ph.D.
I am a Research Aquatic Ecologist for the USGS Northern Rocky Mountain Science Center stationed in Glacier National Park.
Research interests
I specialize in aquatic ecology, fisheries biology, ecohydrology, and conservation biology. My research focuses on understanding the complex interactions between aquatic species and their environments to guide conservation and management of freshwater fisheries and ecosystems. I focus on how human-driven stressors—such as drought, invasive species, and habitat degradation—impact native trout, valuable recreational fisheries, and freshwater ecosystems, particularly in the northern Rocky Mountains of the United States.
My research addresses various scientific and conservation issues, including:
- Predicting the impacts of environmental changes on native trout and their freshwater habitats
- Evaluating the effects of invasive species on native fishes and ecosystem health
- Conducting ecohydrological assessments of drought and water management impacts
- Investigating life history and genetic diversity of native salmonids
- Assessing the status, threats, and conservation of threatened species to inform management needs
I am passionate about multidisciplinary science collaboration and enjoy mentoring graduate students in fisheries and freshwater ecology. I also contribute to regional, national, and international science teams focused on transboundary river management and the sustainable use of freshwater resources. My ultimate goal is to conserve native species and ecosystems for future generations through research-informed management and education.
