Overview
Emily Bernhardt is an ecosystem ecologist and biogeochemist whose research is principally concerned with tracking the movement of elements through ecological systems. Dr. Bernhardt's research aims to document the extent to which the structure and function of aquatic ecosystems is being altered by land use change (urbanization, agriculture, mining) global change (rising CO2, rising sea levels) and chemical pollution. Ultimately this information is necessary to determine whether and how ecosystem change can be mitigated or prevented through active ecosystem management.

Accelerated carbon cycling after 50 years of warming and increasing hydrologic variability in a temperate stream
Journal Article Limnology and Oceanography · January 2026 AbstractRivers transform and transport much of the organic input they receive from terrestrial ecosystems. This carbon sustains stream food webs and fuels the production and release of carbon dioxide and ...

Journal Article Freshwater Science · December 1, 2025 Watershed urbanization leads to a characteristic set of physical, biological, and chemical stressors that reduce the biological diversity of aquatic insect communities. We examined how aquatic-to-terrestrial subsidies of energy and associated trace metals ... Full text CiteConsequences of dam removal for reservoir carbon storage and emissions.
Journal Article Journal of environmental management · December 2025 Because dams can facilitate high reservoir carbon emissions, reduced emissions have been proposed as a dam removal benefit; however, the impact of removal on carbon balance depends on several gas exchange pathways. We combined literature values with statis ... Full text CiteRecent Grants
