Jenn Fair, PhD
Dr. Fair is an ecohydrologist with the Eastern Ecological Science Center at the S.O. Conte Research Laboratory in Turners Falls, MA.
Fair leads an interdisciplinary team of fish ecologists, biologists, and hydrologists working to better understand the ecological impacts of streamflow extremes. Our team builds data systems that allow cooperators to share data, explore data, and visualize model predictions. Check out the USGS Flow Photo Explorer and the larger family os USGS ecoSHEDS data system applications.

Diel temperature signals track seasonal shifts in localized groundwater contributions to headwater streamflow generation at network scale Diel temperature signals track seasonal shifts in localized groundwater contributions to headwater streamflow generation at network scale
Groundwater contributions to streamflow sustain aquatic ecosystem resilience; streams without significant groundwater inputs often have well-coupled air and water temperatures that degrade cold-water habitat during warm low flow periods. Widespread uncertainty in stream-groundwater connectivity across space and time has created disparate predictions of energy and nutrient fluxes across...

Effects of episodic stream dewatering on brook trout spatial population structure Effects of episodic stream dewatering on brook trout spatial population structure
Stream dewatering is expected to become more prevalent due to climate change, and we explored the potential consequences for brook trout (Salvelinus fontinalis) within a temperate forest ecosystem in eastern North America.We estimated fish density within stream pools (n = 386) from electrofishing surveys over 10 years (2012–2021) to compare a stream that exhibits episodic dewatering...

CGS: Coupled growth and survival model with cohort fairness CGS: Coupled growth and survival model with cohort fairness
Fish modeling in complex environments is critical for understanding drivers of population dynamics in aquatic systems. This paper proposes a Bayesian network method for modeling fish survival and growth over multiple connected rivers. Traditional fish survival models capture the effect of multiple environmental drivers (e.g., stream temperature, stream flow) by adding different variables...

Stabilising effects of karstic groundwater on stream fish communities Stabilising effects of karstic groundwater on stream fish communities
Although groundwater exchange processes are known to modulate atmospheric influences on stream temperature and flow, the implications for ecological stability are poorly understood. Here, we evaluated temporal change in stream fish communities across a gradient of groundwater influence defined by karst terrain (carbonate parent materials) within the Potomac River basin of eastern North...

Bedrock depth influences spatial patterns of summer baseflow, temperature and flow disconnection for mountainous headwater streams Bedrock depth influences spatial patterns of summer baseflow, temperature and flow disconnection for mountainous headwater streams
In mountain headwater streams, the quality and resilience of summer cold-water habitat is generally regulated by stream discharge, longitudinal stream channel connectivity and groundwater exchange. These critical hydrologic processes are thought to be influenced by the stream corridor bedrock contact depth (sediment thickness), a parameter often inferred from sparse hillslope borehole...
