Resilience of boreal ecosystems assessed using high-frequency records of dissolved organic matter and nitrate in streams

High-latitude ecosystems are subject to a changing disturbance regime, including more frequent fires, thawing permafrost, increasing temperature, and more extreme precipitation events, but ecological responses to these changes remain difficult to predict. Using stream chemistry as an integrator of catchment processes, we are detecting the ecological state of catchments and developing metrics for predicting state change based on high-frequency data collected by instream sensors.
