Climate change feedbacks to the Arctic carbon cycle 

Our broad interests here relate to how interactions between plants-microbes control carbon and nutrient cycling under both short-term (e.g., widlfires), and long-term (e.g., warming, elevated CO2) disturbances.

Ecosystem response to disturbance: Climate warming is occurring fastest at high-latitudes. Understanding, the impact of chronic climate change, and related increase in wildfire occurrence, is critical for understanding future carbon-climate feedbacks. We address these questions using a well-tested, mechanistic model (ecosys, eg., Grant et al., 2017), which simulates the interdependent physical, hydrological, and biological processes that govern ecosystem responses to perturbation. This model also includes a mechanistic treatment of carbon, water, nitrogen, and phosphorus dynamics within soils, microbes (bacterial, archaea, and fungi), and plants. 

Specific questions we are addressing include,
       1. How does the carbon-cycle response to climate-perturbation differ from short-term warming experiments 
​          relative to long-term climate  change? See here for more information on this study.
       2. 
What are the long-term ramifications of abrupt wildfire disturbance against the backdrop of ongoing climate 
          change across a centennial timescale?
       3. What role does the belowground microbial community play in enabling the recovery of the aboveground       
          community?
