Science Highlights
Using a mechanistic ecosystem model, ecosys, to demonstrate that static temperature relations cannot accurately predict wetland CH4 production and emission rates due to substrate-mediated microbial and abiotic interactions.
Using a mechanistic land model, Ecosys, to demonstrate that short-term (< 10 year) warming experiments produce emergent ecosystem carbon stock temperature sensitivities inconsistent with multi-decadal responses due to the tightly coupled, nonlinear nature of high-latitude ecosystems
A novel mathematical formulation allows accurate solution of water flow in geometrically complicated soil structures, including overturned soil layers and other soil disturbance.
Rates and controls on CO2 and CH4 production were observed for two contrasting water‐saturated tundra soils within a permafrost‐affected watershed near Nome, AK.
