Study Site: Burns Bog, Vancouver
Purpose: Peatlands are the largest reservoirs of terrestrial carbon (C). In light of projected global warming, understanding energy and water balances are vital for developing restoration strategies to minimise C loss from degraded peatlands. We investigated the role of ecosystem physiology in shifts between climatic (evapotranspiration, air temperature, and vapour pressure deficit) and water limitation (soil moisture and water table depth) of gross primary production (GPP) in a restored peat bog in Vancouver, Canada.
Abstract: We show that water limitation of GPP is caused by reduction in surface conductivity of water vapour. The unique causal analysis (empirical dynamic modelling framework) implied that these changes pushed the ecosystem productivity to be governed by soil moisture in 2019.
The codes, and data used for the analysis can be found here.
