Excited to share our new paper led by Tsinghua Uni ECR Zhang Han: www.science.org/doi/10.1126/.... New model based on eco-evolutionary optimality explains observed seasonal and spatial trends in stem respiration, implies stem CO2 efflux down by >25% by 2100, reducing land carbon emissions.
Thermal acclimation of stem respiration implies a weaker carbon-climate feedback
The efflux of carbon dioxide (CO2) from woody stems, a proxy for stem respiration, is a critical carbon flux from ecosystems to the atmosphere, which increases with temperature on short timescales. Ho...
