The inhibition of leaf respiration in the light has long been reported at a leaf scale, but recent isotopic evidence suggests that inhibition also occurs at the ecosystem scale. This is important, as inhibition at the ecosystem scale would imply a significant bias in current estimates of ecosystem photosynthesis and respiration, but it is not known… More
Until recently it was assumed that all exchange of methane between forests and the atmosphere takes place at the soil surface, and can be captured by an understory eddy covariance (EC) system. Based on a comprehensive review just published in New Phytologist, it is now clear that all surfaces in a forest—living wood, dead wood,… More
