Abstract
Understanding seasonal and diurnal dynamics of ecosystem respiration (Reco) in forests is challenging, because Reco can only be measured directly during night-time by eddy-covariance flux towers. Reco is the sum of soil respiration (Rsoil) and above-ground respiration (in theory, RAG = Reco − Rsoil). Rsoil can be measured day and night and can provide a check of consistency on Reco, as the difference in magnitude and time dynamic between Reco and Rsoil should be explained by RAG. We assessed the temporal patterns and climatic drivers of Rsoil and Reco in a mature eucalypt woodland, using continuous measurements (only at night for Reco) at half-hourly resolution over 4 years (2014–2017). Our ..
