Periodic Reporting for period 1 - iCUE-Forest (Improving tree carbon use efficiency for climate-adapted more productive forests)

Tree carbon-use efficiency (CUE = NPP / GPP ; Manzoni et al., 2018) is defined as the ratio of net (NPP = GPP – Ra) to gross primary production (GPP) and is thus strongly determined by plant respiration (Ra). It is unknown how Ra and thus also CUE will respond to further...
