Fig. 2From: Projections of regional changes in forest net primary productivity for different tree species in Europe driven by climate change and carbon dioxideChange in net primary productivity (NPP; in megagrams C per hectare per year) for each site averaged over all climate change scenarios for simulations with persistent CO2 effects (left) and acclimation of photosynthesis to [CO 2 ] (right). The environmental zones follow the classification of Metzger et al. (2005)Back to article page
