WebJan 15, 2024 · Responses of gross primary productivity to environmental factors. The initial hypothesis was that the responses of GPP to T, VPD, W, L, CI, and CO 2 were all significant and nonlinear even though the variables are correlated to some extent both temporally and spatially. The underlying mechanisms of such responses are discussed in … WebNet Primary Productivity (NPP), or the production of plant biomass, is equal to all of the carbon taken up by the vegetation through photosynthesis (called Gross Primary Production or GPP) minus the carbon that is lost to respiration. NPP = GPP - respiration In terrestrial systems, NPP is often calculated by determining the annual carbon storage
