Figure 1. Conceptual diagram outlining the interactions between ecosystems traits, environmental conditions, management, net primary production (NPP), heterotrophic respiration (Rh), potential net ecosystem production (NEPPOT) and apparent NEP (NEPAPP).

Figure 1

It describes NEPAPP as the product of NEPPOT (= NPP – Rh) and functions of seasonal and short-term environmental f(e) and management f(m) constraints. Dotted lines in f) indicate NEPAPP = NEPPOT.
