Enhancement of the water use efficiency of vegetation is one of the ways in which theNPP of arid ecosystems is influenced. What are the limiting factors for primary productivity?
WebNet Ecosystem Production (NEP), although calculated in the same way (GPP-R), differs from NPP in that NEP accounts for GPP and R in the entire aquatic ecosystem. While in theory estimates of GPP and R made from isolated samples could be scaled up to give ecosystem values, NEP is usually based on measurement methodologies that attempt to account ... WebJun 22, 2024 · Net primary production is defined as the difference between the energy fixed by autotrophs and their respiration, and it is most often equates to increment in biomass per unit of land surface and time.
