WebA Net Ecosystem Productivity. NEP, or the net change in carbon storage in the ecosystem, includes fluxes from vegetation, detritus, and mineral soil and is an important descriptor of the overall functioning of ecosystems. NEP quantifies carbon accumidation or loss and, because carbon and nutrient cycles are strongly coupled, allows inferences ... WebNet Primary Productivity.
