WebEstimates of primary productivity in aquatic ecosystems are commonly based on variation in O 2 $$ {\mathrm{O}}_2 $$, rather than CO 2 $$ {\mathrm{CO}}_2 $$.The photosynthetic quotient (PQ) is used to convert primary production estimates from units of O 2 $$ {\mathrm{O}}_2 $$ to C. However, there is a mismatch between the theory and …

Productivity (ecology) - Wikipedia

In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume (unit surface) per unit of time, such as grams per square metre per day (g m d ). The unit of mass can relate to dry matter or to the mass of generated carbon. The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity. WebLand use intensity is an important indicator of human activities, so we quantified the land use intensity and five ecosystem services (soil conservation, water conservation, carbon storage, net primary productivity (NPP), and crop production) in 13 subbasins of the Tabu River Basin in an agro-pastoral ecotone in central Inner Mongolia.
