What is NPP? Inconsistent accounting of respiratory fluxes in the definition of net primary production

Functional Ecology, 2005
Primary production represents a globally important flux of carbon between the atmosphere and the biosphere. From an ecological perspective, it measures the rate at which solar energy is stored by plants as organic matter, and is therefore a measure of the rate at which solar energy is captured and made available to the rest of the food chain (Odum 1971)

Improvement of Ecological Footprint Model in National Nature Reserve Based on Net Primary Production (NPP) [PDF]

Sustainability, 2018
An increasing number of nature reserves are being invaded by various development and construction activities, such as energy, resources, and transportation facilities. The ecological footprint model, which enables a quantitative assessment of ecological sustainability, can assess whether human consumption at various spatial scales falls within the ...

Comparing global models of terrestrial net primary productivity (NPP): analysis of the seasonal atmospheric CO₂ signal [PDF]

Global Change Biology, 1999
SummaryEight terrestrial biospheric models (TBMs) calculating the monthly distributions of both net primary productivity (NPP) and soil heterotrophic respiration (RH) in the Potsdam NPP Model Intercomparison workshop are used to simulate seasonal patterns of atmospheric CO2 concentration.

Estimating ocean net primary productivity from daily cycles of carbon biomass measured by profiling floats

Limnology and Oceanography Letters, 2023
The dependence of net primary productivity (NPP), a central metric in ecology and biogeochemistry, on sunlight drives daily cycles in carbon biomass in the ocean's euphotic zone. In this study, we infer NPP from the daily cycle of biomass.
