Net Primary Production in the Shortgrass Steppe
2008Net primary production (NPP), the amount of carbon or energy fixed by green plants in excess of their respiratory needs, is the fundamental quantity upon which all heterotrophs and the ecosystem processes they are associated with depend. Understanding NPP is therefore a prerequisite to understanding ecosystem dynamics.

Net primary production and net ecosystem production of a boreal black spruce wildfire chronosequence
Global Change Biology, 2004AbstractNet primary production (NPP) was measured in seven black spruce (Picea mariana(Mill.) BSP)‐dominated sites comprising a boreal forest chronosequence near Thompson, Man., Canada. The sites burned between 1998 and 1850, and each contained separate well‐ and poorly drained stands.

TURC: A diagnostic model of continental gross primary productivity and net primary productivity
Global Biogeochemical Cycles, 1996TURC, a diagnostic model for the estimation of continental gross primary productivity (GPP) and net primary productivity (NPP), is presented. This model uses a remotely sensed vegetation index to estimate the fraction of solar radiation absorbed by canopies, and an original parameterization of the relationship between absorbed solar radiation and GPP ...

Arctic Ocean Net Primary Production Model Code
Contributors listed in alphabetical order Model Description The Takuvik Net Primary Production (TNPP) model is a light photosynthesis model that uses satellite data to estimate the net primary production (NPP) in the Arctic Ocean. The model was run on a Pan-Arctic scale (above 45°N), at 4 km resolution, and comes from the updated depth and wavelengthTakuvik, UQAR

Geographical dimensions of terrestrial net and gross primary productivity
Radiation and Environmental Biophysics, 1978The paper presents a comparative summary of previous attempts by the author to assess and map global primary productivity using environmental parameters as predictors. The individual components of the productivity process, net production, gross production, dark respiration as well as their regional rates are computed for 10 degree latitudinal belts.

Nutrient Limitation Of Net Primary Production In Marine Ecosystems
Annual Review of Ecology and Systematics, 1988The question of nutrient limitation of primary production in estuaries and other marine ecosystems has engendered a great deal of debate. Although nitrogen is often named as the primary limiting nutrient in seawater (3, 17-19, 50, 52, 55, 61, 76, 80), this is by no means universally accepted. Many workers have argued that phosphorus is limiting (58, 71)

Methods of Estimating Belowground Net Primary Production
2000Despite much recent attention over the past 30 years, belowground net primary production (BNPP) remains one of the poorest understood attributes of terrestrial ecosystems (Milchunas and Lauenroth 1992; Nadelhoffer and Raich 1992). Estimates of the ratio of BNPP to net primary production (NPP) across ecosystem types range from less than 0.20 to more ...
