As long as there are adequate nutrients available, net primary production occurs whenever the mixed layer is shallower than the critical depth.

The remainder, that portion of GPP that is not used up by respiration, is known as the net primary production ( NPP ).
13.
There, net primary production is almost always the desired variable, and estimation techniques involve various methods of estimating dry-weight biomass changes over time.
14.
Higher temperatures increase soil decomposition and if soil decomposition becomes higher than net primary production, global atmospheric carbon dioxide will in turn increase.
15.
About half of the GPP is autotrophically respirated and converted back into DIC . The rest stays in the form of net primary production ( NPP ).
16.
Boreal forests exist currently at higher latitudes where the solar angle is 47 to 63.5 degrees, so solar energy is less intense and net primary production on a per hectare basis is relatively low.

Scott Goetz, a research scientist at the University of Maryland at College Park, has sold two copies of his dissertation, " Modeling Carbon Fluxes, Net Primary Production and Light Utilization in Boreal Forest Stands, " through Dissertation . com.

The overall productivity of a system can be found in an equation where the Net Primary Production, or NPP, is equal to the Gross Primary Production, or GPP, minus the Respiration, or R . The formula is the NPP = GPP-R . The NPP is the overall efficiency of the plants in the ecosystem.
19.
Net primary production is the rate at which all the plants in an ecosystem produce net useful chemical energy; it is equal to the difference between the rate at which the plants in an ecosystem produce useful chemical energy ( GPP ) and the rate at which they use some of that energy during respiration.
