Net Primary Productivity of Terrestrial Communities: Prediction from Climatological Data
Rosenzweig ML. 1968. Net Primary Productivity of Terrestrial Communities: Prediction from Climatological Data. The American Naturalist. 102(923):67-74
SUMMARY: Actual evapotranspiration (AE) is shown to be a highly significant predictor of the net annual above-ground productivity in mature terrestrial plant communities. Communities included ranged from deserts and tundra to tropical forests. It is hypothesized that the relationship of AE to productivity is due to the fact that AE measures the simultaneous availability of water and solar energy, the most important rate-limiting resources in phyotosynthesis.
