Interannual variability in aboveground net primary production (ANPP) was assessed with long-term (mean = 12 years) data from 11 Long Term Ecological Research sites across North America. The greatest interannual variability in ANPP occurred in grasslands and old fields, with forests the least variable. At a continental scale, ANPP was strongly correlated with annual precipitation. However, interannual variability in ANPP was not related to variability in precipitation. Instead, maximum…

Relationship between variability in aboveground net primary production and precipitation in global grasslands
[1] Aboveground net primary production (ANPP) is strongly correlated with annual precipitation (AP) in grassland ecosystems. However, the relationship between the interannual variation in ANPP and…
Drivers of Variation in Aboveground Net Primary Productivity and Plant Community Composition Differ Across a Broad Precipitation Gradient
Aboveground net primary production (ANPP) is a key integrator of C uptake and energy flow in many terrestrial ecosystems. As such, ecologists have long sought to understand the factors driving…
Interannual variability in net primary production and precipitation.
TLDR
A longterm normalized difference vegetation index (NDVI) data set derived from the Advanced Very High Resolution Radiometer of the National Oceanic and Atmospheric Administration (NOAA), coupled with a historical climate data set, should constitute a useful and powerful data source, because NDVI data are strongly correlated with terrestrial NPP and are frequently used as NPP predictors.
Field-based observations of regional-scale, temporal variation in net primary production in Tibetan alpine grasslands
Net primary production (NPP) is a fundamental process of natural ecosystems. Temporal variation of NPP not only reflects how communities respond to environmen- tal fluctuations, but it also has…
Intra-annual rainfall variability and grassland productivity: can the past predict the future?
Precipitation quantity has been shown to influence grassland aboveground net primary productivity (ANPP) positively whereas experimental increases in of temporal variability in water availability…
Convergence across biomes to a common rain-use efficiency
TLDR
It is shown that RUE decreases across biomes as mean annual precipitation increases, and during the driest years at each site, there is convergence to a common maximum RUE (RUEmax) that is typical of arid ecosystems.
Aboveground net primary production dynamics in a northern Chihuahuan Desert ecosystem
TLDR
Overall, production in this Chihuahuan Desert ecosystem reflected a mix of warm-temperate arid land pulse dynamics during the summer monsoon and non-pulsed dynamics in spring driven by winter soil moisture accumulation similar to that of cool- Temperate regions.
Decreasing Precipitation Variability Does Not Elicit Major Aboveground Biomass or Plant Diversity Responses in a Mesic Rangeland
Abstract Inter- (between years) and intra- (within year) annual variability of precipitation are high on rangelands. We used replicated rainout shelters in a southern tallgrass prairie ecosystem to…
Increasing precipitation event size increases aboveground net primary productivity in a semi-arid grassland
TLDR
Results indicate that semi-arid grasslands are capable of responding immediately and substantially to forecast shifts to more extreme precipitation patterns, and also indicate that soil moisture data indicated that larger events led to greater soil water content and likely permitted moisture penetration to deeper in the soil profile.
Convergence of dynamic vegetation net productivity responses to precipitation variability from 10 years of MODIS EVI
According to Global Climate Models (GCMs) the occurrence of extreme events of precipitation will be more frequent in the future. Therefore, important challenges arise regarding climate variability,…

TLDR
Constraint caused by vegetation structure is the reason why regional ANPP-precipitation models have a steeper slope than long-term models and point out a weakness of exchanging space for time in predicting production patterns.
Consequences of Nonequilibrium Resource Availability Across Multiple Time Scales: The Transient Maxima Hypothesis
TLDR
Such diverse phenomena as overcompensation for herbivory, the intermediate disturbance hypothesis, maximum levels of productivity observed in successional ecosystems, and widespread nitrogen limitation in terrestrial and aquatic ecosystems can be explained by biotic response to shifts in limiting resources.
Net Primary Productivity of Terrestrial Communities: Prediction from Climatological Data
TLDR
Actual evapotranspiration is shown to be a highly significant predictor of the net annual above-ground productivity in mature terrestrial plant communities, and 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 Relationship Between Productivity and Species Richness
TLDR
Reviews of the literature concerning deserts, boreal forests, tropical forests, lakes, and wetlands lead to the conclusion that extant data are insufficient to conclusively resolve the relationship between diversity and productivity, or that patterns are variable with mechanisms equally varied and complex.
Contribution of increasing CO2 and climate to carbon storage by ecosystems in the United States.
TLDR
The effects of increasing carbon dioxide (CO2) and climate on net carbon storage in terrestrial ecosystems of the conterminous United States for the period 1895-1993 were modeled with new, detailed historical climate information, suggesting that processes such as regrowth on abandoned agricultural land or in forests harvested before 1980 have effects as large as or larger than the direct effects of CO2 and climate.
