Grassland aboveground net primary production (ANPP) increases linearly with precipitation in space and time, but temporal models relating time series of ANPP and annual precipitation for single sites show lower slopes and regression coefficients than are shown by spatial models. The analysis of several ANPP time series showed lags in the ecosystem response to increased water availability, which may explain the difference between spatial and temporal models. The lags may result from constraints…

Climate change effects in a semiarid grassland: Physiological responses to shifts in rain patterns
Precipitation legacies in desert grassland primary production occur through previous-year tiller density.
TLDR
Legacies in ANPP were similar in absolute value for both types of precipitation transitions, and their magnitude was a function of the difference between previous and current-year precipitation.
Precipitation timing and magnitude differentially affect aboveground annual net primary productivity in three perennial species in a Chihuahuan Desert grassland.
TLDR
Although several studies have shown ANPP increases with increases in precipitation and soil moisture in desert systems, this was not observed here as a universal predictor of ANPP, particularly in dry years.
Legacies of precipitation fluctuations on primary production: theory and data synthesis
TLDR
The results suggest that ANPP will respond to climate-change-driven alterations in water availability and, more importantly, that the magnitude of the response will increase with time.
Contrasting Effects of Precipitation Manipulations on Production in Two Sites within the Central Grassland Region, USA
In grassland ecosystems, where soil water most frequently controls ecosystem processes, expected changes in precipitation and temperature may have dramatic effects on ecosystem dynamics. Previous…
Risks of Neglecting Phenology When Assessing Climatic Controls of Primary Production
We evaluated the effect that integrating annual aboveground net primary production (ANPP) along different 12-month periods has on temporal models of productivity (ANPP as a linear function of annual…

Climatic controls of aboveground net primary production in semi-arid grasslands along a latitudinal gradient portend low sensitivity to warming
TLDR
It is concluded that forecasted warming likely will affect ANPP in these grasslands, but that predicting temperature effects from natural climatic gradients is difficult, because, unlike precipitation, warming effects can be positive or negative and moderated by shifts in the C3/C4 ratios of plant communities.

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.
Productivity responses to altered rainfall patterns in a C4-dominated grassland
TLDR
Altered rainfall regimes are likely to be an important element of climate change scenarios in this grassland, and the nature of interactions with other climate change elements remains a significant challenge for predicting ecosystem responses to climate change.

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.
Fixed location rain shelters for studying precipitation effects on rangelands
TLDR
This approach allows for a comparison of treatments where only rainfall distribution is altered, and factors to consider include: cost of structures and plot size necessary, quality of water applied to plots; differential animal use of treatments; and management of watering treatments.
