Altered precipitation patterns resulting from climate change will have particularly significant
consequences in water‐limited ecosystems, such as arid to semi‐arid ecosystems, where …

Arid ecosystems cover∼ 40% of the Earth's terrestrial surface and store a high proportion of
the global nitrogen (N) pool. They are low-productivity, low-biomass, and polyextreme …

Abstract Changes in precipitation regimes can strongly affect soil nitrogen (N) cycling in
terrestrial ecosystems. However, whether altered precipitation regimes may differentially …

Shrub expansion is a global phenomenon that is occurring on savannas, rangelands, and
grasslands. In addition, this is an increasingly documented occurrence in the Arctic …

In arid ecosystems, current‐year precipitation often explains only a small proportion of
annual aboveground net primary production (ANPP). We hypothesized that lags in the …

As global surface temperatures rise, the percentage of total precipitation that falls in extreme
events is increasing in many areas (“rainfall intensification”), including the US Midwest, a …

Given that plant growth is often water‐limited in grasslands, it has been proposed that
projected increases in precipitation could increase plant productivity and carbon …

Evidence supporting water limitation in arid-semiarid ecosystems includes strong
correlations between aboveground net primary production (ANPP) and annual precipitation …

There is considerable uncertainty in the magnitude and direction of changes in precipitation
associated with climate change, and ecosystem responses are also uncertain. Multiyear …

Irrigation and N fertilizer management are important factors affecting crop yield, N fertilizer
recovery efficiency, and N losses as nitrous oxide (N2O) and nitrate (NO3−). Split application …
