Photosynthetic resistance and resilience under drought, flooding and rewatering in maize plants.

Abnormally altered precipitation patterns induced by climate change have profound global effects on crop production. However, the plant functional responses to various precipitation regimes remain unclear. Here, greenhouse and field experiments were conducted to determine how maize plant functional traits respond to drought, flooding and rewatering.

Climatic warming enhances soil respiration resilience in an arid ecosystem.

Precipitation plays a vital role in maintaining desert ecosystems in which rain events after drought cause soil respiration (R) pulses. However, this process and its underlying mechanism remain ambiguous, particularly under climatic warming conditions. This study aims to determine the magnitude and drivers of R resilience to rewetting.
