Abstract:
... PURPOSE: Climate models predict that amplification of the hydrological cycle results in more extreme (more intensive but less frequent) precipitation events (EPEs) that have larger effects on ecosystem functioning than mean precipitation conditions. Semiarid grassland ecosystems are considered important CH₄ sinks whose functioning is greatly affected by variations in precipitation patterns. An exp ...
