Research on the effects of extreme rainfall events on ecosystem function has primarily focussed on drought or flooding events, which usually include changes to mean or total rainfall, annually or over a season. However, less is known about the effects of increased rainfall variability without change to mean or total amounts. We investigated the effects of increased variation of water supply on shoot and root biomass as well as the distribution of root biomass of four grassland plant species, grown in monoculture and mixture communities.

供水的变化影响四种温带草原物种在单一栽培和混合条件下的枝条生物量和根深分布

关于极端降雨事件对生态系统功能的影响的研究主要集中于干旱或洪水事件,通常包括每年或整个季节平均或总降雨量的变化。但是,人们对降雨变化率增加而没有改变平均值或总量的影响知之甚少。我们调查了供水量变化对单一种植和混合群落中生长的四种草地植物种类的枝条和根生物量以及根生物量分布的影响。
