摘要/Abstract

Abstract: Drought effects on plants can depend on timing, especially in seasonal ecosystems. Using a mesocosm, we assessed impacts of zero-precipitation timing and duration on six species typical of one of the most widespread alpine grasslands in the Alps.

Key words: Drought seasonality, climate extremes, phenology, soil moisture, leaf length, yellowing, wilting
