The functions of global forests are threatened by the increasing frequency of severe drought. Due to drought inducing reductions in soil nutrient availability, efficiencies of nutrient use and resorption of trees become crucial for forest functions and biogeochemical cycles. However, understanding the dynamics of responses of foliar nutrient use and resorption efficiencies to drought, especially in tropical or subtropical forests, is still limited. Our goal was to detect whether and how the importance of leaf nutrient use and resorption changes across different species in the hot and wet forests when suffering drought stress in different months.

亚热带季风森林严重干旱下树木养分利用和吸收效率减弱的实验证据

严重干旱的频率越来越高，威胁着全球森林的功能。由于干旱导致土壤养分利用率降低，养分利用和树木吸收的效率对于森林功能和生物地球化学循环至关重要。然而，了解叶片养分利用和干旱吸收效率的动态变化，特别是在热带或亚热带森林中，仍然是有限的。我们的目标是检测在不同月份遭受干旱胁迫时，湿热森林中不同物种的叶片养分利用和吸收的重要性是否以及如何发生变化。
