1. 我们测试的假设，植被对极端事件的反应是一个功能的营养胁迫的物种存在。一系列物种的营养胁迫耐受性是通过一个正式的程序来确定的，在这个程序中，通过实验室筛选测量的性状是用主成分分析合成的。然后将结果与英国德比郡5个草本植物群落对3种极端事件（霜冻、干旱和火灾）的响应的大规模野外试验结果进行比较。营养胁迫耐受性与抗逆性正相关，与恢复力负相关。研究结果说明了利用实验室数据预测植物对极端事件的田间反应，并表明从高到低的营养胁迫耐受性轴在预测这些反应中可以发挥有效作用。
1. We test the hypothesis that the responses of vegetation to extreme events is a function of the nutrient stress tolerance of species present. The nutrient stress tolerance of a range of species was defined by a formalized procedure in which traits measured by screening in the laboratory were synthesized using principle components analysis.2. Results were then compared with the results from a large-scale field experiment which examined the responses of five herbaceous plant communities in Derbyshire, UK to three extreme events (frost, drought and fire).3. Nutrient stress tolerance was positively correlated with resistance to initial damage and negatively correlated with resilience (speed of recovery). The results illustrate the use of laboratory data to predict the field responses of plants to extreme events and demonstrate that the axis from high to low nutrient stress tolerance can play an effective role in predicting these responses.
