Mortality rates of trees in Amazonian rainforests have been increasing for at least 20 years. Yet, there have been no real attempts to understand the mechanistic basis of this result. TREMOR will use a combination of forest inventory data analysis and process-based modelling to investigate several hypotheses that could explain the increases in mortality. These hypotheses include (i) increasing wind disturbance, (ii) increasing drought frequency, (iii) increasing liana abundance, (iv) increased competition and (v) faster senescence. Finally, we hope to scale-up the impacts of increasing tree mortality on Amazon-wide carbon storage by using a dynamic global vegetation model.

亚马逊热带雨林的树木死亡率至少20年来一直在上升。然而，还没有真正的尝试去理解这一结果的机制基础。Tremor将结合森林调查数据分析和基于过程的建模来调查几个可以解释死亡率上升的假设。这些假设包括(I)增加风扰，(Ii)增加干旱频率，(Iii)增加藤本植物的丰富度，(Iv)增加竞争和(V)更快的衰老。最后，我们希望通过使用动态全球植被模型来扩大树木死亡率增加对亚马逊地区碳储量的影响。
