Forest die-off is predicted to become more frequent with climate change. Our ability to predict these events is poor because we lack knowledge about the underlying physiological mechanisms of tree mortality. Specifically, nonstructural carbohydrate carbon reserves (sugars and starch) are involved in almost all critical physiological processes in plants, yet it remains hotly debated what role these carbon reserves play in the survival and mortality of trees.

据预测，随着气候变化，森林死亡将变得更加频繁。我们预测这些事件的能力很差，因为我们缺乏关于树木死亡的潜在生理机制的知识。具体而言，非结构性碳水化合物碳储备（糖和淀粉）参与了植物几乎所有的关键生理过程，但这些碳储备在树木的生存和死亡中发挥了什么作用仍然存在激烈的争论。
