Increased tree mortality linked to droughts and fires is occurring across temperate regions globally. Vegetation recovery has been widely reported; however, less is known about how disturbance may alter forests structurally and functionally across environmental gradients. We examined whether dry forests growing on low-fertility soils were more resilient to coupled extreme drought and severe fire owing to lower tree mortality rates, higher resprouting success and persistence of juveniles relative to wetter forests on more fertile soils.

遭受巨大干扰的重发桉树林中的人口变化和大树损失


全球温带地区因干旱和火灾导致树木死亡率增加。植被恢复已得到广泛报道；然而，人们对干扰如何在环境梯度上改变森林的结构和功能知之甚少。我们研究了生长在低肥力土壤上的干燥森林是否比生长在更肥沃土壤上的湿润森林更能抵抗极端干旱和严重火灾，因为树木死亡率较低，重新发芽成功率较高，幼树的持久性也较高。
