Distribution patterns of organisms are largely determined by their ability to cope with different environmental conditions. For plants, the availability of nutrients, water and light plays a major role. Acquisition of these resources is well studied, but equally important for the species ecology, though less studied, is the ability to avoid losses of the resources, once acquired. Resource losses are closely related to leaf and root mortality and turnover.

生物的分布模式在很大程度上取决于它们适应不同环境条件的能力。对植物来说，养分、水和光的可用性起着主要作用。这些资源的获取已经得到了很好的研究，但对物种生态同样重要的是，一旦获得资源，避免资源损失的能力，尽管研究较少。资源损失与叶片和根系的死亡和周转密切相关。
