In savannas, a grass‐dominated ground layer is key to ecosystem function via grass–fire feedbacks that maintain open ecosystems. With woody encroachment, tree density increases, thereby decreasing light in the ground layer and potentially altering ecosystem function. We investigated how light availability can filter individual grass species distributions and whether different functional traits are associated with response to a shade gradient in a landscape experiencing woody encroachment.

阴影沿冠层遮盖梯度改变大草原草层的结构和功能

在稀树草原，草皮为主的地面层是通过维持开放生态系统的草火反馈来实现生态系统功能的关键。随着木质侵蚀，树木密度增加，从而减少了地面层的光并可能改变生态系统功能。我们研究了光的可用性如何过滤单个草种的分布，以及在遭受木质侵蚀的景观中，不同的功能性状是否与对阴影梯度的响应相关。
