Biomes worldwide are shifting with global change. Biomes whose extents are limited by temperature or precipitation, such as the tundra and savanna, may be particularly strongly affected by climate change. While woody plant encroachment is prevalent across both biomes, its relationship to temperature and precipitation change remains unknown. Here, we quantify the degree to which woody encroachment is related to climate change and identify its main associated drivers.

在苔原和热带稀树草原生物群落的气候变化下，木本植物的侵害加剧

全球生物群落正在随着全球变化而变化。受温度或降水限制的生物群落，如苔原和热带稀树草原，可能会受到气候变化的强烈影响。虽然木本植物入侵在两个生物群落中都很普遍，但它与温度和降水变化的关系仍然未知。在这里，我们量化了森林入侵与气候变化的关联程度，并确定了其主要相关动因。
