Nitrogen (N) deposition causes compositional shifts in subalpine grassland, which can threaten their high plant species diversity. The effects of the interaction of N deposition and climate change are unknown. What are the independent and joint effects of N deposition, warming and water stress on plant functional group cover in subalpine grassland? Do these results apply to the main grassland types of this region typical of base‐poor and ‐rich soils? What vegetation changes can we expect with the current N critical load limits in a warmer future?

气候变化与氮在高山牧场上的相互作用

氮的沉积会导致亚高山草原的成分变化，从而威胁到其高等植物物种的多样性。氮沉降与气候变化相互作用的影响尚不清楚。氮沉积，变暖和水分胁迫对亚高山草原植物功能群覆盖的独立和联合影响是什么？这些结果是否适用于该地区典型的基础贫瘠和丰富土壤的主要草地类型？在一个温暖的未来中，在当前的N个临界负荷限制下，我们可以期望哪些植被变化？
