Shifts in mycorrhizal types of fungi and plants in response to fertilisation, warming and herbivory in a tundra grassland
Summary Climate warming is severely affecting high‐latitude regions. In the Arctic tundra, it may lead to enhanced soil nutrient availability and interact with simultaneous changes in grazing pressure. It is presently unknown how these concurrently occurring global change drivers affect the root‐ass...
