root-associated fungal community in changing tundra
Climate warming is severely threatening ecosystems at high latitudes. 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-associated fungal communities, particularly mycorrhizal fungi, and whether changes coincide with shifts in plant mycorrhizal types.This study aims at investigating changes in root-associated fungal communities and mycorrhizal types of the plant community in a 10-year factorial experiment with warming, fertilisation, and grazing exclusion in a Finnish tundra meadow.
