Long‐term experimental warming alters community composition of ascomycetes in Alaskan moist and dry arctic tundra
Abstract Arctic tundra regions have been responding to global warming with visible changes in plant community composition, including expansion of shrubs and declines in lichens and bryophytes. Even though it is well known that the majority of arctic plants are associated with their symbiotic fungi,...
