Not poles apart: Antarctic soil fungal communities show similarities to those of the distant Arctic
Abstract Antarctica's extreme environment and geographical isolation offers a useful platform for testing the relative roles of environmental selection and dispersal barriers influencing fungal communities. The former process should lead to convergence in community composition with other cold e...
