Diversity and phylogeny of yeasts in various habitats of the Arctic and Antarctic regions, with descriptions of one new family, five new genera and eighteen new species.

ABSTRACT: The Arctic and Antarctic regions are characterized by low temperatures, high solar irradiation, and successive freezing and thawing cycles. To date, 57 yeast species belonging to 24 genera have been identified as novel taxa initially isolated from Arctic and Antarctic environments. This study comprehensively explored yeast diversity in diverse habitats, including soil, freshwater, seawater, lichens, mosses, vascular plants, dung, feathers, algae, and mushrooms, in the Ny-Ålesund (Arctic) and Fildes regions (Antarctica). Over the past decade, a total of 406 samples were collected, resulting in the isolation of 2215 yeast strains. Molecular analysis revealed 2150 yeast strains across 80 known species in 36 genera. Remarkably, 65 yeast strains - 33 from Antarctica and 32 from the Arctic - wer
