A comprehensive assessment of fungal communities in various habitats from an ice-free area of maritime Antarctica: diversity, distribution, and ecological trait
Posted on 2022-11-16 - 10:02
Abstract Background In the ice-free area of maritime Antarctica, fungi are the essential functioning group in terrestrial and marine ecosystems. Until now, no study has been conducted to comprehensively assess fungal communities in various habitats in Antarctica. We aimed to characterize fungal communities in the eleven habitats (i.e., soil, seawater, vascular plant, dung, moss, marine alga, lichen, green alga, freshwater, feather) in the Fildes Region (maritime Antarctica) using next-generation sequencing. Results A total of 12 known phyla, 37 known classes, 85 known orders, 164 known families, 313 known genera, and 320 known species were detected. Habitat specificity rather than habitat overlap determined the composition of fungal communities, suggesting that, although fungal communities were connected by dispersal at the local scale, the environmental filter is a key factor driving fungal assemblages in the ice-free Antarctica. Furthermore, 20 fungal guilds and 6 growth forms were detected. Many significant differences in the functional guild (e.g., lichenized, algal parasite, litter saprotroph) and growth form (e.g., yeast, filamentous mycelium, thallus photosynthetic) existed among different habitat types. Conclusion The present study reveals the high diversity of fungal communities in the eleven ice-free Antarctic habitats and elucidates the ecological traits of fungal communities in this unique ice-free area of maritime Antarctica. The findings will help advance our understanding of fungal diversity and their ecological roles with respect to habitats on a neighbourhood scale in the ice-free area of maritime Antarctica.
