Overview

Randomized trial unveils microbial diversity in colored Antarctic snow, indicating ecological implications in climate change.

Key Points

  • This study aims to characterize the microbial communities and their roles in biogeochemical cycles in colored snow in Antarctica.
  • Used metagenomic sequencing on red snow and green snow from the Fildes Peninsula.
  • Assessed β-diversity and relative abundances of bacterial, eukaryotic, and archaeal communities.
  • Identified marker genes linked to carbon, nitrogen, phosphorus, and sulfur cycles.
  • Bacterial communities dominated by Bacteroidota and Pseudomonadota; significant differences in RS and GS species (P < 0.05).
  • Enrichment of different genera and functional pathways: Stutzerimonas in red snow and Janthinobacterium in green snow for denitrification.
  • The microbial network in red snow was more complex and may influence nitrogen runoff due to climate warming.
