A comprehensive comparative analysis of bacterial communities within cryoconite holes of Arctic and Antarctic glaciers as a response to global warming changes

Cryoconite holes, water-filled ponds with sediment at the bottom, play a crucial role for glacial microbiological ecosystems. While they have been widely studied in various regions of the world (e.g., the Arctic, Antarctic, Alps, Himalayas, Central Andes), the novelty of the analyses presented here lies in their deeper exploration of metagenomic data. This study provides a comparative analysis of environmental factors influencing microbial biodiversity, with an additional focus on explaining the effects of pollution on bacterial communities.
