Comparative analysis of bacterial diversity in accumulated snow and exposed sediments across Antarctic Islands.

ABSTRACT: The Antarctic continent hosts exceptional niches, making it an ideal environment for studying polyextremophilic microorganisms. These organisms are uniquely shaped by the geographic niches and variations in soil types. Here we present, a culture-independent approach using DNA metabarcoding to assess the bacterial communities associated with accumulated snow and exposed sediments across different Antarctic islands situated in the Larsemann Hills, Antarctica. The exposed sediments (ES) were found to be more diverse than the accumulated snow (AS) sediments as represented by the alpha diversity metrics. Out of the total 303 amplicon sequence variants (ASVs) found at the genus level, 93 were unique to accumulated snow sediments and 97 were unique to exposed sediments. The bacterial community co
