Shifts in prokaryotic communities and giant sulphur-oxidizing bacteria in response to salmon aquaculture in sub-Antarctic marine sediments

This study examines prokaryotic communities in sub-Antarctic marine sediments affected by salmonid aquaculture in the Cordova Inlet, southern Chile. Using high-throughput sequencing of the 16S rRNA gene, we investigated alpha and beta diversity, as well as prokaryotic roles in sediment biogeochemistry, focusing on rocky seabeds with varying giant sulphur-oxidising bacteria (GSOB) mat coverage
