| Summary: | The classic view of polar ocean foodwebs emphasizes large predators sustained by energy and materials flow through short, efficient diatom-krill-predator food chains. Bacterial activity is generally low in cold polar waters compared to lower latitudes. This view appears to be changing, with new studies of microbial foodwebs in Arctic and Antarctic oceans. We characterized bacterial, archaeal, and eukaryotic community diversity and composition from two depths (near surface and below the euphotic zone) at four sites, including the inshore and offshore, and north and south corners of a sampling grid along the western coast of the Antarctic Peninsula (WAP). We detected up to 2-fold higher richness in microbial eukaryotes at surface and deep inshore northern stations as compared to southern ones but offshore northern and southern stations revealed either no trend or higher richness at depth in the south. In contrast, bacterial and archaeal richness showed no significant differences either inshore or offshore at ... |
