Short summary
We investigated abundance, potential activity, and diversity of soil ammonia-oxidizing archaea (AOA) and bacteria (AOB) in five Antarctic tundra patches, including penguin colony, seal colony, and tundra marsh. We have found (1) sea animal colonization increased AOB population size.; (2) AOB contributed to ammonia oxidation rates more than AOA in sea animal colonies; (3) community structures of AOB and AOA were closely related to soil biogeochemical processes associated with animal activities.
