Stieglmeier, M. For cluster III, Santoro, A. Zheng, Y. Sea animals provide considerable external N inputs for their colony soils and adjacent tundra soils through direct input of their excreta and atmospheric deposition via ammonia volatilization Lindeboom, ; Sun et al. In Antarctica, the productivity of terrestrial ecosystems is strongly limited because of the extremely low nitrogen levels Park et al.

|The results significantly enhanced the understanding of ammonia-oxidizing microbial communities in the tundra environment of maritime Antarctica.
The BS and MS were moderately far away from penguin or seal colonies without the input of the nutrients from sea animal excrements, and their substrates can be provided only through the mineralization of organic matter from local tundra plants.
Kurola, J. Zhao, K. Kalanetra, K. However, the physiochemical properties for tundra soils were strongly influenced by the deposition of penguin or seal excreta under the effects of local microbes Tatur et al. AOA in most extreme environments have lower levels of microbial diversity than in benign ecosystems because of the requirement for specific physiological adaptations which allow organisms to exploit the combination of physical and biochemical stressors Cowan et al.

The findings of this study concerning the abundance, potential activity, and diversity of tundra soil AOA and AOB provide insights into microbial mechanisms driving nitrification in maritime Antarctica.

The colonization by a large number of sea animals, including penguins and seals, plays an important role in the nitrogen cycle of the tundra.
Tundra vegetation including mosses, lichens, and algae, penguin colonies, and their interactions form a special ornithogenic tundra ecosystem Tatur et al.
