Aquatic mosses of Leptobryum species form unique tower-like pillars of vegetation termed “moss pillars” in Antarctic lakes. Moss pillars have distinct redox-affected sections: oxidative exteriors and reductive interiors. We have proposed that a “pillar” is a community and habitat of functionally interdependent organisms and may represent a mini-biosphere.(More)
Aquatic mosses in the genera Bryum and Leptobryum form unique tower-like “moss pillars” underwater in some Antarctic lakes, in association with algae and cyanobacteria. These are communities with a two-layer structure comprising an oxidative exterior and reductive interior. Although habitats and photosynthetic properties of moss pillars have been reported,(More)
Antarctic “moss pillars” are lake-bottom biocenoses that are primarily comprised of aquatic mosses. The pillars consist of distinct redox-affected sections: oxidative exteriors and reductive interiors. Batteries of SSU rRNA genotypes of eukaryotes, eubacteria, and cyanobacteria, but no archaea, have been identified in these pillars. However, rRNA-based(More)
