Diversity of cyanobacteria and microalgae in coastal terrestrial ecosystems, Lützow-Holm Bay, East Antarctica
Photosynthetic cyanobacteria and microalgae are adapted to various extreme environments (cold, dry and/or ultra-oligotrophic conditions). Continental Antarctica is an extreme environment because of its high latitude, harsh climate and ice cover. The Antarctic terrestrial ecosystem has low biological...
