A preliminary survey of cryobiontic algal communities from Cierva Point (Antarctic Peninsula)
Algal communities colouring snow and ice were studied at fourteen sites on Cierva Point (Danco Coast, Antarctic Peninsula). Chlorophyta were the dominant group in cryobiontic communities, both in species richness and abundance. Cyanobacteria and diatoms, in turn, showed a higher species number at lo...
