Cryoconite holes on frozen lakes as source of interesting extremophilic and extremotolerant organisms

The key thought of this short communication is biodiversity evaluation of the photo-autotrophic inhabitants of lake cryoconite holes and point out their potencial as extremo-tolerant or even extremophilic organisms that deserve attention. Cyanobacterial diversity of these environments was investigat...

Cyanobacterial diversity of these environments was investigated in cryoconites holes of 2 permanently and 1 sea-sonally ice-covered lakes at James Ross Island.
