Periphyton Community

The periphyton community (sessile organisms that live attached to surfaces projecting from the bottom of freshwater aquatic environments) in Lake Hovsgol contains hundreds of diatom species. Diatoms are a large group of microscopic algae that grow as single cells or small colonies. This sample was taken as part of a Mongolian-American international partnership to survey the diatom flora of Hovsgol National Park in north-central Mongolia.
