Cryophyton of Lake Kalach, Omsk oblast

摘要

The species composition and dynamics of cyanobacteria and algae inhabiting the ice of Lake Kalach (Omsk oblast) have been studied. High abundance and a low floristic similarity with phytoplankton have been discovered. Small-celled cyanobacteria and chlorococcales dominate in number of species and abundance. A new term, "cryophyton," is proposed for photosynthetic organisms living in the ice.
