ABSTRAKT

A novel construction of a benthic disk was suggested to study development of two groups of aquatic fungi of benthic communities. A long-term exposure of bait-containing microboxes attached to the disk has revealed an intensive accumulation of biomass of typical aquatic oomycetes at the near-bottom level. Experiments with soil oomycetes demonstrated the ability of some of their species to develop both in water and in bottom sediments.
