Research Abstract

Chytrids are one of the most dominant parasites in aquatic ecosystems. We investigated the dynamics of chytrids in lakes, by applying molecular techniques and fluorescence dying. In Lake inba, chytrids appeared throughout a year, infecting various phytoplankton species such as diatoms. Chytrids found to be dominant species among diverse fungi in lakes. Chytrids play important roles not only as parasites of phytoplankton but also as foods for zooplankton, mediating material flows in lakes.
