Stomatocysts are produced specifically by chrysophytes and distributed widely in freshwater environments, with siliceous shells well preserved in deposits. The main characteristics for the identification and classification of stomatocysts include pore, collar, annulus, and ornamentation. Because of their sensitivity to aquatic environmental changes, chrysophyte stomatocysts are broadly used in studies of aquatic environmental change, including reconstruction of paleotemperature and paleohydrology and assessment of lake eutrophication and acidification. Existing studies are mainly conducted in North America and Europe but few investigations exist in other regions. Compared with other bioindicators, the identification of stomatocysts is much more complex, probably limiting their broad application. Future studies should improve the identification and classification methods of stomatocysts in order to promote efficiency of identification and counting. Furthermore, modern investigation of stomatocysts should be strengthened to reveal global stomatocyst diversity and their ecological attributes, particularly in regions outside of Europe and North America. On these bases, applications of stomatocysts in the fields of peatland environmental change and biogeography should be strengthened.
