Abstract

A study of biofouling from the cooling pond of the Chernobyl nuclear power plant and Lake Glubokoe from its exclusion zone of the Chernobyl Nuclear Power Plant (Ukraine) using scanning electron microscopy revealed diatom species Cocconeis сhernobyliensis and Ulnaria gusliakovii, which are new for science. In the shape of its valve, Cocconeis сhernobyliensis is similar to C. pediculus and C. kujanitzkansis, but it differs from them in some quantitative characteristics (number of striae and areolae in 10 µm and number of rows of areolae in striae). Ulnaria gusliakovii is similar in valve shape and quantitative features to U. danica, U. ulna, and U. ulnabiseriata, but differs from the first two in the absence of a central area and the presence of biseriate striae, as well as from U. ulnabiseriata in the absence of the central area.
