Variability of the pennatae diatom Gomphonema ventricosum Gregory from far eastern lakes
The present study examined by light microscope the morphological variations of 625 specimens of Gomphonema ventricosum Gregory collected from Lake Hövsgöl (Mongolia), Lake Baikal (Russia) and Lake Kurilskoye (Kamchatka, Russia). We classified the specimens into five types with respect to valve outli...
