The arrangement of flagellar appendages in 19 cryptomonad species was examined and four new flagellar types are described. The first new type has a single row of mastigonemes on both flagella and hairs on the side opposite the mastigonemes. The secon

We postulate that the evolutionary success of those diverse algal groups characterized by secondary endosymbiotic origin of plastids was directly connected to changing atmospheric CO2 in the late Palaeozoic. Atmospheric CO2 levels were reduced to his

The ultrastructure and systematics of two red colored freshwater cryptomonads, Storeatula rhinosa, sp. nov. and Pyrenomonas ovalis, sp. nov., are described for the first time. Storeatula, which had been described from marine waters only, has a single

Electrical coupling between specific neurons is important for proper function of many neuronal circuits. Identified cultured neurons from the snail Helisoma show a strong correlation between electrical coupling and presence of gap junction plaques in

Mitosis and cytokinesis in Katablepharis ovalis, a colorless flagellate, was investigated. Two new flagella are produced prior to prophase, resulting in a motile quadriflagellate cell during mitosis. the inner array of microtubules of the feeding app
