Ebria tripartita (Schumann) Lemmermann, 1899, a non-photosynthetic flagellate was identified from the southern coast of the Caspian Sea in December 2012. Water temperature at the sampling time was 10 ºC.  The abundance of total phytoplankton cells was 3 × 106 Cells.l-1, while E. tripartita with 2 × 10 3 Cells. l-1 included 0.75% of phytoplankton community. Water quality parameters were recorded...

This paper describes the production of supernumerary flagella by flagellates of Naegleria gniberi exposed to sublethal temperature shocks during the amoeba-to-flagellate transformation. When transformed at any constant temperature below 34 C, cells of N. gniberi strain NB-i may develop from 1 to 4 flagella, but biflagellate cells predominate and the average number of flagella per cell in these ...

Transport behaviors of unidentified flagellated protozoa (flagellates) and flagellate-sized carboxylated microspheres in sandy, organically contaminated aquifer sediments were investigated in a small-scale (1 to 4-m travel distance) natural-gradient tracer test on Cape Cod and in flow-through columns packed with sieved (0.5-to 1.0-mm grain size) aquifer sediments. The minute (average in situ ce...

CV5attonella marina, a raphidophycean flagellate, is one of the most toxic red tide phytoplankton and causes seyere damage to fish farming. Recent studies demonstrated that C7iattonella sp. generates superoxide (02'), hydirogen perexide (H202), and hydroxyl radicals ( ・ OH), which may be responsible for the toxicity ef C marina. In this study, we found that other raphidophycean fiagellates such...

The ATP-induced behavior of the unicellular flagellate alga Chlamydomonas reinhardtii was recorded as changes in the redox currents for a coexisting redox marker. The ATP concentration was estimated using the presented compact electrochemical system, which is based on monitoring of the motility of the flagellates.
