The percentages of formed cysts and growth rates were monthly estimated and analyzed rhythmometrically by cosinor for 5 clonal cultures of Scripsiella trochoidea Stein grown for 2 years under laboratory conditions, rended as constant as possible from the view point of environmental temperature (24 +/- 1 degree C), lighting (25 microEin m-2 s-1), and artificial seawater. A circannual rhythm is macroscopically apparent and microscopically (by cosinor) validated for 3 of 5 clones. The data of the… CONTINUE READING
