Table 3.
Morphometric data on one-week-old cysts of The Netherlands Enchelys polynucleata. In vivo measurements of well-formed cysts from specimens transferred from the non-flooded Petri dish culture to Eau de Volvic (French table water); malformed cysts discarded. Measurements in μm. CV – coefficient of variation in %, M – median, Max – maximum, Min – minimum, n – number of cysts investigated, SD – standard deviation, SE – standard error of arithmetic mean, – arithmetic mean.
