A1 E., T1 Diurnal changes of phytoplankton vertical distribution in a shallow floodplain pool JF Czech Phycology YR 2003 VO 3 IS 1 SP 87 OP 96 UL https://fottea.czechphycology.cz/artkey/fot-200301-0008.php AB The study focused on measurements of selected environmental variables and phytoplankton abundance in a shallow floodplain pool. Vertical gradients of temperature, pH, dissolved oxygen and nutrients and their diurnal changes were found although the depth of the pool was only 80 cm (or 140 cm). Diurnal changes in vertical distribution were observed in the case of Euglenophyta, Cryptophyta, and Chrysophyceae.
