Aquatic CPs of the genera Utricularia and Aldrovanda usually grow in shallow standing waters with a certain concentration of humic acids and tannins (i.e., dystrophic waters).
Humic acids were found to be essential for normal growth and development in Aldrovanda vesiculosa (Ashida, 1937; Kaminski, 1987b) and Utricularia vulgaris (Kosiba, 1992b) but facultative in other species (Pringsheim & Pringsheim, 1967; see Luttge, 1983).
Aldrovanda vesiculosa is an aquatic CP with the steepest growth polarity between the apex and senescent basal end.
Ion uptake by Aldrovanda vesiculosa shoots was studied in 6-8-hour experiments (Adamec, unpubl.).
Table VIII Effect of zooplankton feeding, addition of Carex rhizomes, or a combination of the two on the growth of Aldrovanda vesiculosa in a greenhouse.
Drosera capensis and Aldrovanda vesiculosa absorbed organic substances from 14C-labeled Daphnia prey (Fabian-Galan & Salageanu, 1968).
Aldrovanda vesiculosa is able to take up a substantial amount of organic substances from its prey.
