Abstract:

The paper describes the limits of ecological conditions tolerated by submerged aquatic plants of the isoetid group (lsoëtes lacustris L., Littorella uniflora (L.) Aschers. and Lobelia dortmanna L.) along the Southern Baltic. Investigations were carried out in 74 lakes, grouped according to the geographical criterion, vegetation in the catchment areas and human pressure. It has been demonstrated that Littorella tolerates the widest range of water pH (pH 4.5-9.4), Ca (2.8-32.6 g m-3), and total-P (27-620 mg m-3). Isoëtes withstands total-P concentrations of up to 220 mg m-3, Lobelia only to 100 mg m-3. In lakes with Littorella and Isoëtes the limits of maximum total-P concentrations are outside the range tolerated by Lobelia. Isoetids have become extinct in lakes in which the water pH is permanently below 4.5. Littorella is the most resistant to increased water hardness and total-P concentrations, owing to which it best tolerates the effects of lake calcification and eutrophication.
