The response was determined of this plant to: (1) kind of sediment and type of plant community, (2) varying population density, (3) competitive action of Littorella uniflora (L) Aschers., Myriophyllum alterniflorum DC., Carex rostrata Stokes and Juncus bulbosus L. A considerable plasticity, among other things has been demonstrated of individuals under identical phytocoenotic and biotope conditions, advantageous reactions of an oligophilous plant to increasing sediment fertility, and phenotypical plasticity.}, type={Text}, title={The ecology of Lobelia dortmanna L. 1, The plasticity of individuals within a constant depth interval in oligotrophic lakes}, URL={http://rcin.org.pl/Content/80095/PDF/WA058_87733_P2840-T35_Eko-Pol-A-Nr-3-4.pdf}, volume={35}, number={3-4}, journal={Ekologia Polska}, publisher={Polish Scientific Publishers}, keywords={Lobelia dortmanna, macrophyte, isoetid, fecundity, competition, overcrowding stress, phytocoenotic and biotope conditions, oligotrophic lakes}, }
