Distribution and habitat conditions of the phytocoenoses of Sphagnum denticulatum Bridel and Warnstorfia exannulata (B., S. and G.) Loeske in Polish Lobelia lakes
Szankowski, M. | Klosowski, S.(Warsaw University, Warsaw (Poland). Dept. of Environmental Botany)
Phytosociological and habitat studies of Sphagnum denticulatum and Warnstorfia exannulata phytocoenoses from Polish Lobelia lakes have been conducted. The present results were compared with data on Isoetes lacustris community. It is demonstrated that both communities of mosses are distinct with respect to their floristic composition. Moreover, they differ significantly from the patches of I. lacustris with regard to many properties of water and substrates. The phytocoenoses of S. denticulatum are associated with softer waters, poorer in Ca2(+), Na(+), NH4(+) and dissolved organic matter, but richer in Fe than those of I. lacustris
