Abstract

Bukowo Lagoon (known locally as a lake) is one of 9 coastal lakes (or lagoons) situated on the Polish coast of the Baltic Sea. In the frames of an extensive ecological research project carried out in this body of water, among many different topics, an epiphytic assemblage inhabiting reed, Phragmites australis was studied in a three-year period. This plant substrate featured abundantly developing algae, dominated by Bacillariophyta (x = 49 395 cells m-2). The density of Chlorophyta was lower and it amounted to 31 082 cells m-2, on average Cyanophyta occurred sporadically, reaching density of 9 682 cells m-2. Epiphytic microfauna was represented on this substrate by Protozoa, Nematoda, Rotatoria, and Oligochaeta. The dominant group were Protozoa. Three taxa were identified in macrofauna and the dominant species was Cordylophora caspio. Qualitative-quantitative studies of the periphyton indicate that this formation plays a visible ecological role in Bukowo Lake, contributing to enhancement of biodiversity, purification and de-eutrophication of lacustrine waters, providing a food base for other animals, in this number also economically important fish.


Key words: periphyton, coastal lake, coastland
