PLANKTONIC CILIATES IN PEAT PONDS OF DIFFERENT ACIDITY (E POLAND)

ABSTRACT

The aim of the investigations was to determine the composition and abundance of the planktonic ciliates occurring in three small peat ponds of different acidity – from 3.2 to 6.2 (south-eastern Roztocze, E Poland). The highest diversity and density of ciliates were noted in high pH (>6) pond, the lowest in low pH ponds. The seasonal changes of ciliate communities in three ponds were quite similar, reaching peak values in October during the mass development of small Scuticociliatida and Prostomatida. The density throughout July was the lowest. Probably in peat ponds the biggest factors limiting the degree of the presence of planktonic ciliates are the pH, conductivity and concentrations of total phosphorus and organic matter.

Key words: peatlands, ponds, pH, plankton, ciliates.
