✦ Synopsis


Moss-inhabiting rotifers were studied in 2 raised bogs, 2 poor fens (i.e. intermediate between raised bogs and typical fens), 1 typical fen, and 1 base-rich fen, located in the Polesie National Park (eastern Poland). Moss samples were collected from April till November 2007 in monthly intervals. In total, 42 taxa of Monogononta and 26 of Bdelloidea were found. Analysis of variance (ANOVA) detected highly significant differences between the habitats in conductivity (F = 37.19, P < 0.001), total organic content (F = 9.34, P < 0.001), total P (F = 51.71, P < 0.001), and nitrate N (F = 48.98, P < 0.001). The mean density of rotifers was the highest in a bog dominated by Sphagnum angustifolium JENSEN (Durne Bagno), and the lowest in the base-rich fen (Bubnów). In all the studied habitats, the Bdelloidea were the most abundant, accounting for 56 to 85% of the total rotifer density. Canonical correspondence analysis (CCA), made for selected physicochemical parameters and taxa, confirms strong relationships between abiotic conditions and selected rotifer taxa: Habrotrocha angusticolis, Dicranophorus capucinus, Ke ratella serrulata, and Lepadella elliptica.
