Millipedes and centipedes in wetland alder stands in north-eastern Poland
Using soil sampling and subsequent heat extraction of animals, four alder stands in the wetlands of the Biebrza, Narew and Białowieża national parks, north-eastern Poland, were surveyed for millipedes and centipedes. Among 12 millipede species revealed, Xestoiulus laeticollis, Polydesmus complanatus and Craspedosoma rawlinsii occurred and predominated in all alder woods. The centipede fauna was very poor, altogether represented by four species, only Lithobius curtipes being shared by all sites. The myriapod communities from the swampy alder woods (Ribeso nigri Alnetum) at Biebrza and in the Bia³owieŜa Primeval Forest were mainly under the influence of fertility soil parameters (available and total phosphorus contents) while the assemblage from an alder swamp at Narew was largely affected by soil humidity. Apparently, the community from an ash-alder alluvial wood (Fraxino-Alnetum) sampled in the Bia³owieŜa Primeval Forest mostly depended on soil pH. Comparing all available information, the structure of myriapod assemblages seems to be quite similar even over distant regions in Central Europe.
