<ns3:p>A comparative analysis of the taxonomic and ecological structure of Collembola communities in different types of floodplain forests and meadows of the “Ujście Warty” National Park was carried out. The results indicated that the fauna of Collembola in the studied forests is represented by 85 species belonging to 42 genera and 16 families and, when combined with the literature data, 127 species from 52 genera. There were 66 species of Collembola found in meadows and 67 in forests. Among them, 48 species were found, common to both open and forest habitats. It was also found that the soil environment under forest vegetation has a higher capacity for springtails than under grass vegetation in meadows. Eighteen species of Collembola belonging to the group of rare or unique were found, representing 14.2% of the total number of species in the study area. The average population density of springtail communities in different types of habitats in the study area ranged from 0.63 to 10.4 thousand individuals per m2. The lowest average population density was found in forests (6.52), and the highest in meadows (7.12). A total of 25 dominant species of springtails were identified across all seven study areas, with 14 found in forests and 19 in meadows. In both studied habitat types, only 8 species of Collembola dominated at the same time. Eurytopic species dominate most often, also polytopic forest and polytopic meadow species. However, the taxonomic composition and relative abundance of dominant species differ slightly between forests and meadows.</ns3:p>
