Abstract

Springtails (Collembola) are a key group of soil mesofauna, important in decomposition of organic matter, and sensitive indicators of ecosystem’s condition. However, their communities in Arctic floodplain and technogenically disturbed habitats remain poorly studied. This work aimed to assess the functional organization of collembolan communities in the zonal, floodplain, and technogenic sites of the Bolshezemelskaya Tundra. To this end, soil sampling was conducted in the vicinity of Vorkuta. The study revealed that in the technogenic sites, the abundance of hemiedaphic and euedaphic forms decreases, whereas epiedaphic species maintain high abundance. In the floodplain sites, epiedaphic species showed the lowest abundance. The abundance of species with sexual and parthenogenetic reproduction modes is significantly lower in disturbed habitats; however, parthenogenetic species are more resistant to stress conditions. The results of principal component analysis (PCA) indicate that the main differences between communities are primarily associated with gradients of acidity and organic matter content. These data suggest that the functional organization of Collembola communities is transformed under floodplain regimes and technogenic impacts
