Abstract Elevated salinity creates degrading conditions for the development of aquatic biota in different regions world. There is a need research on freshwater salinisation order to understand how this stressor alters ecosystem function and predict changes biodiversity globally. Such data are missing from Central Europe, therefore, presented study was performed inland anthropogenic ponds with levels located second largest European hard coal basin. The researcher indicated positive correlation between water biomass density macrozoobenthos as well percentage shredders abundance alien species, whereas there decrease taxa diversity richness filtering gathering collectors predators along increasing salinity. survey showed that high level nutrients organic matter were also significantly correlated distribution macroinvertebrate functional feeding groups. conducted confirmed mining acts strong filter shapes because it affects composition, abundance, traits benthic macroinvertebrates contributes invasion species.
