MF25022Environmental drivers shaping mayfly assemblages in a Ramsar-declared Danube floodplain




Floodplains play an important role in regulating regional water and nutrient cycles in riverscapes, also supporting high biodiversity. Owing to limited knowledge about aquatic insects’ ecological requirements in such habitats, mayfly assemblages were studied in anthropogenically disturbed and near natural habitats in a Danube floodplain. The species-poor assemblages were influenced by water quality and aquatic macrophyte assemblages. Our results confirmed the high value of habitat heterogeneity for the aquatic macroinvertebrate conservation in extreme habitats such as large river floodplains.
