Diversity of Periphytic Chironomidae on Different Substrate Types in a Floodplain Aquatic Ecosystem

Different types of water bodies in lowland river floodplains represent vital biodiversity havens and encompass diverse microhabitats, which are essential for structuring different macroinvertebrate communities. Chironomidae larvae (Diptera) an inseparable part these communities, with their high richness abundance. In three body within the Danube floodplain Kopa?ki Rit Croatia, over course four sampling campaigns, we recorded 51 chironomid taxa periphyton on macrophytes, twigs, glass slides. The most were communities whilst month-old twigs supported least taxa. Cricotopus gr. sylvestris, Dicrotendipes lobiger, spp., Endochironomus albipennis, Glyptotendipes pallens agg., Polypedilum sordens spp. present all studied microhabitats. type substrate is a very important factor influencing diversity abundance, was evident presence dominance Corynoneura scutellata Monopelopia tenuicalcar dense macrophyte canopy epiphyton. Finding pristine such as can be challenging, areas increasingly altered by human activities. Studies resident species extent to changes parent influence protection restoration floodplains.
