DOI: 10.1051/kmae/2014038 The disturbance-driven changes of periphytic algal communities in a Danubian floodplain lake

Key-words: periphyton, algae, artificial substrata, disturbance, floodplain Disturbance event-driven changes in periphytic algal communities were studied in a Danubian floodplain using artificial substrata (glass slides). The hydrological regime of the river-floodplain system strongly influenced the physical and chemical environment of the investigated lake. Direc-tional changes in the algal communities, demonstrated by the results of non-metric multidimensional scaling, indicated three distinct phases in periphyton development. Strong seasonal influences in the initial accrua
