This paper summarizes preliminary results of the study focused on geological characteristics, dating and pal
aeoecological analysis of sedimentary infill of the former Dudváh River palaeomeander. Study area is located in central part of the Žitný ostrov Island, SW Slovakia, near the village Štúrová. 
Pollen analysis has been carried on a 100 cm thick sediment profile from paleomeander Štúrová. Analyses of 22 samples characterise the development of the water and terrestrial biotope and the surrounding landscape the last ca 2000 – 2500 years. Pollen transported from longer distances was significant due to the openness of the landscape, coming from northern part of Slovakia mountains. A high degree of afforestation (Abies, Fagus, Picea, woods of alluvial forests) was characteristic for the Younger Subatlantic 
(X). During Subatlantic period, pollen of synanthropic plants appears. Phases of the aquatic and w
etland biotope development were defined on the first (DV-SK1) and second (DV-SK2) zones on the basis of coccal green algae and aquatic and wetland plant ecosystems (Myriophyllum, Trapa natans, Potamogeton). The palynological research was supported by the grants (research program) MZP000257801 (Czech Republic) and VEGA 2/5016/25 and 2/5014/25 (Slovakia).
