Effect of flood on the bacterioplankton community structure in the Danube river floodplain (Kopački rit, Croatia)

The aim of this investigation was to examine the development of colony-forming units of copiotrophic and oligotrophic bacteria in the Kopački Rit floodplain. The bacterioplankton community structure was examined in relation to frequent flood pulses during year 2005 on sampling stations with unequal connectivity. Because of different connectivity, a shift in community structure-change in ratio of copiotrophs and oligotrophs-was expected as the establishment of different carbon sources emerged. The structure of samples was revealed by principal component analysis of abiotic water properties and the chl-a concentration by which their dimensionality was also reduced. Scores of significant components were used in a multiple regression as independent variables and the relationship between established water properties and bacterial abundance was examined. Regression model was significant only for copiotrophic bacteria (R2=0.114, P=0.004). Their relative increase was noticed in only two samples on more isolated sampling stations suggesting the existence of a higher concentration of labile dissolved organic carbon only in these samples. The dominance of oligotrophic bacteria was pronounced during the flood pulses or drainage after it. Samples in which elevated abundance of oligotrophs occurred were equally distributed in all groups of samples revealed by principal component analysis. Such results suggest their allochthonous origin. During raising water level oligotrophs probably emerge from the perturbed sediment while during drainage they are washed out from the surrounding lowland area of the floodplain. At the same time copiotrophs are to some extent coupled with established water properties i. e. bottom-up controlled.
