Sažetak
Most research on zooplankton communities has focused primarily on the growing season, and their changes during the winter period have been poorly studied. The objective of this study was to examine changes in zooplankton and diatom communities during winter in an alluvial floodplain. The study was conducted weekly in Lake Sakadaš and Čonakut Channel in Kopački Rit Nature Park (Croatia) during winter 2019. Samples were taken for zooplankton and diatom communities, chlorophyl-a and water chemistry analyses. The abundance of rotifers changed significantly (one-way ANOVA F=7.3, p=0.01), with the highest abundance (328 ind/L) recorded at the end of the study when temperature increased significantly (F=24.35, p<0.001). The community was characterised by low diversity and high dominance. The predominant species were Synchaeta tremula, Polyarthra vulgaris and Brachionus calyciflorus species complex, whose co-dominance alternated. According to water chemistry analyses, the sampled sites were eutrophic to hypertrophic, but there were very few diatom species on which rotifers could feed. The environmental parameters that had a strong influence on rotifers were water temperature (r=0.67, p=0.02) and oxygen concentration (r=0.48, p=0.043). These results provide information about the dynamics of the winter plankton and show which environmental parameters are significant for the development of rotifers in winter.
