Changes in clonal composition of Daphnia taxa in Římov and Vír reservoirs at each of the three sampling stations (dam, middle and upper). Distribution of the most common clones (i.e. frequency > 10% in at least one sample) is shown. Remaining clones were pooled and classified as "rare" (white area, up to 100%). NA indicates dates when Daphnia were no longer present at the sampling site. A blank square across the graph indicates a date when there were too few individuals of the species available to calculate clone frequencies (n = 4).
