“…This means that the proportion of inshore retention areas in the main arm was high and the lateral connection between the floodplain and main arm was strong (WARD et al, 1999). At medium water levels the current in the parapotamal side arms was not strong enough to depress rotifer reproduction, but it was sufficient to maintain an intermediate disturbance, which led to more diverse assemblages (SCHÖLL, 2009). There was a positive correlation in the parapotamal between the evenness (E) of rotifer assemblages and the water level, which determined the velocity of flow.…”

The Gemenc floodplain of the Danube possesses numerous side arms and backwaters. The aim of my study was to explore connections between hydrological events and diversity patterns of the planktonic rotifer assemblages of these water bodies. During the study period (2002)(2003)(2004)(2005)(2006)(2007)(2008) 75 taxa of rotifers were found. Generally, the water bodies of the floodplain had more diverse rotifer assemblages than the main arm. At low and medium water levels diversity was highest in the parapotamal water bodies. This result may be explained by the intermediate disturbance hypothesis. At high water levels the highest biodiversities shifted to the plesiopotamal. Biodiversity, dominance, and evenness correlated with water flow and temperature. Patterns of biodiversity seem to be determined by the water level of the main arm; therefore the water regime appears to provide pronounced temporal variability in the hydro-ecology of the floodplain.

“…Most of these parameters are defined by the overall discharge of the main arm, which varies over time (LAIR, 2005). Several studies have focused on zooplankton density and diversity patterns and their regulation by abiotic and biotic factors in large rivers, but knowledge about the role of the hydrological regime in this process on natural floodplains is limited (SCHÖLL, 2009;ELOSEGI et al, 2010). Rising and falling water levels during a flood event influence the proportion of slow-moving or still water habitat, which is necessary for formation of lotic zooplankton assemblages (SCHIEMER et al, 2001).…”

We studied the structure and population dynamics of zooplankton assemblages in the water bodies (eu-, para-, plesiopotamal and conjunctive water bodies) of a temperate floodplain during flood events. Here we report differences in the species composition of these water bodies in the two stages of flood pulses: rising vs. receding. During the receding period the proportion of larger and tychoplanktonic species increased. Similarity among zooplankton assemblages of these floodplain water bodies increased during the rising and decreased during the receding period. Species richness, diversity and population density values of zooplankton assemblages increased during the receding period in all types of water bodies except the eupotamal. The guild ratio of rotifer assemblages showed characteristic, but somewhat ambiguous changes. We conclude that the hydrological regime affects the structure and dynamics of zooplankton assemblages on the floodplain. IntroductionSpatial and temporal variability induces high productivity and biodiversity in terrestrial and aquatic components of the river-floodplain systems (SHIEL et al., 1998;ARMITAGE et al., 2003). Understanding the ecological functions of natural river-floodplain systems is important to establish criteria to protect the biota of these sites (BERCZIK and BUZETZKY, 2006). Introduction of the Flood Pulse Concept (JUNK et al., 1989) stimulated renewed interest in the connection between large rivers and their floodplains; since then numerous studies have focused on the zooplankton of large rivers. These efforts have indicated that inshore retention and hydrological connectivity are a major determinant of zooplankton assembly (HEIN et al., 1999;BARANYI et al., 2002;RECKENDORFER et al., 1999;ZIMMERMANN-TIMM et al., 2007). In contrast, most hydro-ecological research projects on large rivers and their floodplains focus just on fish and/or benthic invertebrate assemblages, thus neglecting the importance of zooplankton communities in the food-web of river-floodplain systems. Concomitantly an assessment of their suitability as a biomonitoring tool is also neglected (BORJA et al., 2008;RESH, 2008

“…No dominant species among copepods were identified due to the small number of mature individuals. Copepod larval forms (nauplii and copepodites) were the most frequent, similarly to other oxbow lakes (Spaink et al, 1998;Hein et al, 1999;Keckeis et al, 2003;Schöll, 2009). Copepods dominated over cladocerans among the crustaceans in the oxbow lakes of the lower Vistula.…”

“…Rotifer species were predominant at both sites (79% at Site 1 and 85% at Site 2). According to many authors (Keckeis et al, 2003;Pithart et al, 2007;Schöll, 2009), rotifers are the dominant group in heleoplankton. Because of their high tolerance to adverse conditions (Radwan, 2004), they are commonly found in both stagnant and flowing waters.…”

Floodplain lakes are important elements of landscapes with large rivers. In this study we compared planktonic communities of two oxbow lakes of the Vistula River. We investigated how the inflow of the river's water affected their physicochemical and biological conditions including water temperature, water transparency, oxygen concentration, and macrophyte coverage of the bottom. These parameters in turn affected plankton community. The average phytoplankton abundance in the isolated lake was over two times lower than in the lake connected to the river. Cryptophyta dominated in the phytoplankton community in the isolated lake and diatoms -in the lake supplied with water from the river. The average abundance of zooplankton in the isolated lake was more than twice as high as that in the lake which was connected to the river. The first lake proved to be more attractive for zooplankton due to its stable living conditions (similar to the conditions observed in ponds), higher temperature in summer, and nutrient availability due to the high abundance of small phytoplankton. The results of our research indicate that species composition, plankton abundance, and Chl-a concentration depended on whether there was water exchange between the particular lake and the Vistula River. Hydrological conditions shaped the relationships between the components of the biota.
