“…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.

“…Perhaps the overabundance of decomposing organic matter, as well as the effect of decomposing barley straw, causes a poor development of blue-green algae in this reservoir. This supposition for low abundance of Cyanobacteria gives Pithart et al (2007) in the small oxbow lakes of the Lužnice River.…”

“…Cryptomonads are also able to better capture nutrients because of their ability to mixotrophy (Jones 2000). Dominant Cryptophyta are common in many oxbow lakes (Paidere et al 2007;Pithart et al 2007;BovoScomparin and Train 2008;Krasznai et al 2010), which may be due to their high tolerance to different trophic conditions and resistance to shade in the water column. Cryptomonads are very sensitive to predation by zooplankton communities (Reynolds et al 2002;Reynolds 2006;Padisák et al 2009).…”

The study focused on three oxbow lakes which have been isolated from the water of the Vistula River for several years. The diversity of phytoplankton communities was observed biweekly in the growing season (April-October), both in the three floodplain lakes along the lower Vistula River (northern Poland) and in the main current of the river. The water level in the Vistula River remained low, so the lakes were not filled with the surface water of the river. Different phytoplankton communities occurred in the studied lakes compared to the Vistula River. The phytoplankton in the oxbow lakes consisted mainly of small unicellular and colonial flagellates: Cryptomonas, Chlamydomonas, Trachelomonas, and Dinobryon. During the limnophase, only 2-3 species co-dominated, and the reservoirs were in a stable water conditions. The river phytoplankton had both higher diversity and higher abundance compared to the floodplain lakes. In total, 4-8 species co-dominated in the river, usually Chlorococcales and diatoms. The floodplain lakes were characterized by unexpected differences in the quality, quantity, and dynamics of planktonic algae. The differences were strictly associated with the occurrence of macrophytes. During the limnophase, the investigated oxbow lakes were also diversified in terms of colonizing plant communities. Different types of vegetation-free floating plants (W-1 lake), communities of submerged macrophytes, free floating plants and algal mats detached from the bottom (W-2 lake), and submerged macrophytes (Ma lake), affected the development of the microflora to a varying extent.
