Abstract:The abundance and the biodiversity of summer zooplankton in the waters of the Drawa drainage (NW Poland) were studied, as was their relation to selected environmental conditions. The conditions upstream, especially in the outlets of lakes, did not affect the zooplankton communities downstream. This was also true of tributaries which had no influence on the shape of the zooplankton communities in the main river. The number of zooplankton in the outlets of eutrophic lakes was greater than in those of mesotrophic lakes. Increased vegetation cover significantly affected mainly the crustacean communities of zooplankton. Larger amounts of zooplankton were observed in rivers where the riparian zone was not covered with vegetation, but this difference was not significant. The hydrological conditions of the rivers and the Secchi depth visibility strongly impacted the composition of the zooplankton. The influence of abiotic factors was most pronounced on the abundance of cladocerans, and least pronounced on the abundance of rotifers.

Diversity and abundance of zooplankton in relation to nitrate-N and total phosphorus levels of 20 minor and medium scale reservoirs in the low country intermediate zone of Sri Lanka were studied in June-October 2013. Total phosphorus content ranged from 0.029 mg L -1 recorded in Wendaruwewa reservoir to 0.529 mg L -1 recorded in Karangamuwa reservoir and Nitrate-N content varied from 1.186 mg L -1 recorded in Adukkane reservoir to 5.625 mg L -1 recorded in Anukkane reservoir indicating that all reservoirs studied are eutrophic. During the present study, a total of 43 species of zooplankton, comprising 31 species of rotifers, 9 species of cladocerans and 3 species of copepods were recorded. Number of zooplankton species in any one reservoir, which ranged from 4 to 13, was significantly correlated with the nitrate-N content (p<0.05). The most widely distributed zooplankton species was Diacyclops nanus, which was present in 15 reservoirs. Abundance of zooplankton ranged from 4 individuals L -1 recorded for Alona monocantha and Chydorus parvus in Wendaruwewa and Metiyagane reservoirs respectively to 1017 individuals L -1 recorded for Filinia terminalis in Galewela reservoir. Margalef index which ranged from 0.532 in Adukkane reservoir to 2.096 in Dewahuwa reservoir, was significantly correlated with nitrate-N content of water (p<0.05). Pielou index ranging from 0.65 in Galewela reservoir to 0.92 in Polpitiya reservoir and Shannon-Weiner index ranging from 0.91 in Munamaldeniya reservoir to 2.13 in Dewahuwa reservoir were not significantly correlated with nitrate-N and total phosphorus levels of water (p>0.05). Keratella quadrata was present only in Anukkane reservoir where the nitrate-N content was the highest and therefore it may be considered as a bio-indicator of high levels of nitrate-N. Eutrophic conditions of theses reservoirs may possibly be due to runoff of nutrients from agricultural fields as these are located in an intense agricultural area. Therefore, it is necessary to take immediate action to control the overuse of inorganic fertilizer in this area so that contamination of water bodies with nutrients can be minimized.

“…The presence of zooplankton in small rivers depends on the character of the catchment area. Zooplankton appears in rivers as a result of being carried from lakes, slack water or floodplains or from tributaries containing drifting zooplankton (Szlauer, 1977;Ejsmont-Karabin & Węgleńska, 1996;Marneffe et al, 1998;Akopian et al, 1999;Pithart et al, 2007). Analyses of the zooplankton of sections of small rivers with no tributaries and reservoirs in their course have shown that the qualitative composition and quantity decrease with increasing distance from the river outflow from the lake.…”

Similarities in zooplankton community between River Drawa and its two tributaries (Polish part of River Odra)

Zooplankton communities were studied in a river and its tributaries with different hydrological, biological and physico-chemical conditions. Small similarities were noted in the zooplankton community (mostly Rotifera) between a tributary characterised by a regular bed and the river. No influence of a tributary with an irregular bed and variable water flow was noted on the zooplankton of the river it joined. It was concluded that the tributaries had very little influence on the zooplankton community in the river which they joined. The most probable reasons for this were the predatory behaviour of fry, escape of zooplankton into the river vegetation and therefore not carried down by the river current, and reproduction of zooplankton in slack waters, small floodplains and densely vegetated riparian zones of the main river.
