“…In this study, NO3-N, NO2-N, NH4-N and SRP, which are sources of nitrogen and phosphorus, were generally found at low concentrations in KDL (Table 1). The data is compatible with a previous study on the physicochemical properties of KDL water (Gökçe and Turhan, 2014). Among the studied parameters, NO3-N concentration was determined higher in the spring season than in other seasons (Table 1).…”

In this study, the zooplankton community and its relationship with environmental factors were investigated in the Karakaya Dam Lake (KDL). The physico-chemical characterization showed that there were obvious changes in the water quality and zooplankton population structure, which was mainly due to the organic matter source. Reactive phosphate (SRP) and nitrogen values were found in low concentrations. A total of 22 zooplankton taxa were determined, including 14 taxa of Rotifera, followed by 6 taxa of Cladocera and 2 taxa of Copepoda. The most abundant species were Synchaeta oblonga (Rotifera), Bosminia longirostris (Cladocera), and Cyclops scutifer (Copepoda). The abundance of zooplankton was highest in spring. Canonical correspondence analysis (CCA) was used to examine relationships between measured environmental variables and zooplankton composition. According to CCA, dissolved oxygen, and SRP values, there was a significant relation to zooplankton abundant with these factors. The triplots diagram demonstrated variations of the structure of zooplankton population composition which can be explained by the environmental variables. Oxidative stress (catalase, glutathione S-transferase, glutathione reductase) and neurotoxicity (acetyl cholinesterase) biomarkers were analyzed in copepod species. Glutathione reductase and acetyl cholinesterase activities were significantly inhibited in the summer. Catalase activity was induced in the spring. The seasonal changes of biomarker indicated that the KDL may be at risk of pollution that originated from agricultural and industrial activities.

“…Zooplanktonic organisms, which are significant for inland fishery, with some species, are evaluated as indicators of contamination with their sensitivity to environmental changes and forming the great part of the aquatic organisms [11]. Zooplankton species are showed as bioindicator for determining the environmental contamination occurred due to environmental parameters [12,13]. Among zooplanktonic organisms, Rotifera is the primary vertebrate group of freshwater.…”

In freshwater ecosystems, zooplanktons provide an important food source for larval fish. Some species of zooplanktons are usually considered as useful indicators of water quality and trophic state, for example, Filinia longiseta, Keratella cochlearis, Keratella quadrata, Brachionus angularis, etc. The purpose of this study is to describe the recent zooplankton composition and monthly variations, to compare results with earlier studies, to determine the trophic level of the eutrophic lake and to show eutrophic lakes in Turkey.

“…It is widely accepted that species diversity and richness decrease in an aquatic community under stress conditions, such as heavy metals, extreme organic pollution, or a sharp change in any environmental factors, but some tolerant species broke out (Xu et al, 2005). The responses of zooplankton community along a spatial gradient of trophic level can be used for environmental monitoring (Gökçe and Özhan Turhan, 2014;Schindler, 1987). In this study, the differences of zooplankton community structure directly reflected the water quality of each sampling station.…”

Abstract. To collect information about the community structure of zooplankton and to study how zooplankton respond to environmental conditions, zooplankton samples were collected from seven stations in a heavily polluted river (the Nanfei River, China). Samples were collected in March (spring) and June (summer) 2014, September (autumn) and December (winter) 2013. A total of 275 species of zooplankton belonging to 79 genera were identified, the total zooplankton abundance was 193 040 ind./L. Protozoa and rotifer comprised a high proportion of species number and abundance of zooplankton. The upper reaches had higher greater species number and lower abundance than those in middle and lower reaches, and at the entrance of Chaohu Lake. The species number and abundance of zooplankton were the highest in autumn, and the lowest in winter. The habitats of Nanfei River had high spatiotemporal heterogeneity, revealed by unweighted pair-group method using arithmetic averages (UPGMA) clustering analyses on environmental factors and detrended correspondence analysis (DCA) clustering analyses on zooplankton abundance. In addition, water quality of upper reaches was better than the middle and lower reaches, and the entrance; and better in autumn than in other three seasons in terms of species number, abundance, Shannon-Wiener index, and Pielou evenness index. Results of canonical correspondence analysis (CCA) indicate that the combination of water temperature, total phosphorus, total nitrogen, pH, chemical oxygen demanded, soluble phosphate, and conductance rate were responsible for the variations in zooplankton community structure. Results of the present study indicated that zooplankton communities of the Nanfei River had obvious spatial and temporal heterogeneity, and the environmental factors played an important role in the changes in zooplankton community in Nanfei River.
