“…Moreover, abundance ratios of ciliates provide a comparatively real picture about actual trophic conditions and an intensity of self-purification processes in freshwater environments (for review, see Blatterer 2008). Water quality evaluation by ciliate taxocoenoses was and is still frequently utilized in biomonitoring studies (e.g., Šrámek-Hušek 1958;Liebmann 1962;Bick 1972;Sládeček 1973;Madoni 1983Madoni , 2005Madoni & Bassanini 1999;Madoni & Zangrossi 2005;Madoni & Braghiroli 2007). Following this approach, a number of watercourses and water reservoirs have been saprobiologically evaluated in Slovakia (e.g., Tirjaková 1993Tirjaková , 1997Tirjaková , 1998Tirjaková , 2003aTirjaková , b, 2004Tirjaková , 2006Tirjaková , 2010Baláži & Matis 2002;Tirjaková & Stloukal 2004).…”

A long-term monitoring of the upper Váh River was carried out in order to evaluate evolution of water quality by means of ciliate taxocoenoses. One sampling station (Lisková) was located upstream of the pulp and paper mill in the town of Ružomberok, while two stations (Bystrá and Stankovany) were situated downstream of Ružomberok. Benthic samples were collected three times a year at each station during 2004-2011. This long-term study enabled us to assemble a comprehensive checklist of ciliates recorded in the upper Váh, and to characterize and compare the ciliate communities in the investigated watercourse. The saprobic index and valency analysis of the ciliate communities allowed us to quantify organic input and to evaluate changes in the saprobity of the upper Váh. The saprobic index ranged from 2.45 to 3.66 corresponding to the quality classes II-IV. Further, there was a prevalence of the α-and β-mesosaprobic levels, but during some periods the polysaprobic level increased along with the decrease of the β-mesosaprobic level. Beside the organic pollution, toxic contaminations were also noticed several times in the studied watercourse. This was documented by a significant drop in the species diversity and abundance of ciliates as well as by various morphological malformations and movement disorders of ciliates and other microorganisms. However, the negative effect of toxic and/or organic pollution wore off relatively quickly, indicating a good self-purification capability of the river.

“…Unlike water quality measurements, which only provide an instantaneous assessment of lake conditions, protozoa community can be used to identity past disturbances and toxic effects that are not readily detected by chemical means (Cairns and McCormick, 1993). Many studies have focused on the significance of protozoa in biological wastewater treatment Bharati et al, 2001;Nicolau et al, 2001;Scholz et al, 2002;wang et al, 2004;Lee et al, 2004;Madoni and Zangrossi, 2005).…”

There is increasing recognition that protozoa is very useful in monitoring and evaluating water ecological healthy and quality. In order to study the relationship between structure and function of protozoan communities and water qualities, six sampling stations were set on Lake Donghu, a hypereutrophic subtropical Chinese lake. Microbial communities and protists sampling from the six stations was conducted by PFU (Polyurethane foam unit) method. Species number (S), diversity index (DI), percentage of phytomastigophra, community pollution value (CPV), community similarity and heterophy index (HI) were mensurated. The measured indicators of water quality included total phosphorus (TP), dissolved oxygen (DO), Chemical oxygen demand (COD), NH 4 + , NO 2 − and NO 3 − . Every month water samples from stations I, II, III, IV were chemically analyzed for a whole year, Among the chemically analyzed stations, station I was the most heavily polluted, station II was the next, stations III and IV had similar pollution degrees. The variable tendencies of COD, TP, NH 3 , NO 2 − , NO 3 − , and DO during the year was approximately coincident among the six stations. Analysis from the community parameters showed that the pollution of station 0 was much more serious than others, and station V was the most slight. Of the community parameters, CPV and HI were sensitive in reflecting the variables of the water quality. Community similarity index was also sensitive in dividing water qualities and the water quality status of different stations could be correctly classified by the cluster analysis. DI could reflect the tendency of water quality gradient, species number and percentage of Phytomastigophora was not obvious in indicating the water quality gradient.

“…The lentic ciliate species Phascolodon contractilis was not listed in any of the mentioned rivers, possibly because it can be confused with Phascolodon vorticella (Mažeikaitė 2003). Paruroleptus piscis, Frontonia leucas and Litonotus lamelata were recorded in the Taro River (northern Italy) by Madoni & Zangrossi (2005).…”

Species composition of plankton ciliates was studied in the Curonian Lagoon in 2007-2008 and compared to long term investigations dating back to the 1980 th . In total, 152 taxa were identified at the level of species or genera. More species (76 species/higher taxa) was found in the estuarine part of the Lagoon due to temporally unstable salinity and the presence of both freshwater and brackish/marine species. Some of the brackish/marine species: Tintinnopsis baltica, Tintinnopsis kofoidi, Cothurnia maritima, Lohmaniella oviformis, Lohmaniella spiralis and Helicostomella subulatum were recorded for the first time in the lagoon. The ciliate community at the freshwater sites was less diverse, containing 63 species/higher taxa in the central stagnant part of the Lagoon and 47 -in the Nemunas River avandelta. The comparison of present and past studies revealed that the use of a single live-counting method could lead to underestimation of small nanociliate species, whereas examination of Lugol fixed material provides relatively poor taxonomic information.
