Rotifer Communities

AbstractPeat bogs play key roles in preserving the stability of ecological relationships, but are some of the fastest disappearing and most endangered ecosystems in Europe. The aims of this study were: (1) to compare the distribution, species richness, diversity, and density of rotifers in microhabitats of a raised bog; and (2) to verify the hypothesis that rotifer density and species composition are dependent on seasonal factors, moss moisture content, and the dominant species of mosses in the microhabitats. Sampling was done monthly from April to November in 2013–2014 in the bog Moszne in eastern Poland (51°27′28.7″ N, 23°07′15.8″ E). The microhabitats sampled included hummocks, slopes, and hollows. A total of 40 rotifer taxa were identified. The highest species richness occurred in the hollows (40), dominated by

AbstractThe rotifer community structure may be shaped by a variety of environmental factors, including biological parameters, such as predation or competition, as well as by physical-chemical factors, among which the kind of macrophyte substratum and parameters relating to the trophic state and to the catchment area conditions are of great importance. Another impact on rotifer composition, abundance and frequency may be expected when considering differentiated macrophyte types (including helophytes, nymphaeids and elodeids) within a group of eight ponds located within a mid-forest catchment area, which was the main aim of the present study. Detailed analysis on the participation of indicator eutrophic rotifer species provided an additional goal of this investigation in order to qualify the trophic state of this kind of water body located within the Wielkopolska region, in the central western part of Poland.The presence of 117 taxa, including 7 species that are rare or infrequently distributed in the Polish fauna was recorded. The number of taxa and rotifer abundance differed greatly in respect to the specific water body and to the type of substratum. The vegetated zones dominated by elodeids were characterised by the most various and most abundant rotifer communities as well as by the highest values of the Shannon-Weaver index. This reflects a positive relationship between the heterogeneity of habitat and the structure of rotifer communities. It was also found that helophytes and the open water zone possessed the highest, while elodeids the lowest percentage of eutrophic species.

Rotifer Communities

The rotifer communities of eight religious water bodies of Haryana characterized by different trophic status reveal 44 species belonging to 15 genera and 12 families, represent the richest biodiversity of rotifers. Brachionus, Asplanchna and Keratella genus were found to be pollution tolerant species and common at all the selected water bodies viz., Brahmsarovar and Jyotisar at Kurukshetra; Saraswati tirth, Pehowa; Kapalmochan, Yamunanagar; Phalgu tirth, Kaithal; Banganga tirth , Dayalpur; Pandu Pindara, Jind and Kultarn Tirth, Kirmach. whereas Gastropus, Testudinella, Monostyla clasterocerca, Lecane arcula, Filina terminalis were found to be specific at Brahmsarovar (site 1); Filinia longiseta at Phalgu (site 2); Lecane ploenensis, Euchlanis dilata at Pehowa (site 3); B. budapestinensis, B. nilsoni, Asplanchna brightwelli, Asplanchna sieboldii, Polyurthera were specific to Kirmach (site 4); Monostyla decipiens, Anauraepsis nevicula at Jyotisar (site 5); Trichocera porcellus at Kapal mochan (site 7); Keratella cochlearis, Trichocera capucina were found to be specific at the BanGanga (site 8,). However, no specific species appeared at Pandu Pindara (site 6). Seasonal variations were also observed at all the sites during spring, monsoon, post monsoon and in winters. A positive correlation of rotifer abundance was observed with temperature (r = 0.356, P < 0.05), BOD (r = 0.413, P < 0.05) and Ammonia (r = 0.378, P < 0.05) whereas a negative correlation was observed with DO (r = -0.385, P < 0.05) showing that these were the main factors affecting the richness, diversity and density of rotifers. The rotifer communities of each site can be reconstructed from the tables and figures making this inventory an important benchmark for evaluating future regional environment change.
