“…Similarly, in North Island of New Zealand (temperate zone), rotifer assembly was most strongly associated with WT and trophic indices (Duggan et al 2002). In addition, our findings were consistent with the established results that rotifer diversity in warm temperate lakes is positively correlated with TP (Wen et al 2017;Spoljar et al 2018). Among the three climatic zones, the warm temperate zone showed the greatest variation throughout the year.…”

Comparative analyses of rotifer community structure in freshwater lakes among different climatic zones are limited. In this study, six freshwater lakes located in warm temperate, subtropical and tropical zones were selected to investigate the annual dynamics of rotifer communities and their major driving factors. The results indicated that rotifer community structure did not exhibit significant seasonal variations. However, significant differences were observed among climatic zones. The species number and total density of rotifers were significantly higher in subtropical lakes than in lakes from other zones (p < .05). Both multidimensional scaling and detrended correspondence analysis revealed significant separation of tropical samplings from warm temperate and subtropical samplings, which was mainly caused by the higher temperature and lower chlorophyll a content in the tropical lakes. Further analyses indicated that rotifer community structure was mainly affected by water temperature, trophic indices and pH in the warm temperate zone but by chlorophyll a content and Secchi depth in subtropical lakes. In addition, only the Simpson index was significantly associated with Secchi depth and pH in tropical lakes. Overall, these results indicated great differences in annual dynamics of rotifer communities and their driving factors among warm temperate, subtropical and tropical zones.

“…Perhaps, in habitats easily available to both cladocerans and small fish, this refuge becomes a trap. This kind of ''the refuge effect'' has been already observed for macrophytes, which become risky areas for zooplankton due to presence of littoral predators (Sagrario et al, 2009;Š poljar et al, 2018).…”

Mollusks represent one of the most important components of freshwater zoobenthos and their shells provide a substrate for many organisms creating epibiotic communities of predominantly facultative nature. We determined rotifer species that colonize shells of Dreissena polymorpha (Pallas, 1771) without and with presence of large Cladocera and fish, alone and together. The experiment was conducted in 12 mesocosms filled with water from the littoral zone of a eutrophic lake. The experiment involved four treatments (three replicates each): (1) control of D. polymorpha in lake water; (2) D. polymorpha in lake water with the addition of large Cladocera; (3) D. polymorpha in lake water with the addition of fish; and (4) D. polymorpha in lake water with the addition of large Cladocera plus fish. The study revealed that epizoic rotifer fauna found on D. polymorpha is relatively abundant and rich in species, different from plankton communities in the same mesocosms, and specific, that is, include species that prefer this habitat. It may also suggest that communities of epizoic rotifers are impacted by the presences of benthic predators, as well as by small fish and large crustaceans inhabiting littoral waters.

“…Comprehensive studies of rotifer distributions are common, but vary widely in their focus. For example, many emphasize long-term, ecological questions across several water bodies [125][126][127][128], the dynamics in a particular lake [129][130][131][132][133][134] or region [13,14,117,[135][136][137][138][139][140], or examine a single taxon [141][142][143][144][145][146][147][148]. Collectively, such studies provide insight into the biogeography of the phylum.…”

Desert aquatic systems are widely separated, lack hydrologic connections, and are subject to drought. However, they provide unique settings to investigate distributional patterns of micrometazoans, including rotifers. Thus, to understand rotifer biodiversity we sampled 236 sites across an array of habitats including rock pools, springs, tanks, flowing waters, playas, lakes, and reservoirs in the Chihuahuan Desert of the USA (n = 202) and Mexico (n = 34) over a period of >20 years. This allowed us to calculate diversity indices and examine geographic patterns in rotifer community composition. Of ~1850 recognized rotifer species, we recorded 246 taxa (~13%), with greatest diversity in springs (n = 175), lakes (n = 112), and rock pools (n = 72). Sampling effort was positively related to observed richness in springs, lakes, rivers, and tanks. Nestedness analyses indicated that rotifers in these sites, and most subsets thereof, were highly nested (support from 4 null models). Distance was positively correlated with species composition dissimilarity on small spatial scales. We predicted species richness for unsampled locations using empirical Bayesian kriging. These findings provide a better understanding of regional rotifer diversity in aridlands and provide information on potential biodiversity hotspots for aquatic scientists and resource managers.
