“…The importance of rotifers increases in comparison to cladocerans when the abundance of the latter is low [38] Furthermore, rotifers are known as an opportunistic species in extreme conditions [39]. Within the last decade, because of the degradation of water quality of many wetlands for a variety of reasons (pollution, eutrophication, etc., and the effect of global warming), rotifers have become dominant species in many aquatic habitats [40]. In line with that finding, this study identified that most of the zooplankton species belonged to phylum Rotifera.…”

The zooplankton and its seasonal distribution of Sevsak Stream has been investigated in 2021. A total of 31 zooplankton species have been recorded in the stream. Among the zooplankton, 19 species belong to Rotifer,9 species to Cladocera and 3 species to Copepoda. In every season, zooplankton species were recorded in various abundance. Highest number of taxa was recorded in spring. In this season also, an increase occurred in the individual numbers of species. Keratella cochlearis, Polyarthra dolichoptera and Cyclops vicinus were the most recorded species in the stream. As in the other aquatic habitat, rotifera group was determined as the most recorded species in terms of taxa and number of individuals.

The present study describes the abundance and biomass distribution of gelatinous macrozooplankton in relation to physical parameters in Hamsilos Bay. Gelatinous macrozooplankton samples were collected monthly from four stations between July 2015 and June 2016 using a plankton net with a 112 μm mesh size and a 50 cm diameter mouth opening by vertical hauls. Four gelatinous macrozooplankton species were identified: Aurelia aurita (Linnaeus, 1758); Mnemiopsis leidyi A. Agassiz, 1865; Beroe ovata Bruguière, 1789; and, Pleurobrachia pileus (O.F. Müller, 1776). The maximum mean abundance of gelatinous macrozooplankton was recorded in August 2015 (24.58 ind. m-2), whereas the maximum mean biomass was recorded in April 2016 (147.79 g m-2) from four sampling stations. The abundance and biomass of gelatinous macrozooplankton increased in the summer and spring. M. leidyi and P. pileus were primarily responsible for the increase in total gelatinous macrozooplankton abundance in the summer, whereas A. aurita and B. ovata were primarily responsible for the increase in total abundance in the spring and autumn. The abundance and biomass of M. leidyi were positively correlated with temperature and negatively correlated with dissolved oxygen.

“…ultimately resulting in mortal damage being inflicted on the cladoceran. As of this writing we are aware of > 12 papers that have cited this paper, but most only reference it without commenting on its findings (e.g., Santos-Wisniewski et al, 2011;Jaramillo-Londoño & Aguirre-Ramírez, 2012;Pauwels et al, 2014;Kotov & Fuentes-Reines, 2015;Ergönül et al, 2016;Gürbüzer et al, 2017). Because observation regarding Hexarthra impacting Bosmina influences our understanding of the freshwater food web, in general, and specifically the niche and trophic dynamics of rotifers, we believe that the methods and conclusions of this paper need to be re-examined carefully.…”

Evidence does not support the conclusion that Hexarthra intermedia (Rotifera, Monogononta, Flosculariaceae) causes mortality in Bosmina longirostris (Cladocera, Diplostraca, Branchiopoda)

Evidence does not support the conclusion that Hexarthra intermedia (Rotifera, Monogononta, Flosculariaceae) causes mortality in Bosmina longirostris (Cladocera, Diplostraca, Branchiopoda)Based on observations of preserved samples, Jaramillo-Londoño & Pinto-Coelho (2010) describe a putative ecological relationship between the rotifer Hexarthra intermedia and the cladoceran Bosmina longirostris as a fusion of parasitism and interference competition. They argue that H. intermedia enter the filtering chamber of B. longirostris allowing the rotifer to exploit food collected by Bosmina, while simultaneously receiving protection from predators. In addition, they surmise that the result of this interaction can lead to death of Bosmina. We posit two simpler explanations for their observations. (1) Presence of H. intermedia in the cladoceran's filtering chamber is an artifact of the collection methods. (2) Statistical correlations between the population levels of these two species simply means that the environment was suitable for their growth. Thus until additional evidence corroborates their findings, the simpler explanations should prevail.
