“…Furthermore, eutrophication can also lead to the dominance of Cyclopoid copepods in several reservoirs (Jeppesen et al, 2000) as a result of their feeding habits (Soto & Hurlbert, 1991;Hansson et al, 2007). In addition to the ability to consume algae (Tõnno et al, 2016) and other zooplankton (Andrade & López, 2005) through their ambush feeding habit, cyclopoid copepods show better performance in food activity under low light availability (Kandathil Radhakrishnan et al, 2020). This may explain the success of cyclopoid copepods in coexisting with cyanobacterial blooms, which commonly reduce the penetration of light into the water column.…”

Aim To test the hypothesis that zooplankton changes the structure of phytoplankton in tropical reservoirs by reducing the biomass of algal species susceptible to herbivory. Methods We experimentally evaluated the species-specific responses of phytoplankton to zooplankton within eutrophic reservoirs with different phytoplankton community structure in northeastern of Brazil. Water samples were collected from the subsurface in coastal regions of the Apipucos and Mundaú reservoirs in January/2012 and November/2014, respectively, and transported to the laboratory. The experiments were performed in Erlenmeyer flasks (1 liter) filled with water from the sample sites and were maintained for five days in the laboratory conditions. Two treatments were maintained (1) with phytoplankton and the presence of the native zooplankton and (2) without native zooplankton. Results Zooplankton proved to be an important factor, modifying the structure of the phytoplankton community, especially in the Apipucos reservoir. In this reservoir, we observed a significant reduction of biomass in diatom Cyclotella meneghiniana, and the chlorophyte Chlamydomonas sp., and an increase in the biomass of Raphidiopsis raciborskii. In the Mundaú reservoir, we observed a significant reduction of C. meneghiniana and R. raciborskii, while cyanobacteria Microcystis aeruginosa increased their biomasses in the presence of zooplankton. Conclusions These results show the importance of the microalgae community structure in phytoplankton-zooplankton interactions for food webs in tropical environments, as well as support the role of zooplankton in fostering cyanobacterial growth and maintain algal blooms.

“…for biological control of mosquito populations (Marten & Reid, 2007). In general, aquatic predators such as cyclopoids rely on a complex series of mechanisms, both sensory and locomotory, to detect prey organisms and overcome their ability to elude capture by executing evasive movements (Kerfoot, 1978;Andrade & López, 2005). The effect of epibiotic ciliates on the mechanisms for detection and capture of prey by cyclopoids has not been investigated.…”

The colonial peritrich ciliate Epistylis anastatica (Linnaeus, 1767) was discovered living as an epibiont on Mesocyclops isabellae Dussart & Fernando, 1988 collected from a pond in Andhra Pradesh state, India. This is the first report of Epistylis on this host, and a description of its morphological characteristics is provided. The biomass of colonies of E. anastatica relative to that of their hosts was relatively high, being greater than that of the host in some cases (8.11 mm³ vs. 1.14 mm³ or less), and this epibiotic burden has the potential to have an impact on the host's activities. Relationships between epibiotic peritrichs and microcrustaceans like cyclopoid copepods may be much more complex than previously supposed and merit more thorough investigation. Species of Epistylis are commonly found on cyclopoid copepods, but resources for taxonomic identification are limited and scattered; therefore, an annotated checklist of all species reported from cyclopoid copepods and a summary of the diagnostic characteristics of each one is provided as an aid to investigators. Some records of Epistylis spp. from cyclopoid copepods that are accompanied by documentary evidence are misidentifications, raising the suspicion that many other undocumented records also may be erroneous; therefore, it is suggested that authors provide supplementary descriptions and figures.
