“…In natural waters, cladocerans usually ingest green algae and Microcystis simultaneously (Hanazato and Yasuno, 1984). As non-toxic Microcystis lacks nutrients such as essential fatty acids and sterols (Von Elert and Wolffrom, 2001;Martin-Creuzburg et al, 2008), many studies have demonstrated that non-toxic Microcystis is a poor quality food for zooplankton (Hanazato and Yasuno, 1984;Smith, 1995). The nutritional deficiency of non-toxic Microcystis in mixed food in our experiment was compensated to a certain extent by the nutrition of a higher proportion of Chlorella, but it cannot be completely compensated, as reported in some previous studies that although cladocerans ingesting a good food with a small amount of non-toxic Microcystis can maintain their survival (Huang et al, 2020;Alva-Martínez et al, 2001), they also show a significant decline in development, reproduction, and growth (Hanazato and Yasuno, 1984;Huang et al, 2020), which was consistent with the results of our experiment using a certain proportion of non-toxic Microcystis.…”

In aquatic ecosystems, cladocerans, an important part of zooplankton, are often exposed to new pollutant nanoparticles and poor quality food simultaneously. To evaluate the combined effects of poor quality food and nanoparticles on the development and early reproductive performance of cladocerans, we exposed Daphnia magna, a representative cladoceran, to different concentrations of ZnO nanoparticles under the food conditions containing different proportions of non-toxic Microcystis, recorded some key indicators of the early life history, and analyzed the possible differential dose effects. The results showed that non-toxic Microcystis and ZnO nanoparticles significantly delayed the times to maturation and reproduction and also significantly reduced the survival time, the body length at maturation, the number of offspring in the first brood, and the total offspring per female of D. magna. When the food contained non-toxic Microcystis, D. magna did not reach sexual maturity at 0.25 mg L−1 ZnO nanoparticles and did not develop eggs and reproduce offspring at 0.20 mg L−1 ZnO nanoparticles, especially non-toxic Microcystis and ZnO nanoparticles had a significant or nearly significant synergistic effect on the time to maturation, time to first brood, and the total offspring per female of D. magna, whereas for other life history indicators, non-toxic Microcystis and ZnO nanoparticles showed an additive effect, based on comparing the slopes of linear fitting of the relevant indicators with nanoparticle concentration under different food quality conditions. Such findings are helpful to realistically evaluate the comprehensive stress effect on zooplankton under the complex conditions of poor food quality and coexistence of pollutants.

“…zooplankton) are also expected to change in a warming, increasingly eutrophic world (Benndorf & Henning, 1989;Ger et al, 2014). Cyanobacteria act as a relatively poor food source for common zooplankton taxa, such as copepods (DeMott & Moxter, 1991) or various species of cladocerans (Hanazato & Yasuno, 1987;Lundstedt & Brett, 1991;Smith & Gilbert, 1995). This is commonly imputed to low nutritional value, due to a lack of poly-unsaturated fatty acids (PUFAs) and/or sterols (DeMott & Müller-Navarra 1997;Ravet et al, 2003), in addition to their toxicity .…”

Prior exposure of a fungal parasite to cyanobacterial extracts does not impair infection of its Daphnia host

et al. 2022

Cyanobacteria periodically dominate phytoplankton composition in lakes, and produce a wide array of toxic secondary metabolites. Blooms of cyanobacteria often coincide with infections of zooplankton by microparasites (such as Metschnikowia bicuspidata, a parasitic yeast of Daphnia), and prior research has shown that cyanobacteria-based diets could mitigate fungal infections of the host. Here, we tested whether cyanotoxins could exert detrimental effects against free-living parasite stages: we inoculated two genotypes of the host Daphnia galeata × longispina with fungal spores, which were previously exposed to cyanobacterial extracts or to a placebo solution. Additionally, to test for interactive effects of cyanotoxins through environmental exposure and host consumption, Daphnia from each treatment were fed using either green algae or the same cyanobacterium. Exposing spores to cyanobacterial extracts did not reduce their infectivity; instead, parasite infectivity was increased, but only on one host genotype. The effect of host diet on parasite growth was also host-genotype dependent, with only one Daphnia genotype showing impaired spore production under a toxic diet. Our results suggest that dissolved cyanobacterial compounds released during blooms may not exert any detrimental effect on fungal spore banks, but likely influence transmission of the parasite when incorporated as part of the host’s diet.
