Impact of invertebrate predators on rotifer populations in lakes: field observation and experimental analysis

Rotifer communities under variable predation-turbulence combinations

“…Differences in the average individual length of rotifers were analyzed with ANOVA (all taxa combined and different taxa separately). Additionally, as rotifer abundance often increases with increasing chlorophyll a concentration via increasing food abundance (Nagata et al, 2006), the variations in chlorophyll a concentration were analyzed with ANOVAR.…”

“…Due to their high abundance in some ecosystems, rotifer community grazing rates may match, or even exceed those of some crustaceans both on a daily and annual basis (Bogdan & Gilbert, 1982). Additionally, rotifers form a substantial food source for many planktivorous organisms, including cladocerans, copepods, chaoborids, and fish larvae (Williamson, 1983;Moore & Gilbert, 1987;Nagata et al, 2006). Therefore, any disturbance affecting rotifer communities may influence the whole aquatic food web, and turbulence levels in many aquatic ecosystems are probably increasing due to increasing wind speeds and decreasing water levels, and these changes will influence the planktonic communities (Pryor et al, 2005;G.-Tóth et al, 2011).…”

Potential impact of underwater released exhaust gas from innovative ships on the marine ecosystem

“…Microalgae and rotifers are popular model organisms for microscale aquatic toxicity tests due to their high sensitivity and cost-efficiency (Bautista-Chamizo et al, 2019;Seoane et al, 2017;P G Wells et al, 1997). Both groups are ecologically important as food source for other aquatic organisms, such as copepods and fish larvae, effects could thus influence the entire food web (Nagata et al, 2006;P G Wells et al, 1997).…”
