"With increasing trophic status, a higher portion of bacterial production was consumed by ciliates, accounting for 40 and 50 of the total protistan bacterivory in dam reservoirs. Increases were attributable to the oligotrichs of the genus Halteria that often numerically dominate freshwater pelagic ciliate communities. The most important ciliate bacterivores in order of their decreasing importance were: oligotrichs (primarily Halteria spp.), peritrichs, and scuticociliates. Our results suggest that small halteriids are ecologically important bacterial consumers in meso to eutrophic freshwater systems due to: (i) an efficient uptake of prey over a large size spectrum, (ii) high clearance rates on picoplankton-sized particles, (iii) high potential growth rate, and (iv) a low vulnerability to metazooplankton predation. Correspondingly, we suggest a revised concept of planktonic ciliate bacterivory, where the principal role is attributed to small omnivorous filter-feeding oligotrichous ciliates." .
