Functional response and particle size selection of Halteria cf. grandinella, a common freshwater oligotrichous ciliate.

Original language description

In laboratory experiments, we studied the growth and feeding characteristics of Halteria cf. grandinella, a common oligotrichous ciliate in freshwater plankton. Particle size dependent feeding rates were measured with fluorescent latex micropheres and natural food organisms (bacteria, Synechococcus, Chlorella). Maximum clearance rates were obtained with 2.76 m latex beads. Clearance rates declined for smaller and larger particle sizes and natural prey items. The physiological state of the ciliates did not seem to have an impact on the relative pattern of the particle size dependent functional response curves, but the absolute feeding rates decreased nearly 10-fold after prolonged starvation. The experiments demonstrated that this small filter-feeding ciliate is an omnivorous species, which is able to efficiently exploit the planktonic prey size spectrum from 0.5 to 5 m, covering heterotrophic and autotrophic pico- and nanoplankton in the diet.
