Fuctional 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 and widespread oligotrichous ciliate in freshwater plankton. Particle-size-dependent feeding rates were measured with fluorescent latex micropheres (0.22 to 4.23 mu m diameter) and natural food organisms (bacteria, Synechococcus sp., Chlorella minutissima) in short-term feeding experiments. N. cf. grandinella ingested all but the smallest (0.22 mu m) particles offered and demonstrated a concentration dependent type-2 functional response. Maximum clearance rates were obtained with 2.76 mu m latex beads (0.6 mu l h(-1)). Clearance rates declined for smaller and larger particle sizes but even with the suboptimal size classes, 0.47 and 1 mu m,high maximal ingestion rates were measured (19 and 13 beads ciliate(-1) min(-1), respectively). The maximum clearance rates for bacteria and algae were close to those of similar sized latex beads, and no discrimination of particles based
