Popis: |
The present study reports observations on the bacterivory of a large-size euglenid flagellate (body length: 30–40 μm; average biovolume: 1.5 × 10 4 μm 3 ), tentatively identified as a species of Dinematomonas (Dinema) , upon fluorescently-labelled bacteria (FLB). Flagellate and bacterial strains were isolated from eutrophic sites of the Seto Inland Sea of Japan. The size ratio between predator and prey ranged from 12:1 to 27:1. Grazing rates ranged from 0.05 to 16.9 FLB min −1 according to experimental conditions. A significant positive linear relationship was observed between the flagellate biovolume and the grazing rate. There was no simple relationship between grazing rates and incubation temperature, and between prey concentration or viability and grazing rates. |
