    SUMMARY. 〈list xml:id="l1" style="custom"〉1A choice chamber experiment was performed in the laboratory to quantify the selection of benthic algae as food and substrata by Nais elinguis.2Most worms actively chose filamentous algae and/or diatoms as substrata whereas unicellular or colonial chiorophycean algae were discriminated against. Diatoms were selected in preference to latex beads but the worms could not discriminate between living filaments and nylon monofilaments. A thigmotactic response to filaments and a chemotactic response to diatoms may be implicated.3The worms ingested unicellular algae at a greater rate than colonial and filamentous algae. The rates at which the algae were ingested were negatively correlated with the lengths of the algae. A filament 200 μm long was the largest item ingested, representing about 63% of the length of the pharynx of the worm.4Ivlev's electlvity indices were positive when the rates at which the algae were ingested exceeded about 20 individuals h-1. The index was negatively correlated with the lengths of the algae, but the time periods spent by the worms in association with the algae were unrelated to the electivity index.5The data confirmed previous observations on the selection of algae as food and substrata by Nais elinguis in a natural habitat.

    Summary Nais elinguis was offered equal densities of three algal species under controlled conditions. Colonies of Scenedesmus quadricauda were ingested at significantly lower rates than cell of Nitzschia kutzingiana and Chlorella vulgaris. Labelled cells of N. kutzingiana were more rapidly and more efficiently assimilated than those of the other algae. Cells of S. quadricauda were viable in the faeces. This work confirmed conclusions from other studies with respect to the role of algae in the nutrition of Nais elinguis and other freshwater benthic herbivores.

    Abstract The gut contents ofNais elinguis in an organically polluted river were dominated by epilithic chlorophycean unicells and pennate diatoms with an average cell volume of 1.3 × 103 µm3. The worm unselectively and opportunistically ingested unicellular algae up to a maximum length of 196 µm and a maximum volume of 24 × 103 µm3, but colonial and filamentous algae were discriminated against. The morphometry of the pharynx ofN. elinguis probably determined the maximum size of algal cells which could be ingested.
