The effect of food concentration on swimming patterns, feeding behavior, ingestion, assimilation, and respiration by Daphnia1

Porter, Karen G., Gerritsen, Jeroen, Orcutt, John D.·1982·Limnology and Oceanography

Abstract

Swimming patterns, feeding behaviors, and ingestion, filtering, assimilation, and respiration rates were measured for Daphnia magna in food concentrations from 0 to 10 6 Chlamydomonas reinhardi cells·cm−3, equivalent to 0–20 mg C·liter −1. A Holling type 2 functional response curve or an Ivlev model without a threshold appear to be biologically meaningful descriptions of Daphnia feeding response to different food concentrations. Daphnia has no feeding threshold or reduced filtering activity at low concentrations such as are predicted by optimal foraging models. Above the incipient limiting concentration, constant ingestion rates and an over‐collection of food result in increased rejection rates. These behaviors may cause high respiratory rates and reduced net assimilation rates at the highest food concentration. Daphnia does not orient to or alter swimming patterns in response to algal patches.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
