Abstract
The gut residence time of Daphnia pulicaria feeding on three different concentrations of Cryptomonas erosa was measured by observing the passage of small plastic beads through the intestine. Passage times ranged from 4 to 106 min (mean, 27 min), they decreased with increasing food concentration, and were negatively correlated with rates of mandible movement.This publication has 2 references indexed in Scilit:
