Fig. 4: Results in environments with food patches of different bacterial species.
From: Caenorhabditis elegans foraging patterns follow a simple rule of thumb
a Schematic of the experimental set-up: We placed 5 food patches of different densities and different bacterial species, and counted the number of worms per patch after 2 h. b Relative number of worms found at each food patch, as a function of effective density (\({D/D}_{{attract}}\)). Black line: Sigmoid with \(H=146\), \(k=1.4\). c Measured proportion of worms in each food patch, versus proportion predicted by the sigmoid using effective density and the same parameters as in box b. See Supplementary Fig. 7 for results separated by condition, Supplementary Table 1 for sample sizes and Supplementary Data 1 for the data and computer code that generate this figure. All errorbars are 95% confidence intervals, computed via bootstrapping.
