Figure 1

Number of small and large Caenorhabditis elegans consumed by Prionchulus muscorum within 4 h at offered nematode densities of 5–300 individuals, in the absence and presence of substrate. Data from all six replicates are shown. The curves represent the best-fitting functional response model (flexible type III functional response, see Eq. 3 in the text); 95% bootstrapped confidence intervals are shown as well. Parameter estimates are given in Table 2.
