Figure 1.
Growth suppression of red-eyed treefrog (Agalychnis callidryas) tadpoles through 8 days of exposure to indirect chemical cues of predation from dragonfly nymph predators (Anax amazili) fed different biomasses and numbers of A. callidryas prey.
The y-axis depicts percent growth reduction, which reflects differences in the total lengths of tadpoles from the beginning to the end of the experiment relative to the mean growth of tadpoles in the predator-free controls. Thus larger values indicate greater reductions in growth. Growth suppression was dose-dependent and its asymptotic magnitude was greater when predators ate multiple prey than when they ate single prey of equivalent biomass.
