Figure S1. Relationship between starting weight, diet and three measures of tadpole performance, fitted by models non assuming similar slopes between the different food treatments. (a): weight at 33 days; (b): weight at 44 days; (c): age at metamorphosis. Diamonds, dashed lines: low protein diet; crosses, continuous lines: high protein diet. Lines represent values fitted by models. For each measure of tadpole performance, slopes were not significantly different among treatments (see results).
