Data from: Tadpole begging reveals high quality

Matthew B. Dugas, Stephanie A. Strickler & Jennifer L. Stynoski
Parents can benefit from allocating limited resources non-randomly among offspring, and offspring solicitation (i.e., begging) is often hypothesized to evolve because it contains information valuable to choosy parents. We tested the diagnostic predictions of three ‘honest begging’ hypotheses –Signal of Need, Signal of Quality, and Signal of Hunger – in the tadpoles of a terrestrial frog (Oophaga pumilio).
