Data from: Species divergence in offspring begging and parental provisioning is linked to nutritional dependency

Alexandra Capodeanu-Nägler, Anne-Katrin Eggert, Heiko Vogel, Scott K. Sakaluk & Sandra Steiger
In animal species in which parents provide food to their dependent young, offspring often display conspicuous begging signals. These solicitation behaviors are important components of parent–offspring communication, but it is currently unclear how they and the parental response covary with offspring dependency on parental food provisioning across species. Burying beetles (Nicrophorus) are well known for providing elaborate biparental care, including provisioning of begging larvae. By using a multispecies approach, we show that larval begging intensity,...
