Working Papers from Santa Fe Institute

Abstract: In this article, we introduce a simple within-brood competitive growth model that maximizes parental fitness in unpredictable food conditions, in species that exhibit parental care, progressive provisioning, and an initial brood overproduction. We argue that competition between siblings may provide a proximate mechanism for parents to adjust the number of surviving offspring, or the social organization of the group in social species, to food conditions.
