Abstract

Correction: Coadaptation of Offspring Begging and Parental Provisioning - An Evolutionary Ecological Perspective on Avian Family Life

Highlights

The family, which is defined as a social unit consisting of one or two parents and their offspring, forms a social environment with significant consequences for individual fitness and trait evolution
Removing the term ‘‘total number of dips given by foster parents’’, which was included to control for the effect of the feeding rates of the foster parents on the begging of the focal nestlings, made little difference to the results (F1,16 = 1.12, P = 0.31)
The family life in species with parental care typically creates a social environment in which traits such as offspring begging and parental feeding that are expressed by one family member exert a selective pressure on the trait expression in another family member. These traits should become genetically correlated [1], [15]. Such genetic correlations are expected to be positive when parents control the level of parental provisioning and selection predominantly acts on offspring begging and vice versa in case of a negative correlation

Summary

Introduction

The family, which is defined as a social unit consisting of one or two parents and their offspring, forms a social environment with significant consequences for individual fitness and trait evolution. Social interactions between parents and offspring as expressed in the family context are of particular interest, since these traits are target of selection but can act as agent of selection by exerting a selective pressure on the trait expression of other family members [1]–[3] Both the social trait expressed and the social environment can evolve [2]. Offspring begging and parental feeding have a heritable basis [10]–[14] and are able to respond to selection Their evolution may not be independent, as the expression of each of these traits depends on the expression of the other. A phenotypic covariation of parental provisioning and offspring begging may depend on (prenatal) maternal effects [10], [16], [20]
