Inheritance of material wealth in a natural population

Evolutionary adaptation occurs when individuals vary in access to fitness-relevant resources and these differences in “material wealth” are heritable. It is typically assumed that the inheritance of material wealth reflects heritable variation in the phenotypic abilities needed to acquire material wealth. We scrutinize this assumption by investigating additional mechanisms underlying the inheritance of material wealth in collared flycatchers. A genome-wide-association analysis reveals a high genomic heritability (h2=0.405+/-0.08) of access to caterpillar larvae, a fitness-relevant resource, in the birds’ breeding territories. However, we find little evidence for heritable variation in phenotypic abilities needed to acquire this material wealth. Instead, combined evidence from simulations, experimental, and long-term monitoring data indicate that inheritance of material wealth is largely explained by philopatry causing a within-population genetic structure across a heterogeneous landscap..., long term monitoring of a wild nestbox breeding population, , # Data from: Inheritance of material wealth in a natural population

This is the data and code accompanying the publication of \" Inheritance of material wealth in a natural population \", submitted for consideration at Ecology Letters. This record contains all datasets and code necessary to reproduce the analyses, which consists in natural records of phenotypic traits, access to resources (food) and dispersal behaviour, quantitative genetic (full pedigree) and genomic analyses (GWAS on 38705 SNPs) on wild collared flycatchers (Ficedula albicollis) in the long-term monitoring population of Öland, Sweden.
