Description
Summary:Intra-group relatedness does not necessarily imply kin selection, a leading explanation for social evolution. An overlooked mechanism for generating population genetic structure is variation in longevity and fecundity, referred to as individual quality, affecting kin structure and the potential for cooperation. Individual quality also affects choosiness in partner choice, a key process explaining cooperation through direct fitness benefits. Reproductive skew theory predicts that relatedness decreases with increasing group size, but this relationship could also arise due to quality-dependent demography and partner choice, without active kin association. We addressed whether brood-rearing eider (Somateria mollissima) females preferentially associated with kin using a six-year data set with individuals genotyped at 19 microsatellite loci, and tested whether relatedness decreased with increasing female group size. We also determined the relationship between local relatedness and indices of female age and body ... : GroupwiseCoalition specific data used to clarify the connection between intragroup relatedness and group size, while controlling for breeding strategy. First column contains the year, second column female ring number, third column ("median.R") is the mean median relatedness in the coalition, fourth column ("Strategy numbers") contains the coded strategies, where 1 = enduring coalition, 2 = transient coalition and 3 = brief association, the fifth column describes group size.RelativesThe file describing the frequency of relatives in the population. First column contains the females' ring numbers, the second one the relative frequency of relatives in the population, third column = minimum age estimate, the last column (GLOBAL_CI) is the global condition index.Genotypes19 loci genotypes for the 529 females genotyped for this study. ...
