Title Pearson r of 7 traits_population wide_table3
Downloaded 3 times
Description Test for assortative mating for various quality traits of males and females (seven traits) calculated at the population-wide. At the population level, sample size (n) indicates the number of pairs for which a Pearson correlation coefficient was calculated. ‘Fitness’ refers to the number of eggs laid (female fecundity) or fertilized (male siring success). PCA score refers to the estimate of overall quality (Table 2) based on the other breeding round, i.e. when not paired to the focal partner.

Title Pearson r of 7 traits_within aviary_table3
Downloaded 3 times
Description Test for assortative mating for various quality traits of males and females calculated at the within-aviary level. At the aviary level, the sample size indicates the number of aviaries for which a Pearson correlation coefficient was calculated; shown are the mean correlation coefficients for each trait. ‘Fitness’ refers to the number of eggs laid (female fecundity) or fertilized (male siring success). PCA score refers to the estimate of overall quality (Table 2) based on the other breeding round, i.e. when not paired to the focal partner.

Title Pearson r of Pairing status_table 4
Downloaded 5 times
Description Test for assortative mating for male versus female estimates of quality (PCA scores, Table 2) across pairs of various status categories (all pair bonds observed, all exclusively monogamous relationships, the subset of monogamous relationships that lasted until the end of a breeding round, and all polygamous relationships).

Title model testing the differential-allocation hypothesis_table5
Downloaded 5 times
Description Data for the linear mixed-effect model testing the differential-allocation hypothesis based on observations of the proportion of female incubation in 283 out of 292 lasting monogamous pairs that initiated breeding. The dependent variable is the relative count of female versus male nest visit (FIDInc and MIDinc) records (using the ‘cbind’ function in R) within each pair. The random effects male and female identity (ID) reflect the individual repeatability across different partners (variance component V), while the random effect pair ID controls for overdispersion in the binomial counts. The predictor of interest (quality difference) is the difference in estimated quality between the partners (female PCA score minus male PCA score:diff_FM).
