Appendix C. A table summarizing model selection results relating offspring survival to sex, density, and parental dispersal phenotype.
Table C1. Table summarizing model selection results relating offspring survival to sex, density and parental dispersal phenotype. Offspring survival is estimated from the time of first capture. Independent variables are the dispersal phenotype of each parent (mother's DP, father's DP, each modeled as a binary trait), density in the year of birth (modeled as a binary trait), and sex. LR is the likelihood ratio of the relevant model to the null model (with no independent variables), and p(LR) is the associated p value. N = 474, the total number of animals whose parents’ dispersal phenotypes are known.
