Appendix D. A table summarizing odds ratios of fecundity from a parallel MasterBayes analysis with dispersal distance fitted as a continuous variable.

Table D1. Table summarizing odds ratios of fecundity from a parallel MasterBayes analysis with dispersal distance fitted as a continuous variable. Odds ratios are also presented for fecundity as a function of density and for density × dispersal distance interactions. As in Table 3, parameters are presented as odds ratios, bolded where 95% HPD intervals do not overlap 1.0. Distance is evaluated per 100 m and density per 100 individuals. In order to allow more direct comparison with those presented using discrete dispersal phenotypes (Table 3), we also report the odds ratios at the average dispersal distance for each sex by dispersal category. The results are virtually identical to those from the model with discrete dispersal phenotypes; we find no impact on fecundity of dispersal to any distance (including philopatry). As when dispersal phenotype is defined discretely, we find that adult males born in years of high population density have lower fecundity; in this analysis, this effect is also (barely) seen in females.
