Results of mixed-models analyzing nestling phenotypic variance in relation to brood size manipulation experiment (fixed effect), nest of origin and nest triplet (random effects; see text)
Body mass Tarsus length Relative telomere length
Fixed effects d.f. F p-value d.f. F p-value d.f. F p-value
brood size manipulation 2,273.5 11.210 < 0.001 2,272.2 0.918 0.400 2,166.3 0.792 0.455
Random effect var. comp.(s.e.) LRT p-value var. comp. (s.e.) LRT p-value var. comp. (s.e.) LRT p-value
nest of origin 0.747 (0.210) 23.113 < 0.001 0.148 (0.042) 21.994 < 0.001 0.014 (0.009) 2.159 0.038
nest triplet 0.374 (0.220) 2.141 0.039 0.047 (0.038) 0.870 0.187 0.027 (0.012) 4.460 0.003
error 0.951 (0.083) 0.190 (0.016) 0.116 (0.010)

Significance of fixed effects were tested using Wald F-statistics and of random effects using log-likelihood ratio tests (LRT).
