Figure 1From: Effects of brood size manipulation and common origin on phenotype and telomere length in nestling collared flycatchersEffect of the experiment on final brood size and nestling phenotype. Mean ± s.e. (a) number of 12-day-old nestlings per experimental nest, (b) nestling body mass, (c) tarsus length, and (d) log-transformed relative telomere length. Significant differences among treatments are highlighted with lines; *: p < 0.05 ; **: p < 0.0001).Back to article page
