Fig. 4: Low population; effect plots of trends in nestling tarsus (a) and telomere lengths (c) during artificial selection for smaller tarsus length in parents. The artificial selection ended after cohort 4 was born. The effect of selection category (0 : no parents selected (unselected), 0.5 : one parent selected, and1 : both parents selected) on tarsus (b) and telomere length (d) is shown.
Table 2: Linear mixed effects models with ∆AICc<5 of variation in early-life telomere length in house sparrow nestlings (n =566) in two island populations. All models included random intercepts for brood identity and year. The models are ranked by AICc, and number of degrees of freedom (df) and model weights (w) are shown.
