Table 1. Summary of parameter estimates, obtained from the long-term population study on great tits in Wytham Woods, required to estimate the critical rate of temperature change (η c), following the model by Chevin et al. [13].

Parameter Description Estimate (SE) Source
σ2h2 Additive genetic variance in laying date 2.62 (0.67) [31]
γ Strength of annual stabilising selection on laying date (based on number of recruits) 0.0061 (0.0010) This paper
T Generation time (average female age at reproduction, in years) 1.81 (0.01) [51]
rmax Maximum intrinsic rate of annual population growth 0.49 [28]
B Environmental sensitivity of selection (slope of annual caterpillar half-fall date against temperature) −5.30 (0.56) This paper
b Phenotypic plasticity (average individual slope of laying date against temperature) −4.98 (0.50) This paper
