Table 1 Candidate models (within 2 AIC units of the best model) for multivariate regressions relating response variables to the sensitivity (“Sens”) and exposure (“Exp”) of butterflies (n = 24) and moths (n = 131) to climate.

SEs are provided within brackets; bold values indicate individually significant effects. Response variables were standardized values of changes in abundance, distribution size, and northern range margin; the latter two variables were calculated using well-recorded 10 × 10–km grid squares (hectads) and standardized before analysis to enable comparisons between the size and direction of coefficients.
