The same pattern was true for first winter survival with the quadratic effect of maternal age being marginally significant when birth weight was removed (χ 2 1 = 3.85, p = 0.050).
The same pattern was true for first winter survival with the quadratic effect of maternal age being marginally significant when birth weight was removed (χ 2 1 = 3.85, p = 0.050).
Applying both restrictions the effect became marginally non-significant (coefficients=-6.65 ± 3.49, χ 2 1 = 3.62, p = 0.057) Decomposing first year survival into summer and winter survival indicated that the effect of offspring inbreeding coefficient on first year survival is driven by its effect on winter survival (coefficient=-15.2 ± 3.43, χ 2 1 = 19.6, p < 0.001, table 3 ).
