Comparison of nest survival models. The model including only fat class as predictive factor (φ[fat class]) best explained the variation in the data and had a significant better fit (χ²=5.86, p < 0.016) than the next best model in which survival was constant, i.e. independent of fat class and time (φ[.]; φ = survival probability).
