Relationships between a reproductive female's probability of weaning a foal (survival to year t + 1) and (a) female quality, (b) female age in year t, (c) winter severity after birth, and (d) local density. The fixed effects not represented in the plots are set to its mean values and horse identity is included as a random factor (n _horse = 113, n _observations = 321). The solid lines and the shaded areas depict relationships predicted by the selected models and their 95% confidence intervals, respectively
