Fig 2. Adult females from low quality territories are significantly less likely to reproduce as they age.

The relationship between probability of reproduction and maternal minimum age (mmage) for the four levels of territory quality (TQ₄). Colours denote TQ₄ where blue = 1, green = 2, orange = 3 and red = 4. Lines present predictions and shading denotes areas within the 95% prediction intervals, averaged from the top set of GLMM models.
