Figure 2.

For female Columbian ground squirrels (3 years of age and older), predicted probability by year (light gray lines, each dot represents an individual) of transitioning into breeder class from previous year's breeding status (left = failed breeders, N = 99, right = successful breeders, N = 321) based on emergence mass in the next year. Solid lines are average breeding probability with 95% confidence interval dashed lines.
