Fig. 2.

The influence of maternal condition (a) and migration distance (b) on late‐stage fetal development of mule deer in western Wyoming, USA, 2016–2019. Maternal condition was measured as ingesta‐free body fat (IFBFat) in December, whereas late‐stage fetal development was measured as fetal eye diameter in March. Both IFBFat and fetal eye diameter were measured using ultrasonography. The gray polygons represent the 95% confidence intervals for the predicted values (black line). The data points represent marginal effects at the mean for other covariates in the model.
