Figure 1. Foraging effort response to time of day.

The predicted response of A) proportion of time diving (%), B) mean dive duration (s), C) mean post-dive duration (s) and D) vertical distance covered (m·h⁻¹) in female Australian fur seals to different times of the day. Grey areas represent local night time and the hatched regions represent the band of time that sunrise/sunset occurred over the study period. Blue bands represent the 95% confidence intervals around the predicted response. (see Table 1 for statistical results).
