Table 3. Summary results of models assessing the response of foraging trip duration (h) to the corresponding proportion of time spent diving and time of year, the response of the proportion of time spent diving during a foraging cycle to the time of year and the response of haul-out duration (h) to the corresponding foraging trip duration and time of year in female Australian fur seals provisioning young at Kanowna Island, Bass Strait, Australia.
