We present the first continuous, multi-day heart rate recordings of newly weaned, wild southern elephant seals. The effects of circadian periodicity and weather conditions on heart rate are examined. Changing climate regimes may affect the energetic requirements experienced during, and thus the energetic trade-off that concludes, the post-weaning fast.
