... electrocardiogram (ECG) in the beluga whale, bottlenose dolphin, false killer whale, killer whale ( Orcinus orca ) and pilot whale ( Globicephala macrorhynchus ) to evaluate cardiorespiratory coupling while breathing spontaneously under voluntary control. The results show that cetaceans have a strong respiratory...

... values provide the first data on SV and CO in awake and unrestrained cetaceans in water. Summary: Transthoracic ultrasound determines heart rate and stroke volume before and after exercise in bottlenose dolphins, providing the first data on the extreme cardiovascular plasticity in awake...

... with a significant difference between low fat (13.9±4.8 days) and high fat diets (22.0±0.5 days). Overall, our results indicate that while assuming a Δ 13 C value of 1‰ may be appropriate for cetaceans, Δ 15 N values may be closer to 1.5‰ rather than the commonly assumed 3‰. Our data also suggest that understanding...

...JOSEPH L. KIRSCHVINK; ANDREW E. DIZON; JAMES A. WESTPHAL We tested the hypothesis that cetaceans use weak anomalies in the geomagnetic field as cues for orientation, navigation and/or piloting. Using the positions of 212 stranding events of live animals in the Smith sonian compilation which fall...
