TL;DR: Overall, DBA seems to be a substantive proxy for movement-based power but consideration of other movement-related metrics, such as the Static Body Acceleration and the rate of change of body pitch and roll, may enable researchers to refine movement- based metabolic costs, particularly in animals where movement is not characterized by marked changes in body acceleration.

TL;DR: A dynamic multi-compartment gas exchange model is used to estimate blood and tissue O2, CO2, and N2 from high-resolution dive records of two different common bottlenose dolphin ecotypes inhabiting shallow and deep diving life styles, indicating that cardiac output had to remain elevated during surface intervals for both ecotypes.

TL;DR: It is suggested that diving mammals vary their physiological responses according to multiple stressors, and that the perspective on marine mammal diving physiology should change from simply minimizing N2 loading to management of the N2 load.

TL;DR: The validity of using changes in depth profiles from high-resolution time-depth recorders to infer feeding activity in free-ranging penguins is examined, as more accessible proxies of their feeding success.

TL;DR: Heart rate (fh) and the energetic costs of specific behaviours of king penguins while ashore and while foraging at sea during their breeding period are determined and it is suggested that the regional hypothermia that has been recorded in this species during diving bouts may be at least a contributing factor to such hypometabolism.
