TL;DR: In free-living imperial cormorants, ODBA, and hence estimated VO2, was higher during the return flight of a foraging bout, and decreased with depth during the descent phase of a dive, supporting the use of accelerometry for the determination of activity-specific rate of energy expenditure.

TL;DR: In this article, the authors describe the major features and operating mode of a single device, the daily diary, an animal equivalent of the aeroplane ‘black box flight recorder’ which is designed to be used on a wide variety of species and which has already been tested on animals including albatrosses, badgers, cheetahs, cormorants, domestic dogs, horses, penguins, sharks, sunfish and turtles.

TL;DR: The results suggest that the running mean should be taken over a minimum period of 3 s for species with a dominant stroke period of up to this value and that static acceleration be derived over a period of no less than 1 stroke cycle.

TL;DR: This paper considers the advances that deadreckoning can bring to the study of the often cryptic movement and behaviour of marine animals at sea and suggests how movement data derived from these devices can be analysed using indices that allow interpretation over a large variety of temporal and spatial scales.

TL;DR: It is suggested, that the convergent use of similar gait patterns by distinct groups of animals points to universal physical and physiological principles that operate beyond taxonomic limits and shape common solutions to increase energetic efficiency.
