Measuring metabolic rate in the field: the pros and cons of the doubly labelled water and heart rate methods
Summary 1 Measuring the metabolic rate of animals in the field (FMR) is central to the work
of ecologists in many disciplines. In this article we discuss the pros and cons of the two most …

The heart rate method for estimating metabolic rate: review and recommendations
JA Green - Comparative Biochemistry and Physiology Part A …, 2011 - Elsevier
Under most circumstances heart rate (fH) is correlated with the rate of oxygen consumption
(V˙ o2) and hence the rate of energy expenditure or metabolic rate (MR). For over 60years …

Moving towards acceleration for estimates of activity‐specific metabolic rate in free‐living animals: the case of the cormorant
Summary 1 Time and energy are key currencies in animal ecology, and judicious
management of these is a primary focus for natural selection. At present, however, there are …

Tri-axial dynamic acceleration as a proxy for animal energy expenditure; should we be summing values or calculating the vector?
Dynamic body acceleration (DBA) has been used as a proxy for energy expenditure in
logger-equipped animals, with researchers summing the acceleration (overall dynamic body …

Accelerometry to estimate energy expenditure during activity: best practice with data loggers
Measurement of acceleration can be a proxy for energy expenditure during movement. The
variable overall dynamic body acceleration (ODBA), used in recent studies, combines the …

Seasonal adjustment of energy budget in a large wild mammal, the Przewalski horse (Equus ferus przewalskii) II. Energy expenditure
Many large mammals show pronounced seasonal fluctuations of metabolic rate (MR). It has
been argued, based on studies in ruminants, that this variation merely results from different …

Miniaturization of biologgers is not alleviating the 5% rule
SJ Portugal, CR White - Methods in Ecology and Evolution, 2018 - Wiley Online Library
The use of biologging technology has increased exponentially over the last decade,
allowing us to study animal behaviour at a level of detail not previously possible. It is clear …

Accelerometers can measure total and activity‐specific energy expenditures in free‐ranging marine mammals only if linked to time‐activity budgets
Energy expenditure is an important component of foraging ecology, but is extremely difficult
to estimate in free‐ranging animals and depends on how animals partition their time …

How do marine mammals manage and usually avoid gas emboli formation and gas embolic pathology? Critical clues from studies of wild dolphins
Decompression theory has been mainly based on studies on terrestrial mammals, and may
not translate well to marine mammals. However, evidence that marine mammals experience …
