Summary Time and energy are key currencies in animal ecology, judicious management of these is a primary focus for natural selection. At present, however, there only two main methods estimation rate expenditure the field, heart doubly labelled water, both which have been used with success; but also their limitations. The deployment data loggers that measure acceleration emerging as powerful tool quantifying behaviour free‐living animals. Given movement requires use energy, accelerometry...

Dynamic body acceleration (DBA) has been used as a proxy for energy expenditure in logger-equipped animals, with researchers summing the (overall dynamic - ODBA) from three orthogonal axes of devices. The vector (VeDBA) may be better so this study compared ODBA and VeDBA proxies rate oxygen consumption using humans 6 other species. Twenty-one on treadmill ran at different speeds while equipped two loggers, one straight orientation skewed, () was recorded. Similar data were obtained animals...
The p-value has long been the figurehead of statistical analysis in biology, but its position is under threat. p now widely recognized as providing quite limited information about our data, and being easily misinterpreted. Many biologists are aware p's frailties, less clear how they might change way analyse their data response. This article highlights summarizes four broad approaches that augment or replace p-value, relatively straightforward to apply. First, you can your with confident it,...
Rates of aerobic metabolism vary considerably across evolutionary lineages, but little is known about the proximate and ultimate factors that generate maintain this variability. Using data for 131 teleost fish species, we performed a large-scale phylogenetic comparative analysis how interspecific variation in resting metabolic rates (RMRs) maximum (MMRs) related to several ecological morphological variables. Mass- temperature-adjusted RMR MMR are highly correlated along continuum spanning...

The oxygen store/usage hypothesis suggests that larger animals are able to dive for longer and hence deeper because storage scales isometrically with body mass, whereas usage allometrically an exponent <1 (typically 0.67–0.75). Previous tests of the allometry diving tend reject this hypothesis, but they based on restricted data sets or invalid statistical analyses (which assume every species provides independent information). Here we apply information‐theoretic methods phylogenetically...
Measurement of acceleration can be a proxy for energy expenditure during movement. The variable overall dynamic body (ODBA), used in recent studies, combines the elements recorded all three dimensions to measure and hence due However, simplicity ODBA affords it limitations. Furthermore, while accelerometry data loggers enable measures stored, recording at high frequencies represents limit deployment periods as result logger memory and/or battery exhaustion.

Abstract The tortuosity of the track taken by an animal searching for food profoundly affects search efficiency, which should be optimised to maximise net energy gain. Models examining this generally describe movement as a series straight steps interspaced turns, and implicitly assume no turn costs. We used both empirical‐ modelling‐based approaches show that energetic costs turns in terrestrial aerial locomotion are substantial, calls into question value conventional models such correlated...
SUMMARY Several methods have been used to estimate the energy expenditure of free-ranging animals. A relatively new technique uses measures dynamic body acceleration as a calibrated proxy for and has proved an excellent predictor in active However, some animals can spend much their time inactive still expend at varying rates range physiological processes. We tested utility during (locomotion, eating) (digesting, thermoregulating)behaviours exhibited by domestic chickens. also compared this...
