... that inhabit marine environments. There is therefore a demand for a framework through which to estimate energy expenditure from readily available data. We present the energetic costs associated with important time- and energy-intensive behaviours across nine families of marine bird (including seabirds, ducks...

Mice without access to water had significantly lower energy expenditures and in turn, reduced water loss compared to mice with access to water...

... to be facultative rather than obligate in many fish species ( Kolok, 1991 ; Suski and Ridgway, 2009 ; Hasler et al., 2009 ). Lethargic or dormant fish species may simply prioritize activity reduction in the cold to minimize energy expenditure. This prioritization may lead to the evolution of a consistent adaptive...

Exposure to predator odor increased energy expenditure, and both the thermogenic and energetic effects persisted when physical activity levels were controlled. Predator odor-induced muscle thermogenesis is subject to associative learning...

For example, energy management strategies of animals can be determined from the regression slope estimate of mean energy expenditure against resting...
