... as that of the heaviest birds, whereas BMR was positively correlated with mass at thermoneutrality ( Milbergue et al., 2018 ). We suggested that this phenomenon could be rooted in adjustments of metabolic intensity at the cellular level in cold-acclimated individuals. Interestingly, we observed here that in the cold...

... increased as diapause progressed, and acclimation to variable conditions altered both metabolic intensity and thermal sensitivity. However, incorporating these two types of metabolic plasticity into energy use models did not improve energy use estimates, validated by empirical measurements of energy stores...
