... 2023 Summary: Robust phylogenetic comparative analyses demonstrate the tissue-dependent effect of bird body mass on mitochondrial bioenergetics, questioning the mechanisms and levers modulating allometric patterns in different tissues, and the involvement of body mass in individual performance...

..., here, repeated exposure to cold triggered an acclimatory response, resulting in unchanged mitochondrial bioenergetics. Immediately after cold exposure, we observed an increase in the overall pool of ATP and a decrease in typical antioxidant enzyme activity. We also observed decreased activity...

... rate (FMR) using published bioenergetic models. The intra-seasonal loss in body condition of different reproductive classes (calves, juveniles, adults, pregnant and lactating females) was converted to blubber energy loss and total energy expenditure (TEE). Using these two metrics, we tested the effects...
