... the trade-off between growth and thermoregulation, but the effects of temperature on the ontogeny of endothermy are not fully understood. Therefore, we experimentally tested whether heating the nest cup of Eurasian blue tits ( Cyanistes caeruleus ) during incubation would influence cold tolerance...

...-shivering thermogenesis was not reinforced by sea acclimatization. This result suggests that king penguins mainly rely on skeletal muscle contraction (shivering or locomotor activity) to maintain endothermy at sea. Sea-acclimatized immature penguins also exhibited higher shivering efficiency and oxygen...

We investigated at what age the precocial king quail Coturnix chinensis can defend a high T b under a mild thermal challenge and whether they can express torpor soon after achieving endothermy to overcome...

...Vincent Careau; Bethany J. Hoye; Terence W. O'Dwyer; William A. Buttemer The aerobic capacity model proposes that endothermy is a by-product of selection favouring high maximal metabolic rates (MMR) and its mechanistic coupling with basal metabolic rate (BMR). Attempts to validate this model...
