... environment, to cooling down through the evaporation of body fluids and synthesizing heat shock proteins to prevent damage at the cellular level after heat exposure. In contrast, endothermy may allow an insect to fight parasitic infections, fly within a large range of T a and facilitate nest defense. Since...

Therefore, we experimentally tested whether heating the nest cup of Eurasian blue tits ( Cyanistes caeruleus ) during incubation would influence cold tolerance...

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...

However, it is unclear how selection at HA for shivering thermogenesis acts early in the development of small altricial mammals, which are born with immature skeletal muscles and without the capacity for homeothermic endothermy.

...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...
