... between growth and thermoregulation, but the effects of temperature on the ontogeny of endothermy are not fully understood. We therefore experimentally tested whether heating the nest cup of Eurasian Blue Tits ( Cyanistes caeruleus ) during incubation would influence cold tolerance of the chicks after...

... traits vary with fine-scale microclimate, but this has received less attention in endotherms. Here, we test the hypothesis that avian thermoregulation varies with microclimate and behavioural constraints in a non-passerine bird.

... of thermoregulation can also be immense, yet our understanding of whether a stress response is sufficient to induce changes in thermoregulatory investment is limited. Using the black-capped chickadee as a model species, we tested a hypothesis that stress-induced changes in surface temperature ( T s ), a well...

... at and below thermoneutrality is thermoregulatory. An alternate hypothesis is that control of insensible EWL, even at and below thermoneutrality, is a consequence of physiological thermoregulation. If EWL is affected by varying ΔWVP, then evaporative heat loss (EHL) will consequently be modified, requiring...
