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.

... ) and, hence, body mass gain ( Jørgensen and Blix, 1985 ). We investigated whether variation in incubation temperature alters thermoregulation over short time periods, similar to feeding bouts in the wild. We incubated Japanese quail ( Coturnix japonica ) eggs at three biologically relevant temperatures...

... 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...

Wolf ABSTRACT Because most desert-dwelling lizards rely primarily on behavioral thermoregulation for the maintenance of active body temperature, the effectiveness of panting as a thermoregulatory mechanism for evaporative cooling has not been widely explored. We measured...
