... measured continuously. Both oxygen consumption and heart rate increased severalfold during digestion, and metabolic heat production increased core body temperature by 2°C, explaining 12% of the observed tachycardia. The rise in core body temperature means that standard metabolic rate increased during...

As wind speed increased from 0.25 to 1.00 m s −1 , metabolic heat production increased by 0.94 W in the absence of solar radiation and by 0.98 W in the presence of 950 W m...

... leucophrys gambelii ). We measured changes in metabolic heat production by exposing birds to different wind speeds (0.25, 0.5, 1.0 and 2.0 m s −1 ) and irradiance combinations (<3W m −2 and 936±11 W m −2 ; mean ± S.D.) at an air temperature of 10 °C. Body temperature was not affected by wind speed...

... helpful comments on the manuscript. This work was supported by the US NSF grant IBN-9601089. Several lines of evidence suggest that the flight apparatus of hummingbirds facilitates metabolic heat production, with the wings and thorax acting as a resonant system. In hovering ruby-throated...

...Glenn E. Walsberg; Randall L. Tracy; Ty C. M. Hoffman ABSTRACT Endotherms exposed to air temperatures below thermal neutrality reduce their metabolic heat production when exposed to sunlight. The physiological effects of this additional source of heat gain from the environment usually are assumed...
