... 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...

... and McKechnie, 2014 ; Page et al., 2011 ). Relationships between resting evaporative heat loss, metabolic heat production and T b at high T air are typically quantified using open flow-through respirometry (e.g. Dawson, 1954 ; Lasiewski et al., 1966 ). Two approaches are commonly used for obtaining...

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...
