...K. Mark Wooden; Glenn E. Walsberg SUMMARY We quantify the locomotor capacity of the round-tailed ground squirrel( Spermophilus tereticaudus ), a mammal that can lower energetic costs by relaxing thermoregulatory limits without becoming inactive. We measured maximum sprint speed, maximum limb...

...K. Mark Wooden; Glenn E. Walsberg SUMMARY This study quantifies the thermoregulatory ability and energetics of a mammal, the round-tailed ground squirrel Spermophilus tereticaudus ,that can relax thermoregulatory limits without becoming inactive. We measured body temperature and metabolic rate...

... from 0.25 to 1.00 m s −1 on the metabolic rate and body temperature of the round-tailed ground squirrel Spermophilus tereticaudus. 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...
