Shifts of thermogenesis in the prairie vole (Microtus ochrogaster)

  title={Shifts of thermogenesis in the prairie vole (Microtus ochrogaster)},
  author={Bruce A. Wunder and David S. Dobkin and Ronald D. Gettinger},
The weight-specific oxygen consumption ( $$\mathop V\limits^ \bullet _{{\rm O}_2 } $$ ) of prairie voles caught in winter is 24% higher at 27.5° C and 29% higher at 7.5° C than that of summer animals, thus affording a higher weight-specific thermogenesis in winter than in summer which may allow tolerance to lower thermal exposures. Coincident with the increase in weight-specific rates of oxygen consumption is a decrease in body weight. When total energetic cost to maintain an animal per unit… CONTINUE READING
