Abstract: 1. The thermogenic properties of mitochondria in liver, brown adipose tissue (BAT) and muscle, and uncoupling protein 1 (UCP1) contents in BAT were studied in field-captured gray red-backed vole (Clethrionomys rufocanus), large Japanese field mouse (Apodemus speciosus) and striped field mouse (Apodemus agrarius) in summer from the Northeastern China. 2. The mitochondrial respiration capacities in liver, cytochrome c oxidase activities in BAT and muscle, and UCP1 contents in BAT were found to be significantly higher in gray red-backed vole than that in large Japanese field mouse and striped field mouse. 3. High thermogenic capacities in liver, BAT and muscle in gray red-backed vole can enable them to increase survivals. Different strategies were employed by gray red-backed vole, large Japanese field mouse and striped field mouse to adapt their environments. [Copyright &y& Elsevier]
