Seasonal changes of thermoregulation were studied in mole voles (Ellobius talpinus Pall.) from southern Siberia. Spontaneous fluctuations of body temperature were significantly higher in summer than in autumn. Standard deviations from average daily temperature of individuals were 0.95 (N=212) in summer and 0.57 (N=248) in autumn. Thermoregulatory response to cold exposure and to norepinephrine injection varied in different seasons of the year. In cold seasons, mole voles are able to maintain temperature homeostasis in a wide range of environmental conditions. This ability declined only in summer. Hence, the mole vole's adaptation to the continental climate is based on distinct seasonal variations of thermoregulation. In summer, thermoregulatory mechanisms are similar to those of desert eusocial fossorial species, but in spring and autumn, mole voles share the thermoregulatory strategies of boreal terrestrial rodents.
对来自西伯利亚南部的麝鼠（Ellobius talpinus Pall.）的体温调节季节性变化进行了研究。夏季体温的自发波动显著高于秋季。个体每日平均体温的标准差夏季为0.95（N = 212），秋季为0.57（N = 248）。一年中不同季节，对冷暴露和去甲肾上腺素注射的体温调节反应有所不同。在寒冷季节，麝鼠能够在广泛的环境条件下维持体温平衡。这种能力仅在夏季下降。因此，麝鼠对大陆性气候的适应基于体温调节明显的季节性变化。在夏季，体温调节机制类似于沙漠群居穴居物种，但在春季和秋季，麝鼠具有北方陆生啮齿动物的体温调节策略。
