Abstract: The metabolic rate, thermal conductance, and the role of evaporative water loss in thermoregulation were determined in root voles Microtus oeconomus)from the Qinghai-Tibet Plateau. Root voles have high levels of basal metabolic rate and high levels of total thermal conductance, compared with the predicted values based on their body masses. while their body temperatures are relatively low. Evaporative water loss plays an important role in temperature regulation especially within and above the thermal neutral zone. All these characteristics have important adaptive significance for root voles to cope with extreme environmental conditions. Combined with the ecophysiological characteristics of other sympatricspecies the following conclusion was proposed that high metabolism, high thermal conductance and relative low body temperature are the common thermoregulatory characteristics for alpine nonhibernating small mammalian herbivores.
