| Description | Journal: Chronobiology international Subterranean common mole voles, Ellobius talpinus, were implanted with long-term recording electronic thermometers to obtain hourly body temperature $(T_{b}$) data during either the wintertime or summertime. The two individuals tested during the summertime had significant circadian and ultradian rhythms in their $T_{b}$. Four of the five mole voles tested during the wintertime lacked rhythmicity in their $T_{b}$. The fifth individual lacked circadian rhythms but had ultradian rhythms in its $T_{b}$. A loss of circadian rhythms in $T_{b}$ during deep torpor or hibernation has been reported for a few species of mammals. Inasmuch as the mole voles' wintertime $T_{b}$ remained at euthermic levels, our results show that a loss of circadian body temperature rhythms in mole voles does not require the low $T_{b}$ of deep torpor or hibernation. A tentative conclusion, based on these few animals, is that in common mole voles the $T_{b}$ rhythms may disappear during the wintertime even though their $T_{b}$ remains high.
