ABSTRACT

Daily torpor was regularly observed in captive Edible Dormice Glis glis, but there is a lack of such records under natural conditions. I report observations of five Edible Dormice in torpor encountered during regular controls of c. 190 nestboxes in the Białowieża Primeval Forest (northeastern Poland). The observations came from June 1994 and from June and July 1997. Rectal temperature of four individuals in torpor (16.5°C to 19.4°C) found in 1997 was lower than the morning air temperature.
