While wood mice, for example, have what is generally known as a “ fast ” life history, common dormice apparently have some flexibility to adjust their life history tactics ( early versus delayed reproduction ) to circumstances.
Dr. Claudia Bieber and her fellow scientists hypothesized that the ability to hibernate may explain this unusual bimodal birth pattern in the hazel dormouse.
So far relatively little is known about hibernation and survival rates of small hibernators, such as common dormice.

Claudia Bieber und ihr Team nehmen an, dass die Ursache dieses ungewöhnlichen, bimodalen Musters der Geburtstermine im Auftreten des Winterschlafs bei dieser Tierart liegt.
Bislang wissen Forschende relativ wenig über die Überlebensraten von kleinen Winterschläfern.
