Fig. 1From: Long-term individualized monitoring of sympatric bat species reveals distinct species- and demographic differences in hibernation phenologyObserved longest hibernation periods per year for Natterer’s bats and Daubenton’s bats. Horizontal boxplots denote entrance and emergence dates (vertical line: median; filled circle: mean; open circles: entrance date outliers; x: emergence date outliers); the period spent inside the hibernaculum is denoted by the shaded area between boxplots. Corresponding calender dates of entrance, emergence and duration of the longest hibernation periods per year are provided in Additional file 1Back to article page
