Correction

Following publication of the original article [1], the authors reported an error in the caption of Fig. 4.

Originally, the incorrect figure caption was published as:

Fig. 4 Effects of huddling and cold on the concentrations of short-chain fatty acids (SCFAs). The concentrations of acetic acid (a), propionic acid (b), butyric acid (c), isobutyric acid (d), valeric acid (e), and isovaleric acid (f) in huddling and separated Brandt’s voles at warm and cold Ta (n = 7–9/group). *P < 0.05

The correct caption is:

Fig. 4 Effects of huddling and cold on the concentrations of short-chain fatty acids (SCFAs). The concentrations of acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, and isovaleric acid in huddling and separated Brandt’s voles at warm and cold Ta (n = 7–9/group). *P < 0.05
