TABLE 1.
Phenotyping of the torpor incidence groups according to the torpor parameters of approach 1.
| Torpor characteristics | Given values | Torpor incidence group | ANOVA | Post hoc test with p < 0.050 | ||||
| Never torpor (n = 14) | Rarely torpor (n = 12) | Sometimes torpor (n = 22) | Often torpor (n = 12) | Test statistics | p-value | Comparison | ||
| Torpor per definition incidence | Median | – | 0.1 | 0.3 | 0.7 | H(2) = 40.0 | <0.001 | Rarely vs. sometimes |
| Rarely vs. often | ||||||||
| Sometimes vs. often | ||||||||
| Torpor attempt incidence | Median | – | 0.0 | 0.2 | 0.1 | H(2) = 3.1 | 0.215 | – |
| Torpor onset (ZT) | Median | – | 2.6 | 2.0 | 1.0 | H(2) = 8.4 | 0.015 | Rarely vs. often |
| Sometimes vs. often | ||||||||
| Torpor offset (ZT) | Mean | – | 5.5 | 5.5 | 5.1 | F(41,2) = 0.2 | 0.823 | – |
| Torpor duration (min) | Mean | – | 174 | 200 | 246 | F(41,2) = 1.4 | 0.259 | – |
| Minimal torpor Tb (°C) | Mean | – | 27.2 | 26.5 | 25.4 | F(41,2) = 1.6 | 0.219 | – |
One week was analyzed. The grouping is based on the torpor per definition incidence (Figure 4). Each hamster’s mean value per torpor parameter (onset, offset, duration, and minimal torpor body temperature) was included in the comparison. More details on the statistical tests are listed in Supplementary Table 2.
