Variance due to the random factors. The variance of Group Factor “Apiary” described the high level of the variability explained by the difference between apiary.

Model Variance (Intercept)
Group = Apiary
Variance
Hive
Residuals variance
Model A 46.20 0.0689 30.995
Model B 2015 57.94 0.040 20.050
Model B 2016 44.34 0.0977 40.486
Model B 2017 26.15 0.00377 21.11

The variance at Hive levels is very low. The residual variances is linked with the effect of fixed factors (see Tab. 1).
