Correlation coefficients and significance levels of honey flow variables as predictors of autumn and winter colony loss rates. N = number of data points, GDD = growing degree days. For an explanation of geographic levels (Germany, RP, Regions), please refer to text. The number of observations are reported in Tables S2–S4.
