Table 1. Factors impacting volume of 10% sucrose solution collected treating GRS as an Ordinal Variable.

GLMM parameter estimates (Est.), standard errors (SE), and P values of potential factors IMPACTING 10% sucrose solution load size
Parameter Est. SE Statistical Significance
Intercept 25.05 5.54 ****
Total Ovariole Number −0.11 0.49
GRS 0.12 0.85
Total Ovariole Number × GRS −0.49 0.23 *
Hive ID 2.69 2.33

Note that there is a significant interaction effect of ovariole number and GRS (sucrose sensitivity). Hive ID includes error caused by Colony source of bees and temporal pattern of data collection (Generalized Linear Mixed Model, N = 131, * = p<0.05, **** = p<.0001).
