From the study[1]:
"After reaching a criterion of ≥ 80% accuracy, bees demonstrated the learned concept of numerically less when presented with the numbers two to five(73.8 ± 1.9%; z score = 10.18, P <0.001). When presented with the unfamiliar numbers of one versus zero, bees chose the lower number of zero (63.0 ± 2.9%; z score = 4.23, P < 0.001; Fig. 1D), showing an understanding that an empty set is lower than one, which is challenging for some other animals."
