Figure 1From: Mechanisms of social regulation change across colony development in an antPercentage of eggs recovered after 24 hours. Egg-policing behaviour changed dramatically as colonies grew. Workers from small colonies tolerated eggs laid by their own queen (OQ), eggs laid by a foreign, established queen (FQ), and eggs laid by workers (W), whereas workers from large colonies destroyed worker-laid eggs. Points, boxes, and whiskers represent medians, quartiles, and ranges, respectively. Horizontal bars indicate no difference in the survival of eggs from different sources within a size class at α = 0.05; letters indicate differences in survival of eggs from a given source between size classes at α = 0.05. Randomized multi-factor ANOVA, N = 15, F = 13.74, p10,000 < 0.0001.Back to article page
