From: Co-founding ant queens prevent disease by performing prophylactic undertaking behaviour
Biting and burial of co-foundress corpses improve queen survival. The number of queens surviving following the death of a co-foundress due to infection, was significantly increased when they performed a biting and b burial, whereas there was no significant effect for c removal (error bars show ±95% CIs given; letters denote significant GLM results at α = 0.05; n.s. = non-significant).
