Phys.org / Air pollution causes social instability in ant colonies, triggering attacks on returning nest mates

A research team from the Max Planck Institute for Chemical Ecology has shown in a new study that ants returning from habitats affected by air pollution are attacked when they re-enter the colony. The cause: air pollution, ...
