What fauna populations have been severely impacted by yellow crazy ants on Christmas Island?
Answer
Hermit crabs and native reptiles
The destructive ecological consequences of the yellow crazy ant invasion are perhaps most starkly illustrated by the damage observed on Christmas Island. In this environment, the aggressive nature and overwhelming numbers of the invasive ants have led to severe population declines among specific groups of native fauna. The primary victims highlighted are the island's hermit crabs and various species of native reptiles. The ants displace or directly prey upon these ground-dwelling creatures. Furthermore, the sheer physical mass of the invading ant biomass effectively suffocates the normal functioning of the native ecosystem, preventing the original inhabitants from thriving or recovering.
