Hunting habits die hard: Conserved prey preferences in army ants across two distant neotropical rainforests Open
Army ants are widely recognized as keystone species in neotropical rainforests due to their role as important arthropod predators. Their large‐scale raids involve thousands of workers scouring the forest floor in pursuit of prey, primarily…
