Isn't that just symbiotic relationship though? Article does not explain what monkeys get from this relationship with wolves and whether any species is changing another's behavior.
They don't get eaten by wolves.
I bet the feral dogs mentioned in the article will think twice before going near wolf/monkey groups too, since both dogs and wolves are usually territorial.
"However, the geladas don’t seem to get anything from the relationship, since the wolves are unlikely to deter other predators such as leopards or feral dogs, he says."
Don't babboons steal puppies and raise them to become their guard dogs?
Bit too loose for symbiotic. How about commensal relationship?
Or mutualism?
Maybe they benefit from a reduced rodent population in some way? Less disease or maybe even competition for food since this particular type of monkey grazes?
