Maned Wolf

• Diet
The Maned Wolf specializes in small and medium-sized prey, including small mammals (typically rodents and hares), birds, and even fish. A large fraction of its diet (over 50%, according to some studies) is vegetable matter, including sugarcane, tubers, and fruit (especially the Wolf Apple (Solanum lycocarpum). Captive Maned Wolves were traditionally fed meat-heavy diets and developed bladder stones. Zoo diets now feature fruits and vegetables, as well as meat and dog chow.
• Relations with other species
The Maned Wolf participates in symbiotic relationships with the plants that it feeds on, as it carries the seeds of various plants, and often defecates on the nests of leafcutter ants. The ants then use the dung to fertilize their fungus gardens, and later discard the seeds onto refuse piles just outside their nest. This process significantly increases the germination rate of the seeds. The wolf is particularly susceptible to infection by the giant kidney worm, a potentially fatal parasite that may also infect domestic dogs. The Maned Wolf is not a common prey species for any other predator, though it may be attacked or killed by feral domestic dogs.
