Galetti, M., & Sazima, I. (2006). Impact of feral dogs in an urban Atlantic forest fragment in southeastern Brazil. Natur. Conservation, 4, 146-151.
Feral domestic dogs are one of the main predators of native wildlife in protected areas all over the world. However, the number of prey killed by feral dogs is poorly recorded. A total of 46 carcasses of at least 12 vertebrate species killed by dogs were found along 44 months in an urban, 250 ha Atlantic forest fragment in southeastern Brazil. Feral dogs showed no apparent selection towards different species of prey, killing from small frogs to deer. Mammals were the most frequent prey found (75%). Our data indicate that feral dogs have a great impact on wildlife in the Atlantic forest, especially in areas where wildlife needs to move between forest fragments. Eradication programs, although controversial, are the only way to reduce wildlife predation by feral dogs.
