Abstract

Disease, food and reproduction of the maned wolf - Chrysocyon brachyurus (Illiger) (Carnivora, Canidae) in southeast Brazil.

Abstract

The maned wolf (Chrysocyon brachyurus) is an endangered species in Brazil. The ecology and behaviour of this species were investigated by a survey of the literature and the field study of 26 wolves in São Paulo State which were marked with ear-tags and radio-collars. The animals are territorial and monogamous, and give birth to 2 or 3 young once a year after an average 63 days gestation. Maned wolves inhabit open areas and have omnivorous feeding habits. Parasites of captive animals are reviewed. Several common helminths (including Dirofilaria, Ancylostoma, Uncinaria, Physaloptera, Toxocara, Trichuris, Capillaria, Diphyllobothrium, Spirometra and Taenia) have been recorded from maned wolves but the giant kidney worm, Dioctophyme renale, which was introduced into South America by hunting dogs from Europe, has been responsible for most deaths in captive animals.
