abstract
| - This mammal is found in open and semi-open habitats, especially grasslands with scattered bushes and trees, in south, central-west, and southeastern Brazil (Mato Grosso, Mato Grosso do Sul, Minas Gerais, Goiás, São Paulo, Federal District, and recently, Rio Grande do Sul), Paraguay, northern Argentina, Bolivia east and north of the Andes, and far southeastern Peru (Pampas del Heath only). It is very rare in Uruguay, possibly being displaced completely through loss of habitat. IUCN lists it as near threatened, while it is considered a vulnerable species by the Brazilian government (IBAMA). It is known locally as aguará guazú (meaning "large fox" in the Guaranilanguage), or "kalak" by the Toba, lobo de crin, lobo de los esteros, or lobo colorado, and as lobo-guará in Brazil. It also is called borochi in Bolivia.

It also is called borochi in Bolivia. The maned wolf bears minor similarities to the red fox, although it belongs to a different genus. The average adult weighs 23 kg (51 lb) and stands 90 cm (35 in) tall at the shoulder, has a head-body length of 100 cm (39 in) with the tail adding another 45 cm (18 in). Its ears are large and long (7 inches). The maned wolf is the tallest of the wild canids; its long legs are likely an adaptation to the tall grasslands of its native habitat. Fur of the maned wolf may be reddish brown to golden orange on the sides with long, black legs, and a distinctive black mane. The coat is marked further with a whitish tuft at the tip of the tail and a white "bib" beneath the throat. The mane is erectile, and typically, is used to enlarge the wolf's profile when threatened or when displaying aggression. The maned wolf also is known for the distinctive odor of its territory markings, which has earned it the nickname "skunk wolf." Unlike other large canids (such as the gray wolf, the African hunting dog, or the dhole) the maned wolf does not form packs. It hunts alone, usually between sundown and midnight. Maned wolves rotate their large ears to listen for prey animals in the grass. They tap the ground with a front foot to flush out the prey and pounce to catch it. It kills its prey by biting on the neck or back, and shaking the prey violently if necessary. Monogamous pairs may defend a shared territory of approximately 30 km2 (12 sq mi), although outside of mating, the individuals may meet seldom. The territory is crisscrossed by paths that the maned wolves create as they patrol at night. Several adults may congregate in the presence of a plentiful food source, for example, a fire-cleared patch of grassland that would leave small vertebrate prey exposed while foraging. Both female and male maned wolves use their urine to communicate, e.g. to mark their hunting paths or the places where they have buried hunted prey. The urine has a very distinctive odor, which some people liken to hops or cannabis. The responsible substance very likely is a pyrazine, which also occurs in both plants. At the Rotterdam Zoo, this smell once set the police on a hunt for cannabis smokers. The preferred habitat of the maned wolf include grasslands, scrub prairies, and forests. Their mating season ranges from November to April. Gestation lasts 60 to 65 days and a litter may have from two to six black-furred pups, each weighing approximately 450 g (16 oz). Pups are fully grown when one year old. During that first year, the pups are known to rely on their parents for food. The maned wolf is omnivorous. It specializes in small and medium-sized prey, including small mammals (typically rodents and rabbits), birds, and even fish, but a large portion of its diet (more than 50%, according to some studies) is vegetable matter, including sugarcane, tubers, and fruit (especially the wolf apple, Solanum lycocarpum, a tomato-like fruit). Traditionally, captive maned wolves were fed meat-heavy diets, but that caused them to develop bladder stones.

- Description The Maned Wolf (Chrysocyon brachyurus) is the largest canid of South America, resembling a big fox with reddish fur. It is called lobo-guará (“Guará Wolf”) in Portuguese, aguara guazú (“Big Fox”) in Guarani, and lobo de crin (“Maned Wolf”) in Spanish. It was improperly called Canis jubatus (“Maned Dog”) in some 19th century publications. The distribution includes southern Brazil, Paraguay, and Bolivia east of the Andes[1]. It is an endangered species, and its range once included Uruguay and northern Argentina, although IUCN lists it as “lower risk”. It is the only species in the genus Chrysocyon. The Maned Wolf has often been described as “a Red Fox on stilts” due to its similar coloration and overall appearance, though it is much larger than a Red Fox and belongs to a different genus. The adult animal stands almost 1 m (3 ft) tall at the shoulder, and weighs 20 to 25 kg. (50 to 55 lb)[2]. Its fur is reddish brown to golden orange on the sides, with long, black legs and a distinctive black mane. The coat is further marked with a whitish tuft at the tip of the tail and a white “bib” beneath the throat. The mane is erectile, and is typically used to enlarge the wolf's profile when threatened or when displaying aggression. Hunting and Territoriality Unlike other large canids (such as Wolves, African Hunting Dogs, Dholes) the Maned Wolf does not form packs.[2] It hunts alone, usually between sundown and midnight. It kills its animal prey by biting on the neck or back, and shaking it violently if necessary [3]. Monogamous pairs may defend a shared territory of about 30 square km, though the wolves themselves may seldom meet, outside of mating. The territory is criscrossed by paths that the wolves create as they patrol at night. Several adults may congregate in the presence of a plentiful food source; a fire-cleared patch of grassland, for example, which would leave small vertebrate prey exposed to foraging wolves. Maned Wolves, both male and female, use their urine to communicate, e.g. to mark their hunting paths, or the places where they have buried hunted prey [3]. The urine has a very distinctive smell, which some people liken to hops or cannabis. The responsible substance is very likely a pyrazine, which occurs in both plants. (In the Rotterdam Zoo, this smell once set the police on a hunt for cannabis smokers[4].) Reproduction The mating season ranges from November to February. Gestation lasts 70 to 75 days, and a litter may have up to 2-6 pups, each weighing about 450 g (1 lb) [3]. Diet Maned Wolves specialize in small and medium-sized prey, including small animals (rodents, hares), birds, and even fish [5] [3]. A large fraction of their diet (over 50%, according to some studies) is vegetable matter, including sugarcane, tubers, and fruit—especially Wolf Apples, the tomato-like fruit of the Lobeira (Solanum lycocarpum)[6]. Captive maned wolves were traditionally fed meat-heavy diets and developed kidney stones. Zoo diets now feature fruits and vegetables, as well as meat and dog chow. Relations with other species Maned Wolves participate in symbiotic relationships with the plants that they feed on, as they carry the seeds of various plants, and often defecate on the nests of the leaf-cutting ant. 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.[7]. The wolf is particularly susceptible to renal nematode infections, a potentially fatal parasite. The Maned Wolf is not a true, common prey species for any other predator, though it may be attacked or killed by feral domestic dogs. The puma is a potential competitor. Relation with Human The Maned Wolf is said to be a potential chicken thief; it was once also considered a threat to cattle and sheep, though this is now known to be false. In Brazil, the animal was historically hunted down for some body parts, notably the eyes, that were believed to be good luck charms. However, as they are now classified as endangered by the Brazilian government, they are afforded protection from poachers. Wolves are also endangered by habitat loss and being run over by cars, though there are some positive benefits[citation needed] from the conversion of forest into grassland by humans. Wolves risk both physical harm and catching diseases from domestic dogs. The Maned Wolf is shy and flees when alarmed, and it poses little direct threat to man. Maned Wolves are well represented in captivity, and have been bred successfully at a number of zoos like in Argentina. Taxonomy The Maned Wolf is not closely related to any other canid. It is apparently a survivor from the Pleistocene fauna of large South American mammals; its closest relatives seem to be the dogs and wolves (genus Canis). Previously, some authorities placed it with the various South American foxes, others with the Bush Dog.
