about maned wolf:

Guara wolf From Wikipedia, the free encyclopedia How to read a taxonomy infoxoxy-maned wolf [1] Occurrence: Pleistocene - Recent Maned wolf in the Serra da Canastra National Park Maned wolf in the Serra da Canastra National Park conservation state Almost threatened Almost threatened (IUCN 3.1) [2] Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Canidae Genre: Chrysocyon Smith, 1839 Species: C. brachyurus Binomial name Chrysocyon brachyurus Illiger, 1815 Type species Canis jubatus Desmarest, 1820 Geographic distribution Maned Wolf range.png Synonyms [3] Canis brachyurus Illiger, 1811 Canis campestris Wied-Neuwied, 1826 Canis isodactylus Ameghino, 1909 Canis jubatus Desmarest, 1820 Vulpes cankerosa Oken, 1816 The maned wolf (scientific name: Chrysocyon brachyurus) is a species of canid endemic to South America and the only member of the genus Chrysocyon. Probably the closest living species is the vinegar dog (Speothos venaticus). It occurs in savannas and open areas in central Brazil, Paraguay, Argentina and Bolivia, being a typical animal of the Cerrado. It was extinct in part from its occurrence to the south, but it must still occur in Uruguay. On July 29, 2020 the maned wolf was chosen to symbolize the two hundred reais bill.

It is the largest canid in South America, reaching between 20 and 30 kg in weight and up to 90 cm at the height of the withers. Its long, slender legs and dense reddish coat give it an unmistakable appearance. The maned wolf is adapted to the open environments of the South American savannas, being a twilight and omnivorous animal, with an important role in the dispersion of seeds of fruits of the cerrado, mainly the lobeira (Solanum lycocarpum). Lonely, the territories are divided between a couple, who are in the period of the female's estrus. These territories are quite wide, and may have an area of ​​up to 123 km². Communication takes place mainly through scent marking, but vocalizations similar to barking also occur. Gestation lasts up to 65 days, with black newborns weighing between 340 and 430 g.

Despite not being considered in danger of extinction by the IUCN, all the countries in which it occurs classify it in some degree of threat, although the real situation of the populations is not known. It is estimated that there are about 23 thousand animals in the wild, being a popular animal in all zoos. It is threatened mainly because of the destruction of the cerrado to expand agriculture, pedestrian accidents, hunting and diseases caused by domestic dogs. However, it is adaptable and tolerant of changes caused by humans. The maned wolf currently occurs in areas of Atlantic Forest already deforested, where it did not originally occur.

Some communities carry superstitions about the maned wolf and may even harbor a certain aversion to the animal. But in general, the maned wolf provokes sympathy in humans and is therefore used as a flag species in the conservation of the Cerrado.

[4] [5] The term wolf originates from the Latin lupus. [4] Guará and aguará originated from the Tupi-Guarani agoa'rá, "down hair". [6] Aguaraçu came from the term for "guará grande". [4] Tupi-Guarani names of origin are more common in Argentina and Paraguay (aguará guazú), but other Spanish-speaking countries have other names like boroche in Bolivia and wolf of crin in Peru. [7] Lobo de crin (in Spanish) and maned wolf (in English) are allusions to the mane of the nape of the neck. [7]

Taxonomy and evolution

It is one of the endemic canids of South America. Phylogenetic relationships of South American canids. [8]

Chrysocyon brachyurus - maned wolf

Speothos venaticus - vinegar dog

Atelocynus microtis - short-eared bush dog

Cerdocyon thous - bush dog

Lycalopex genus - South American foxes

Phylogeny inferred from mitochondrial and nuclear DNA data. The species was described in 1815, by Johann Karl Wilhelm Illiger, initially as Canis brachyurus. [3] Lorenz Oken classified it as Vulpes cancosa, and only in 1839, Charles Hamilton Smith described the genus Chrysocyon. [3] Later, other authors considered him to be a member of the genus Canis. [3]

Despite having belonged to the genera Canis and Vulpes, due to their morphological similarities, the maned wolf is not closely related to these genera. [9] Molecular studies have shown no relationship between the Chrysocyon genus and these canids. [8] [10] The maned wolf is one of the endemic canids of South America, along with the bush dog (Cerdocyon thous ), the vinegar dog (Speothus venaticus) and the genus Lycalopex. [8] Such a group is monophyletic according to genetic studies, but morphological studies include Nyctereutes procyonoides, who is originally from Asia. [8]A study comparing the brain anatomy of several canids, published in 2003, placed the maned wolf as akin to the falkland fox (Dusicyon australis) and the genus Lycalopex (considered by the authors as Pseudalopex). [11] Molecular studies corroborate that the maned wolf has a unique common ancestor with the falkland fox, which lived approximately 6 million years ago. [12] [13]However, recent genetic studies place the maned wolf as the closest phylogenetically to the vinegar dog (Speothos venaticus), forming a clade that is a sister group to another to which all other South American canids belong, such as the canine dog. short-eared bush (Atelocynus microtis), the bush dog (Cerdocyon thous) and the genus Lycalopex. [8] [10] This clade diverged from other South American canids about 4.2 million years ago, and the Chrysocyon and Speothos genera diverged about 3 million years ago. [8]Not many maned wolf fossils are known and those that were discovered originate from the Holocene and the Upper Pleistocene, unearthed in the Brazilian plateau, indicating that the species also evolved only in the open areas of Central Brazil. [14] Nor are subspecies recognized. [15]Geographic distribution and habitatThe Cerrado is the main habitat of the maned wolf. The maned wolf is an endemic canid from South America and inhabits the grasslands and thickets of the center of that continent. Its geographic distribution extends from the mouth of the Parnaíba River, in the Northeast of Brazil, through the lowlands of Bolivia, east of the Pampas del Heath, in Peru and the Paraguayan chaco, to Rio Grande do Sul. [3] Evidence of the maned wolf's presence in Argentina can be found up to Parallel 30, with recent sightings in Santiago del Estero. [2] Probably the maned wolf still occurs in Uruguay, given that a specimen was spotted in 1990, but since then there has been no record of the species in the country. [2]It is a fact that the maned wolf has disappeared in many regions at the southern limits of its geographical distribution, occurring almost only up to the border of Rio Grande do Sul with Uruguay. [16] Interestingly, the deforestation of the Atlantic Forest in the southeastern and eastern regions of Brazil favored the expansion of its geographic distribution to areas where it did not previously inhabit. [16] For this reason, records in Atlantic Forest areas in Paraná, São Paulo, Rio de Janeiro and Minas Gerais have increased in recent years. [5] In the Pantanal the maned wolf occurs in highlands in the upper Paraguay, but avoids the lowlands of the Pantanal plain. [5] There are sporadic records of the species in transition areas between the Cerrado and the Amazon and the Caatinga. [5] The species can occur above 1,500 meters in altitude. [5]The maned wolf habitat is mainly characterized by open fields, with shrub vegetation and forest areas with open canopy, being a typical animal of the Cerrado. [15] It can also be found in areas that experience periodic flooding and man-made fields. [15] The maned wolf prefers environments with a low amount of shrubs and sparse vegetation. [15] More closed areas are used for rest during the day, especially in regions that have been greatly altered anthropically. [17] In these altered areas it can be seen in cultivated fields, Eucalyptus plantations and even in suburban areas. [18] Although the species can occur in anthropic environments, further studies are needed to quantify the degree of tolerance of the maned wolf to agricultural activities, but some authors suggest the preference for areas modified by man as opposed to well-preserved forest areas. [5] [15]DescriptionThe skull is similar to that of the wolf and the coyote. It is the largest canid in South America, reaching between 95 and 115 cm in length, with a tail measuring between 38 and 50 cm in length and reaching up to 90 cm at the height of the withers. [15] It weighs between 20.5 and 30 kg, with no significant differences in the weight of males and females. [15] It is an animal difficult to confuse with other South American canids, because of its long and thin legs, dense reddish coat and large ears. [15] The species' slender shape is probably an adaptation to displacement in open areas covered by grasses. [3]It is unmistakable among South American canids, being the largest among them. The body coat varies from golden red to orange and the hairs on the back of the neck and feet are black, with no undercoat in the coat. [3] The lower part of the jaw and the tip of the tail are white. [3] The hairs are long, reaching up to 8 cm in length along the body, forming a type of mane on the animal's neck. [7] There is almost no variation in the color of the coat, and it is not possible to identify individuals or sex from hair color, although an entirely black individual has already been recorded in northern Minas Gerais. [7] [19]The shape of the head looks like that of a fox. The snout is slender and the ears are large. [3] However, the skull is similar to that of the wolf (Canis lupus) and the coyote (Canis latrans). [3] The skull also has a prominent sagittal crest. The butcher tooth is reduced, the upper incisors small and the canines long. [3] Like the other canids, it has 42 teeth with the following dental formula: {\ displaystyle {\ tfrac {3.1.4.2} {3.1.4.3}} \ times 2 = 42} \ tfrac {3.1.4.2} {3.1.4.3} \ times 2 = 42 [20] Similar to the vinegar dog (Speothos venaticus), the maned wolf's rhyme extends to the upper lip, but the vibrissae are longer. [3]The maned wolf's footprints are similar to those of the dog, but have the pads disproportionately small when compared to the digits of the digits, which are wide open. [21] [22] The dog has foot pads up to 3 times larger than the maned wolf's footprints. [22] These pillows are triangular in shape. [22] The front footprints are between 7 and 9 cm long and 5.5 and 7 cm wide, and those on the back legs are between 6.5 and 9 cm long and 6.5 to 8.5 cm wide. [22 ] A characteristic that differentiates the maned wolf's footprints from that of other South American canids is the proximal union of the third and fourth digits. [3]Geneticame n the maned wolf has 38 chromosomes, with a karyotype similar to that of other canids. [3] Genetic diversity suggests that 15,000 years ago the species suffered a reduction in its diversity, called the bottleneck effect. Even so, this genetic diversity is greater than that of other canids. [5]average 0.7 seconds in 2 to 4 second intervals, a sequence that is repeated for up to 23 times. [7] Both males and females vocalize. [7] They tend to vocalize more at night, when they can be heard from several meters away. [35] Despite being associated with territoriality, vocalizations are more frequent among young people from the same territory, suggesting that they are only a sign for contact over great distances between known individuals and not for the defense of territory. [35]Direct social interactions are rare and maned wolves seem to avoid each other. [7] Agonistic encounters are rare but occur mainly between males, and have not been seen among females. [32] This results in almost no overlap in the male territories. [32]

Reproduction and life cycle

The puppies are born weighing between 340 and 430 g and have a reddish coat after the tenth week As in the diet, most of the data on the maned wolf's estrus and reproductive cycle comes from animals in captivity, mainly on the endocrinology of reproduction. [33] However, studies of animals in freedom have found that hormonal changes follow the same pattern of variation as animals in captivity. [33] At first females spontaneously ovulate, but some authors suggest that the presence of a male is important for estrus induction. [33]

Captive animals in the northern hemisphere breed between October and February and in the southern hemisphere between August and October. This indicates that the photoperiod has an important role in the reproduction of the maned wolf, mainly due to the production of semen. [3] [33] Usually estrus occurs annually [3] and the amount of sperm produced by the maned wolf is less when compared to that of other canids. [33]

Copulations take place during the 4-day period of estrus and are followed by up to 15 minutes of copulatory engagement. [3] The courtship behavior is no different from that of other canids, characterized by frequent approximations and anogenital investigation. [26]

The gestation lasts about 65 days, being born between 2 and 5 puppies, but 7 puppies have already been registered. [3] Births in May have already been observed in the Serra da Canastra, but captivity data suggest that births are concentrated between June and September. [5] The few data available on reproduction in the wild show that the maned wolf reproduces with difficulty and the mortality of young is high. Females can stay up to 2 years without reproducing. [33]

In captivity, reproduction is even more difficult, especially in temperate countries in the northern hemisphere. [33] The puppies are born weighing between 340 and 430 grams, black and changing to a reddish color after the tenth week. [3] The eyes open at about 9 days of age. [3] They are breastfed up to 4 months and fed by their parents through regurgitation until 10 months, starting at the 3rd week of age. [25] [26] At three months of age the puppies accompany the mother while she forages. [25] Parental care is shared between male and female, but females do this more often. [25] Data on male parental care have been collected from captive animals, and little is known about whether this occurs frequently in wild animals. [26] Sexual maturity is reached at 1 year of age and after that age they leave the territory in which they were born. [26]
