Chrysocyon Brachyurus

The maned wolf (Chrysocyon brachyurus, Illiger 1815) is the largest canid in South America. The objective of this work is to present a new border registry of Chrysocyon brachyurus, in the Department of Gualeguay, Province of Entre Ríos (32°59'51.78''S, 59°30'59.12''W); validate its membership in that taxon through the use of the COI molecular marker and review and comment on recent reports of specimens recorded further south of the known range of the species in a conservation context.

Abstract: Maned Wolf (Chrysocyon brachyurus) is considered one of the largest and most beautiful canids in South America, inhabits the Cerrado biome, and presents nocturnal habits, especially during the twilight period. It is in danger of extinction, mainly due to anthropic activity in its habitat. What certainly raises the importance of studying and better understanding its biology. The mammalian Facial Nerve is the seventh cranial pair and controls the functions of facial expression muscles and others. Once the anatomical descriptions of this canid are scarce, this paper aimed to describe the anatomy of Facial n. in Maned Wolf and correlate it with that of domestic canids, a phylogenetically close species whose anatomy is well known. For this research, four adult specimens were used, whose carcasses were collected along highways in southeastern Goiás State - Brazil (SISBIO 37072-2), or donated by the Wildlife Screening Center (CETAS) in Catalão - Goiás State. The specimens were fixed in a 10% aqueous formalin solution and stored in the same solution. Dissection was performed by macroscopic anatomical methods. The research was carried out with a favorable opinion of the Animal Use Ethics Committee (CEUA) of the Federal University of Uberlândia (UFU) (under n° 067/12). Anatomical preparations of post-mortem Maned Wolf did not reveal the presence of Caudal Auricular, Internal Auricular, nor Stylohyoid n.. Small ramifications of Facial n. can be considered as collateral branches. The Facial n. emerged as a single trunk, Facial n. Trunk, which branches into Auriculopalpebral, Dorsal Buccal, and Ventral Buccal n..

O objetivo deste estudo foi descrever a anatomia da artéria femoral em canídeos selvagens, como o cachorro do mato (Cerdocyon thous), a raposa do campo (Lycalopex vetulus) e o lobo-guará (Chrysocyon brachyurus). Foram utilizados dois espécimes de cada grupo canídeo. Solução de látex vermelha foi injetada no sistema arterial dos animais, que foram então fixados em solução aquosa de formaldeído a 10% e dissecados seguindo as técnicas rotineiras da anatomia macroscópica. Nos três grupos canídeos, o padrão arterial foi semelhante ao descrito para canídeos domésticos, em que a artéria femoral profunda origina da artéria ilíaca externa, ainda na cavidade abdominal, e envia seu primeiro ramo, a artéria femoral circunflexa lateral. Alguns ramos musculares, uma ou duas artérias femorais caudais e os ramos terminais - a artéria genicular descendente, a artéria safena e a artéria poplítea - são originários da artéria femoral. O padrão de origem desses vasos também mostra semelhanças com as de canídeos domésticos, às vezes formando troncos e ocasionalmente originando individualmente. Assim, pode-se concluir que o padrão anatômico da artéria femoral e seus ramos em canídeos selvagens mostra semelhanças com a dos canídeos domésticos, mas variações inerentes em cada espécie também estão presentes.

Chrysocyon Brachyurus

The maned wolf (Chrysocyon brachyurus; Carnivora, Canidae) is the South America's largest canid, typically occurring in open areas of Cerrado, Chaco and Pampa. Its geographical distribution is historically limited to the north by the Amazon forest, and to the northeast by the Caatinga and Atlantic Forest biomes. However, recent studies have reported that its occurrence has recently been expanded to the boundaries of its distribution range. In this study, we presented 22 records of the maned wolf for the Amazon biome, including six records from gray literature, six records of scientific articles from indexed journals and 10 new records, expanding the northwest limit of its geographical range in 51,178.78 km². The presence of the maned wolf in protected and unprotected areas of the Amazon biome, as reported in this study, can play a complementary role in the conservation of species, since its historically boundaries are becoming increasingly permeable.
