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.

Based on the finding of remains (tracks, scats, and hairs), an analysis was made of the core area and centre of activity of maned wolves, Chrysocyon brachyurus (Illiger, 1815), living in a private natural reserve in which ecotourism activities are developed and these animals are daily fed bovine meat. A total of 465 samples of remains were recorded. Using the fixed kernel method, the area encompassing all samples recorded was estimated at 25.7 km², yet 50% of all samples were found in an area of only 1.5 km², representing 5.8% of the total area covered. For estimating the core area of the animals, the frequency of occurrence of the samples was determined by superimposing a 50 x 50 m cell grid over a map of the area encompassing all recorded occurrences. Based on the cells containing more than six occurrences, the animals' core area was 0.99 km², which included the place where the animals are fed. The centre of activity was located only 0.50 km from this place. The high negative correlation (r = -0.93, p < 0.05) between the densities of the recorded occurrences and the distances from these to the sanctuary indicates that the core area and centre of activity are conditioned by artificial feeding.

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.
