Few studies have documented fine-scale movements of ungulate species, including white-tailed deer(Odocoileus virginianus), despite the advent of global positioning system (GPS) technology incorporated into tracking devices. We collected fine-scale temporal location estimates (i.e., 15 min/relocation attempt) from 17 female and 15 male white-tailed deer over 7 years and 3 seasons in Oklahoma, USA. Our objectives were to document fine-scale movements of females and males and determine effects of reproductive phase, moon phase, and short-term weather patterns on movements. Female and male movements were primarily crepuscular. Male total daily movements were 20% greater during rut () than postrut (). Female daily movements were greatest during postparturition (), followed by parturition (), and preparturition (). We found moon phase had no effect on daily, nocturnal, and diurnal deer movements and fine-scale temporal weather conditions had an inconsistent influence on deer movement patterns within season. Our data suggest that hourly and daily variation in weather events have minimal impact on movements of white-tailed deer in southern latitudes. Instead, routine crepuscular movements, presumed to maximize thermoregulation and minimize predation risk, appear to be the most important factors influencing movements.

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

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.
