| We investigated abundance and activity patterns of the margay (Leopardus wiedii) via remote camera-trapping at Wildsumaco Wildlife Sanctuary, a new preserve located near Sumaco National Park, in the eastern Andean foothills of Ecuador. We recorded 85 capture events and ten individuals, including one juvenile, over a total of 3220 camera-trap nights. Activity was mostly nocturnal and we found no difference in abundance between primary and secondary forest. Our capture rate (2.64 captures/100 camera-trap nights) indicates a high abundance of margays in the region. The site lies within a matrix of agricultural lands and the high abundance and seasonal occurrence data seem to suggest that while one or two females may occupy the area permanently, most margays... |

| Descriptive anatomical studies of wild animals are fundamental, since they provide subsidies for the elaboration of more adequate techniques of sustained management, contributing to the preservation of species threatened with extinction. Thus, the aim of the study is to anatomically describe the salivary glands: parotid, mandibular and sublingual of the crab-eating-fox (Cerdocyon thous). For this purpose, three carcasses of crab-eating-fox donated by Ibama were used. The animals were fixed with 10% aqueous formaldehyde solution, dissected, analyzed descriptively and photographed. It was found that the parotid gland of the crab-eating-fox is located caudally to the branch of the mandible, in the rostroventral margin of the auricular cartilage. The... |

| Because extinctions are not random across taxa, it is important for conservation biologists to identify the traits that make some species more vulnerable. Factors associated with vulnerability include small geographical ranges, low densities, high trophic level, "slow" life histories, body size, and tolerance to altered habitats. In this study we examined the relationship of body size, reproductive output, longevity, and extinction risk for carnivores occurring in Brazil. We used generalized linear models analyses on phylogenetically independent contrasts to test the effect of body size alone, and the combined effect of body size, litter size and longevity on extinction risk. Body size appeared in the two best models according to the selection criteria... |

| We examined 96 museum specimens belonging to 14 species of Carnivora from the Mexican State of Puebla. In addition, four species were documented based on literature records and by indirect evidence. The carnivorous mammals of Puebla belong to 5 families, 18 genera, 18 species and 23 subspecies. Eight of these 23 taxa are reported herein for the first time from the state of Puebla. Of the 18 species, Herpailurus yagouaroundi, Lontra longicaudis, Taxidea taxus, and Galictis vittata are considered by Norma Oficial Mexicana as threatened species, Leopardus wiedii and Eira barbara in danger of extinction, and Potos flavus is under special protection. We found Lynx rufus, Canis latrans, Taxidea taxus, and Bassariscus astutus were found only in the Nearctic... |

| Little is known about the use of feces in scent marking by small wildcats. We analyzed the characteristics of 357 Geoffroy's cat, Leopardus geoffroyi, defecation sites in five protected areas of Argentina. Defecation sites were mainly found in trees (47.6%) or on the ground (38.1%), and the frequency of occurrence of the types of sites differed between areas. Almost half (47.3%) of defecation sites were latrines, with 6.1 ± 3.6 (mean ± SD) feces each. Geoffroy's cats were flexible in the choice of defecation sites, but mainly deposited feces in latrines located in conspicuous sites. These results suggest that Geoffroy's cats use feces in olfactory/visual communication. |

| This study identifies the food habits of the margay, Leopardus wiedii (Schinz, 1821), and the jaguarundi, Puma yagouaroundi (É. Geoffroy Saint-Hilare, 1803), in the Vale do Rio Doce Natural Reserve and in the Sooretama Biological Reserve, Espírito Santo, Brazil. We determined the diet of both species by the analysis of scats. Fecal samples were collected from April 1995 to September 2000 and identified based on the presence of hairs that were ingested during self-grooming. Scats were oven-dried and washed on a sieve, and the screened material was identified using a reference collection. Of the 59 fecal samples examined, 30 were confirmed to be from the margay and nine of them from the jaguarundi. Mammals were the most consumed items in the diet of the... |

| This study details for the first time the food habits of the culpeo or Andean fox (Lycalopex culpaeus) in high areas of the Ecuadorian Andes during a complete annual cycle. Our objective was to identify prey species, calculate their contribution to diet and test for temporal variation. In total, 304 Andean fox scats were collected within the Podocarpus National Park (Loja province, southern Ecuador). By analysing the content of scats 413 prey items were identified and classified into eight prey groups. Subsequently, the frequency of occurrence (FO) for each prey group was calculated per month together with the relative contribution of estimated consumed biomass (CB). In addition, the Shannon-Wiener’s index was calculated as a measurement of monthly diet... |

| La identificación precisa de heces de carnívoros silvestres es importante para describir sus hábitos alimenticios, sobre todo en aquellas especies elusivas o en riesgo. Sin embargo Identificar las heces de especies de carnívoros simpátricos no es una tarea sencilla. Por ello, las técnicas moleculares, son herramientas que brindan mayor precisión en la identificación de heces. El análisis de hábitos alimenticios aporta información valiosa para entender la estructura poblacional de los depredadores y sus presas, así como su importancia ecológica para generar estrategias de manejo y conservación de carnívoros y sus presas. Los objetivos de este estudio fueron identificar las heces de carnívoros extrayendo ADN mitocondrial de estas y amplificando un fragmento... |

| ABSTRACT The aim of the present study was to isolate Clostridium perfringens and C. difficile in crab-eating fox (Cerdocyon thous) from Northeastern Brazil. Stool samples of 18 captive crab-eating foxes from four states of Northeastern Brazil (Alagoas, Bahia, Paraíba e Pernambuco) were collected and subjected to C. perfringens and C. difficile isolation. Suggestive colonies of C. perfringens were then analyzed for genes encoding the major C. perfringens toxins (alpha, beta, epsilon and iota), beta-2 toxin (cpb2), enterotoxin (cpe), and NetB- (netB) and NetF- (netF) encoding genes. C. difficile strains were analyzed by multiplex-PCR for a housekeeping gene (tpi), toxins A (tcdA) and B (tcdB) and a binary toxin gene (cdtB). Unthawed aliquots of stool samples... |

| The crab-eating fox (Cerdocyon thous) exhibits a very generalist habit and fruits compose a large proportion of its diet. However, few studies evaluated the importance of this animal as seed disperser. In the Restinga forest, in the Atlantic forest of Brazil, C. thous consumes fruits of Eugenia umbelliflora, a Myrtaceae species, which is dispersed chiefly by birds. This study evaluated the effects of gut transit on seed germination, and size selection of E. umbelliflora fruits by the crab-eating fox. We did not find differences on germination rates between seeds dispersed by foxes and control ones, but seeds dispersed by foxes germinated faster, which may be important for plant recruitment. Seeds consumed by C. thous were smaller than those available on... |
