1. Avaliação do sistema estomatognático e de sincrânios de lobo-guará (Chrysocyon brachyurus) em vida livre e cativeiro / Oral and skull evaluation of captive and wildlife maned wolves (Chrysocyon brachyurus)
The maned wolf, Chrysocyon brachyurus, is the largest wild canid inhabiting South America, specially areas with tall grass, fence and bush forest. They are omnivorous and their most important dietary components are small mammals, reptiles, insects, forage plants and fruits. There are few studies about oral diseases in free-ranging and captive maned wolves. T

2. The stimulus to foraging as an environmental enrichment factor for maned wolves / O estímulo ao forrageamento como fator de enriquecimento ambiental para lobos guarás: efeitos comportamentais e hormonais
O lobo guará (Chrysocyon brachyurus), uma espécie vulnerável, tem apresentado problemas reprodutivos e de bem-estar em cativeiro. Buscando técnicas eficazes para melhorar os níveis de bem estar destes animais, e dando continuidade a estudo anterior, procurou-se investigar os efeitos da dispersão do alimento e variáveis possivelmente relacionadas à va

3. Comparison of serum hormone levels of captive and free-living maned wolves Chrysocyon brachyurus
Serum hormone levels were compared between captive and free-living maned wolves and seasonal variations of sex hormones were studied. Blood samples were collected from 16 male and 26 female adult animals from Brazilian zoos, and from 30 male and 24 female free-living adults to determine serum progesterone and testosterone by radioimmunoassay. Serum testoster

4. Diversidade genética e conservação do lobo-guará, Chrysocyon brachyurus, em áreas protegidas do Distrito Federal
I evaluated the genetic diversity of a maned wolf population (Carnivora, Canidae, Chrysocyon brachyurus) in the Distrito Federal DF, Brazil. The maned wolf distribution is intimately associated with the distribution of the Cerrado biome. The species suffers the effects of habitat lost and is considered vulnerable to extinction in the Brazilian species red li

5. Serologic evidence of Leishmania infection in free-ranging wild and domestic canids around a Brazilian National Park
Transmission of disease between wildlife, domestic animals, and humans is of great concern to conservation issues and public health. Here we report on the prevalence of anti-Leishmania sp. antibodies in 21 wild canids (7 Chrysocyon brachyurus, 12 Cerdocyon thous, and 2 Lycalopex vetulus) and 74 free domestic dogs (Canis familiaris) sampled around the Serra d

6. Infecção por Toxoplasma gondii e Neospora caninum em cães e lobos-guará: soroepidemiologia e imunodiagnóstico / Infecção por Toxoplasma gondii e Neospora caninum em cães e lobos-guará: soroepidemiologia e imunodiagnóstico
Toxoplasma gondii and Neospora caninum are two closely related apicomplexan parasites, even though phylogenetic, ultrastructural, antigenic and biological differences have been already described. Seroepidemiological studies have demonstrated that T. gondii infection is often in domestic and sylvatic canids, whereas N. caninum infection is less common, but it

7. Core area and centre of activity of maned wolves, Chrysocyon brachyurus (Illiger) (Mammalia, Canidae), submitted to supplemental feeding
A área central e o centro de atividade de lobos-guará, Chrysocyon brachyurus (Illiger, 1815), foram determinados através de seus vestígios (fezes, pegadas e pêlos) em uma reserva natural particular, onde esses animais estão sujeitos à alimentação artificial e sofrem influência de atividades turísticas. No total, foram registrados 465 vestígios, s

8. Diet adjustments of maned wolves, Chrysocyon brachyurus (Illiger) (Mammalia, Canidae), subjected to supplemental feeding in a private natural reserve, Southeastern Brazil
From the analysis of 230 scats, the diet of the maned wolves, Chrysocyon brachyurus (Illiger, 1815), was determined in a private natural reserve in southeastern Brazil in which ecotourism activities are developed and the animals are deliberately fed bovine meat. A total of 569 occurrences of food items were recorded, of which 56.8% were of animal origin and

9. Epidemiologia e genética populacional de lobos guarás, Chrysocyon brachyurus, (ILLIGER 1815) (CARNIVORA, CANIDAE) no nordeste do estado de São Paulo
This study was accomplished in the northeastern area of the state of São Paulo, obtaining biological material of maned wolves for the epidemiology (parasitic diseases) and populacional genetic study. The occurrences of deaths were also verified and the relationships between the farmers and wolves were appraised. In the studies of parasitic diseases, infesta

10. Biologia e conservação do lobo-guara na Estação Ecologica de Aguas Emendadas, DF
The maned wolf (Chrysocyon brachyurus) it is the largest canid of South Arnerica. Characteristic of open habitats, the species is threatened with the transformation of the fields in agricultural are as and, today, in spite of the wide distribution, they have to work with the difficulties of living in fragmented areas. Most of the Conservation Units of the Ce

11. Telemetria convencional e via satélite na determinação da área de vida de três espécies de carnívoros da região nordeste do Estado de São Paulo.
The main objectives of this work were to determine diet, and home range of three mammal carnivore species, which are endangered of extinction in São Paulo State: the maned wolf ((Chrysocyon brachyurus, Illiger 1815), cougar (Puma concolor, Linnaeus 1771), and ocelot (Felis pardalis, Linnaeus 1758); and to draw strategies for landscape planning in order to i
