Jaguarundi (Puma yagouaroundi) (Geoffroy, 1803) (Carnivora, Felidae) food habits in a mosaic of Atlantic Rainforest and eucalypt plantations of southeastern Brazil

A dieta de uma população de jaguarundi (Puma yagouaroundi) (Geoffroy, 1803) (Carnivora, Felidae) foi estudada entre novembro de 2000 e novembro de 2001, em 24,9 km² de mosaico de Mata Atlântica secundária e reflorestamento de eucalipto na Serra de Paranapiacaba, São Paulo, Brasil. A análise das 26 amostras fecais e regurgitadas, obtidas em 570.1 km de percurso, indicou o consumo de 19 itens alimentares em um total de 74 ocorrências de presas. Pequenos mamíferos foram os itens mais frequentemente encontrados na dieta (42,5%), seguidos por aves (21%), répteis (14%) e mamíferos de tamanho médio (3%). A porcentagem de ocorrência (PO) sugere que a dieta concentra-se, principalmente, em pequenos roedores (30%) e aves (21%). Foi também registrada a predação sobre serpentes da família Viperidae. A amplitude de nicho alimentar padronizada (Bsta = 0,76) mostra uma dieta generalista, entretanto, os dados sugerem que o jaguarundi consome principalmente pequenos vertebrados (mamíferos, aves ou répteis), sobretudo, espécies terrestres.

Sonographic findings in unilateral hydronephosis in a jaguarundi Puma yagouaroundi - case report

A jaguarundi (Puma yagouaroundi) was sent to the diagnostic imaging sector for an abdominal ultrasound. In the present report, we observed a marked dilation of the left kidney, with anechogenic content and the presence of echogenic lines extending from the capsule towards the center of the kidney, sonographic evidence that indicates the diagnosis of hydronephrosis.

Ecology and conservation of felids in the Brazilian pantanal

Habitat conversion and environmental degradation have reached alarming levels in the Pantanal, endangering all its biodiversity. This scenario is complicated by the fact that the biome relies on only a few protected areas, which combined do not exceed 10% of the territory. Felids, as predators, play a vital role in the maintenance of this ecosystem, but require large areas, have low population densities and, typically, are very sensitive to environmental disturbances. Amolar Mountain Ridge is considered an area of extreme importance and high priority for conservation within the biome. There are four species of felids in this region: the jaguar (Panthera onca), the puma (Puma concolor), the ocelot (Leopardus pardalis), and jaguarundi (Puma yagouaroundi). However, little is known about the ecology of these species in this region or the magnitude of interaction between the communities living around the protected areas and the animals. The goal of this study was to increase our knowledge about these felids and understand how people interact with them in order to contribute to their conservation in the network of parks within Amolar. Camera trapping surveys were carried out in two areas of the network, covering approximately 83,000 hectares, in order to identify the species of mammals occurring in the region, those that may be potential prey for the felids, and to obtain basic ecological data about both felids and prey. In addition, we conducted surveys in three riverside schools in order to assess the knowledge, perceptions and attitudes of schoolchildren regarding the four focal felids, and surveys among the adult population to assess their perceptions and attitudes towards the jaguar. We recorded a total of 33 species of mammals from both study areas. The large cats were cathemeral, reflecting the temporal activity of larger prey, whereas the ocelot was nocturnal, mirroring the activity of smaller prey. Jaguar occupancy was influenced by prey abundance, while puma occupancy was influenced by patch density in drier dense forest. Jaguars and pumas may be competitors over temporal and spatial scales, while no resource overlap was found for ocelots. Overall, both adults and children tended to have negative perceptions about the cats, which were related to the fear of being attacked. To increase awareness about the species and to maximize the effectiveness of protective measures in the network of reserves, it is recommended to develop and implement an Environmental Educational Program in the medium- to long-term in order to minimize the fear of these felids and to counsel locals on the role of felids in the maintenance of the Pantanal’s biodiversity.

The first report of Hepatozoon sp (Apicomplexa : Hepatozoidae) in neotropical felids from Brazil

In order to investigate the occurrence of Hepatozoon infection in Neotropical felids from Brazil, blood from the jugular or cephalic vein was taken from 29 non-domestic felids including ocelot (Leopardus pardalis), little spotted cat (Leopardus tigrinus), margay (Leopardus wiedii), and jaguarondi (Puma yagouaroundi) from the Northeast region of Brazil. Hepatozoon infection was confirmed by light microscopy and molecular techniques. The results showed five naturally infected felids. Partial sequences of the 18S rRNA gene of the Hepatozoon sp. from these felids were further analyzed. Sequences revealed that the isolates found are closely related to Hepatozoon sp. from domestic cats in Spain. Hepatozoon species from Neotropical felids were identified molecularly and characterized for the first time. This is also the first report of Hepatozoon infection in a little spotted cat.

Molecular detection of Cytauxzoon spp. in asymptomatic Brazilian wild captive felids

Cytauxzoon. spp. DNA was detected for the first time in blood samples from asymptomatic Brazilian wild captive felids. In 2606, 72 EDTA blood samples from seven wild felids species: Puma concolor (pinna), Leopardus pardalis (ocelot), Puma yagouaroundi (jaguarundi), Leopardus wiedii (margay), Leopardus tigrinus (little spotted cat), Oncifelis colocolo (pampas cat) and Panthera. onca. (jaguar) were analyzed using polymerase chain reaction to amplify the 18S rRNA gene segment in order to verify the presence of Cytauxzoon spp. DNA. Nine samples were positive: six ocelots, two pumas, and one jaguar. In Brazil, wild felids may be natural reservoirs for Cytauxzoon spp.

Serological survey of Toxoplasma gondii in captive Neotropical felids from Southern Brazil

Toxoplasma gondii is the causative intracellular protozoan of toxoplasmosis in human being and animals. Members of the Felidae family are considered the single definitive host for the infection; both wild and domestic cats are able to excrete oocysts in the environment. Wild cats maintained in captivity may serve as source of infection for other clinically susceptible animals in the same environment. The aim of this study was to determine the frequency of T. gondii IgG antibodies in 57 neotropical felids (1 Leopardus geoffroyi; 3 Puma yagouaroundi; 17 Leopardus wiedii; 22 Leopardus tigrinus; and 14 Leopardus pardalis) kept at the Bela Vista Biological Sanctuary, Itaipu Binacional, Southern Brazil, by the modified agglutination test (MAT) using titer 16 as cut-off point. Seropositivity was observed in 38/57 (66.67%; 95% CI 53.66-77.51%) samples, with higher frequency in ocelots (71.43%). Wild-caught felids were three times more likely to be infected when compared to zoo-born animals (P≤ 0.05) and age of wild-caught animals (P= 0.6892; 95% CI. = 0.7528-1.66) was not significant as a risk factor for the infection, the same occurring with zoo-born animals (P= 0.05; 95% CI. = 0.6267-24.052). These results suggest that, despite efforts to control T. gondii infection in zoo facilities, such as individual pens, hygiene monitoring, veterinary care and pre-frozen meat offered as food, non-domestic felids kept in captivity, particularly the wild-caught specimens, may be invariably exposed to infection due to other environmental sources. © 2010 Elsevier B.V.

Medium and large-sized mammals in a private reserve of natural heritage in the municipality of Jaú, São Paulo, Brazil

Medium and large-sized mammals control invertebrate and vertebrate populations and are important seed dispersers. These animals are losing their territory and living range due to deforestation and the fragmentation of natural areas, particularly in the Atlantic Forest and Cerrado. The Private Reserve of Natural Heritage (PRNH) Amadeu Botelho is isolated from other forest fragments and is thus a wildlife refuge in the region of Jaú, central-western region of state of São Paulo, southeastem Brazil. Animals as such as the puma (Puma concolor), ocelot (Leopardus pardalis) and jaguarundi (Puma yagouaroundi) have been sighted in the reserve by wildlife guards and residents. This reserve, which belongs to “Santo Antônio dos Ipês” farm, is surrounded by several plantations, and is very close to the center of the city of Jaú. In addition to surveying the mammal species in the reserve, this study diagnosed the influence of the farm’s activities and the proximity to the center of the municipality of Jaú on the fauna under study

Distribución y taxonomía de mamíferos (clase mammalia) en el Cerro El Potosí Galeana, Nuevo León, México

El Cerro El Potosí es un área prioritaria para la Comisión Nacional para la Biodiversidad (CONABIO) y un Área Natural Protegida por el estado (Anónimo, 2000), debido a la existencia de una gran diversidad de tipos de vegetación y de especies de importancia fitogeografica o su orografía y altitud (3715 msnm) se considera un área promotora de procesos de especiación, registrándose especies endémicas y relictuales como el caso del Pinus culminicola y Nucifraga columbiana , es una de las montañas más altas del noroeste del país, está enclavada en la Sierra Madre Oriental. Con base en la información previa disponible, se presume que esta área ostente una mayor diversidad de flora y fauna. El objetivo principal fue el análisis de la diversidad y distribución de los mamíferos en los diferentes estratos vegetativos y altitudes dentro de los límites del Cerro El Potosí. Con el propósito de realizar las comparaciones de las diversidades de las especies en forma altitudinal, por vegetación, estacional; Se seleccionó la prueba de Chi-cuadrada para determinar dependencia entre especies y la altitud, tipo de muestreo o tipo de vegetación. Se efectuaron 24 salidas (mensuales) de campo, de noviembre del 2006 a octubre del 2008, de 3 a 4 días por salida. Se registraron 27 especies (14 Familias, 24 géneros, 27 especies, y 14 especies no reportadas previamente). De acuerdo al tipo de vegetación la riqueza se concentro en el bosque de pino seguido por el bosque de encino, las especies se distribuyeron en uno, en dos o más estratos de vegetación (patrones), para los diferentes tipos de vegetación se distribuyeron las especies de Silvilagus floridanus, Thomomys bottae, Peromyscus melanotis, Peromyscus levipes ambiguus, Canis latrans y Lynx rufus. Las especies que sólo se encontraron en un solo tipo de vegetación fueron Bassariscus astutus, Conepatus mesoleucus, Corynorhinus townsendii, Didelphis virginiana, Eptesicus fuscus, Puma yagouaroundi, Lasiurus cinereus, Lasiurus ega, Leptonycteris nivalis, Mustela frenata y Sorex milleri, por lo que se aprecia la diversidad encontrada en el sitio, esto en gran medida por la asociación de la vegetación y la altura marcado por la temperatura reportada para el sitio. Las especies que se localizaron en dos o más estratos o patrones de vegetación fueron Myotis thysanodes, Sciurus alleni, Otospermophilus variegatus, Microtus mexicanus, Urocyon cinereoargenteus, Procyon lotor, Puma concolor, Pecari tajacu y Odocoileus virginianus.
