Los mamíferos domésticos y silvestres cumplen un rol importante en la epidemiología de la leptospirosis. El visón americano Neogale vison es un mustélido introducido en Argentina que podría actuar como portador/reservorio de leptospiras en la región. Nuestro objetivo fue estudiar la presencia de Leptospira spp. en muestras de orina y riñón de vison...

Conservation status revision for the Argentine Red List of Endangered mammals

Se estudiaron algunos aspectos de la ecología espacial de tres especies de roedores sigmodontinos (Oligoryzomys longicaudatus, Abrothrix olivacea y Abrothrix hirta) en el Paraje El Contra del Parque Nacional Lanín (Provincia de Neuquén, Argentina). Los resultados se analizaron en el marco del riesgo de exposición humana al Hantavirus "Andes", agent...

A simultaneous masting of two abundant species in the temperate forests of North-West Argentinean Patagonia occurred in 2013 for the first time ever recorded: the semelparous bamboo grass Chusquea culeou (colihue), dominating the understory, flowered and set seed across 1100 km2 while pehuén (Araucaria araucana), an endemic conifer co-dominating th...

Some aspects of the spatial ecology of three species of sigmodontine rodents (Oligoryzomys longicaudatus, Abrothrix olivacea and Abrothrix hirta) were studied in the Paraje El Contra, Lanín National Park (Province of Neuquén, Argentina), and the results were then analyzed in relation to the risk of human exposure to “Andes” Hantavirus, causative ag...

INTRODUCED MAMMALS IN NEUQUÉN PROVINCE: STATUS AND MANAGEMENT PRIORITIES. Patagonia houses 84 species of native mammals and numerous exotic species. In this study we reviewed the quantity and identity of mammalian species introduced in Neuquén province (NW Patagonia, Argentina) and their present status. We also updated the area invaded by Cervus el...

La caña colihue Chusquea culeou domina el sotobosque de los bosques templados de los Andes australes y tiene una estrategia de reproducción semélpara donde todas las plantas de una región se reproducen simultáneamente cada 60–70 años, produciendo masivamente semillas a gran escala. El Pehuén Araucaria araucana es una conífera endémica también de lo...

En el 2012, en una área de la provincia del Neuquén, se produjo de manera simultánea la floración masiva de Caña colihue (Chusquea culeou) y la semillazón más importante de Pehuén (Araucaria araucana) de los últimos 30 años. Estos eventos combinados generaron una extraordinaria oferta de alimento disponible durante el año 2013 con la consecuente ex...

Oligoryzomys longicaudatus is the main reservoir of Andes virus (AND), which causes hantavirus pulmonary syndrome in Patagonia. The factors associated with the presence of antibodies against AND in this species are unknown. This study used a logistic regression model to analyze which characteristics of O. longicaudatus, captured in northern Argenti...

Oligoryzomys longicaudatus es el principal reservorio del virus Andes Sur (AND) causante del síndrome pulmonar por hantavirus en la Patagonia. Aún se desconoce qué características individuales están asociadas a una mayor presencia de anticuerpos contra AND en esta especie. En este estudio, mediante un modelo de regresión logística evaluamos qué car...

The culpeo fox is the largest native canid in Patagonia. The majority of past studies on culpeo foxes have focused on trophic ecology, population dynamics, natural history, competitive interactions, management, and habitat use. Little work has been done on determining activity patterns of the fox and thus, conclusions regarding culpeo fox activity...

Eligmodontia morgani is one of the most abundant endemic species of arid Patagonian steppe. Most previous studies have focused on systematics and taxonomy and ecological information on this species is scarce. The objectives of this study were to estimate population parameters for E. morgani in the Patagonian steppe ecoregion and to compare them to...

Modifications of natural habitat in peridomestic rural areas could affect original rodent community composition, diversity, and evenness. In zoonoses such as hantavirus pulmonary syndrome, the presence of a diverse community can dilute the impact of the principal reservoir, reducing risk to humans. The goal of this study was to examine rodent commu...

Predatory interactions involving large carnivores and their ungulate prey are increasingly recognized as important in structuring terrestrial communities, but such interactions have seldom been studied in the temperate Neotropics. Here, the large carnivore guild is limited to a single species, the puma Puma concolor, native prey populations have be...

The endangered Andean cat Leopardus jacobita was considered an endemic of the Andes at altitudes above 3,000 m, until it was discovered in the Andean foothills of central Argentina in 2004. We carried out surveys for Andean cats and sympatric small cats in the central Andean foothills and the adjacent Patagonian steppe, and found Andean cats outsid...

The Wild Felid Monitor encourages submission of articles, information and letters on ecology, research, management and conservation of wild felid species, and particularly of those species native to the Western Hemisphere. Preferred length of submissions is about 750 words. Submissions of photos, drawings and charts are encouraged. Electronic submi...

In order to estimate spatial distribution, temporal variation, and prevalence of Andes hantavirus antibody in the rodent community, and especially in Oligoryzomys longicaudatus populations, four different ecosystems were trapped seasonally between spring 2001 and winter 2002 in Neuquen, northwestern Argentinean Patagonia. Five peridomestic settings...
