    Primer registro de Leopardus geoffroyi (Carnivora: Felidae) en la serranía de San Pedro de la ciudad de Cochabamba, Bolivia

    El gato montés (Leopardus geoffroyi) es un felino pequeño sudamericano, que habita en varios países, incluido Bolivia. Aunque la IUCN lo clasifica como Preocupación Menor (LC), en Bolivia es considerado casi Amenazado, principalmente por el comercio ilegal de su piel, pérdida de hábitat y conflictos entre humanos y vida silvestre. Aquí presentamos el primer registro de distribución para la especie en los valles secos interandinos de Cochabamba, más específicamente en la serranía San Pedro, un área verde dentro de la zona metropolitana de la ciudad de Cochabamba. Esta área presenta una presión antrópica enorme, pero contiene aún una porción de vegetación nativa bien conservada. Este registro se obtuvo mediante cámaras trampas como parte de un proyecto de relevamiento de mamíferos terrestres medianos y pequeños. Además, se evidenció algunas amenazas directas para la especie como la presencia de gatos, perros domésticos y ganado ovino y caprino. A pesar de la alta presión antrópica y la cercanía a zonas turísticas, el área presenta potencial para la conservación del gato montés y otras especies silvestres. Estos registros destacan la importancia de proteger fragmentos de vegetación nativa y la necesidad de ampliar las acciones de conservación en esta y otras zonas cercanas.

    Refined assessment of the geographic distribution of Geoffroy's cat (<i>Leopardus geoffroyi</i>) (Mammalia: Felidae) in the Neotropics

    Abstract Understanding the fine‐scale geographic distribution of a species has applications in biogeography, ecology, evolution and conservation. Species distribution models (SDM) have been widely used to predict geographic and climatic ranges of species. Geoffroy's cat Leopardus geoffroyi is a small felid of least concern that occupies a wide variety of habitat types in Argentina, Bolivia, Brazil, Chile, Paraguay and Uruguay. We evaluated the fine‐scale distribution of Geoffroy's cat at the sub‐continental level, estimated its current extent and area of occurrence and discussed the current and potential ranges developed with SDM. On the basis of species occurrences ( n = 1502) and large‐scale environmental data, two model types (‘environmental’ and ‘land cover’) were developed using MaxEnt. The estimated extent of occurrence of Geoffroy's cat was 3 180 664 km 2 , but the potential area of occurrence predicted by our environmental model was 70% larger due to areas with high suitability (i.e. &gt;0.5) compared to the species’ current range. The most important bioclimatic factors affecting Geoffroy's cat presence were temperature seasonality, mean temperature of the coldest quarter and annual precipitation. Two recent records obtained outside the known distribution of the species fell within the high‐suitability area (i.e. &gt;0.5) predicted by our model. Our SDM suggest that this habitat‐generalist felid is probably expanding its distribution range by taking advantage of changes in human land use.
