En este trabajo se presenta una lista actualizada de los anfibios distribuidos en el departamento de Loreto, Perú, incluyendo información sobre el estado de conservación a nivel internacional y nacional, el endemismo y zonas con vacíos de información. Se utilizó literatura herpetológica, bases de datos y especímenes de la colección del Departamento de Herpetología del Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos para la elaboración de esta lista. Se registraron un total de 232 especies, con los anuros (sapos y ranas) representando el 96% del total de anfibios en Loreto. Dieciocho especies son endémicas de Loreto mientras que la gran mayoría (208 especies) tienen una distribución altitudinal por debajo de los 500 m. Diez especies están en categorías de amenaza y cuatro son consideradas casi amenazadas según criterios internacionales, mientras q...

En este trabajo se presenta una lista actualizada de los reptiles distribuidos en el departamento de Loreto, Perú, incluyendo información sobre el estado de conservación a nivel internacional y nacional, endemismo y zonas con vacíos de información. Para la elaboración de esta lista se utilizó literatura herpetológica, bases de datos y especímenes de la colección del Departamento de Herpetología del Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos. Se registraron un total de 182 especies de reptiles, con los escamosos (lagartijas y serpientes) representando el 90% del total. La serpiente Helicops yacu es la única especie endémica de Loreto y la culebra Dipsas peruana es la única especie con una distribución altitudinal por encima de los 500 m. Seis especies están en la categoría de Vulnerables según la IUCN; mientras que seis están consideradas c...

This paper presents an updated list of the amphibians occurring in the department of Loreto, Peru, including information on conservation status, endemic species and areas with information gaps. Herpetological literature, databases and the collection of the Department of Herpetology of the Natural History Museum of the National University of San Marcos were used to update the species list. A total of 232 species were recorded, with anurans (toads and frogs) representing 96% of amphibians in Loreto. eighteen species are endemic to Loreto while the vast majority (208 species) have an altitudinal distribution below 500 m. Ten species are in threatened categories and four are near threatened according to international criteria; while four are considered as threatened and six as near threatened according the national list. Mayor information gaps are observed in areas near the borders with Braz...

This paper presents an updated list of the reptiles occurring in the Department of Loreto, Perú including information on conservation status, endemic species and areas with information gaps. Herpetological literature, databases and the collection of the Department of Herpetology of the Natural History Museum of the National University of San Marcos were used to update the species list. A total of 182 species were recorded, with squamates (lizards and snakes) representing 90% of reptiles in Loreto. Only one species, Helicops yacu, is endemic to Loreto and Dipsas peruana is the only species with an altitudinal distribution above 500 m. Six species are in IUCN threatened categories. Six and four species are in threatened and near threatened national categories respectively. Mayor information gaps are observed in areas near the borders with Brazil and Colombia.

This study assessed the diet of the Neotropical lizard Liolaemus polystictus from Huancavelica region in the Peruvian central Andes. The diet composition was identified from 54 sample stomach contents. Percentage of vegetable content was higher than the animal one (V% animal content= 22.97 and V% vegetable content= 77.03), and arthropods were the highest animal content with ten foods items. Within the animal content, Coleoptera were the most representative (N%= 32.05, FO= 59.26 and V%= 41.36%). No animal category showed high IRI values to be considered fundamental. There were not significant differences on prey selection between males, females and juveniles, and on vegetal volumetric contents between adults and juveniles. However, vegetal volumetric contents were significantly different between males and females. Significant differences were found between prey length, width and volume an...
