Resumen
Se describen los refugios de murciélagos encontrados en un área de selva amazónica de los alrededores de Iquitos (Departamento Loreto, Perú). Los muestreos en ambientes naturales se realizaron mediante caminatas diurnas y encuestas a pobladores, y en las áreas urbanas y suburbanas fueron diurnos y nocturnos, con visitas a edificios y puentes donde previamente se había registrado la presencia de especies. En refugios no modificados se registraron ejemplares apoyados sobre árboles o troncos, en huecos de árboles en pie, dentro de troncos caídos, entre hojas de palmeras, y quebradas en el suelo entre raíces de árboles. Las especies encontradas en este tipo de refugios pertenecen a las familias Emballonuridae y Phyllostomidae. En los refugios modificados se registraron especies de la familia Phyllostomidae en tiendas bífidas, tiendas tipo bote invertido y tipo cónica, y en termiteros. Los refugios artificiales fueron edificios, puentes y una embarcación, y las familias registradas fueron Emballonuridae, Noctilionidae, Phyllostomidae, Molossidae y Vespertilionidae. Especímenes de las especies de los géneros Carollia y Glossophaga se encontraron frecuentemente compartiendo refugios. También se ha observado que algunos refugios eran compartidos por ejemplares pertenecientes a diferentes niveles taxonómicos como especies, géneros, e incluso familias.
Here we describe the bat roosts found in an area of the Amazon forest around the locality of Iquitos in Loreto Departament, Peru. Natural habitats were surveyed during the day by walking, and with the help of censuses made to local dwellers; in urban and suburban areas the bats were detected by checking in buildings and bridges where the specimens were previously observed. At natural roosts, not modified by bats, the specimens were observed resting on trees or logs, inside treeholes, fallen trunks, among palm leaves, streams on the floor among roots. The species found in these shelters belonged to the families Emballonuridae and Phyllostomidae. In roosts modified by bats we recorded species of the family Phyllostomidae living on bifid tents, inverted boat tents, and conical tents, as well as in termite mounds. The artificial shelters detected were mostly buildings, some bridges and a vessel, where we have found members of the families Emballonuridae, Noctilionidae, Phyllostomidae, Molossidae and Vespertilionidae. At some localities the roosts were shared by specimens of different species, genera and even families; species that often share shelters are members of genera Carollia and Glossophaga.
