Composición de la comunidad de anfibios y ocupación de hábitat en la reserva “El Madrigal” de la cuidad de Loja.

Abstract

The amphibians in Ecuador are one of the most diverse groups of vertebrates, but, are threatened by anthropogenic pressures on ecosystems. Around the areas with strong threats to amphibians are the inter-Andean valleys, which houses an important diversity and endemism of this group, being important to know the state of the existing populations in the forest remnants of the region. Among them is the private reserve "El Madrigal", where the present study was developed to evaluate the amphibian community, as contribution to the knowledge of the composition and habitat use. Three transects of 1 km were used, in which visual and transect auditory survey techniques were applied. Seven species of two families were found, the most abundant being Pristimantis lymani. On the other hand, the habitat occupation patterns were evaluated, in relation to microhabitat, land use, distance to the ravine, slope and altitude. No pattern of habitat use was found, only P. Lymani, showed a distribution associated with the distance to the ravine.
