| dc.description | The studies related to dietary composition of anurans present in Chile are a field sparsely explored and allow to contribute with knowledge about the biology of the species. Alsodes coppingeri inhabits mountain streams in Nothofagus temperate forests, of Chilean Patagonia. These frogs have been found under logs in stream margins. In this study, 44 specimens of A. coppingeri from Laguna Caiquenes, Tortel and Villa O’Higgins (Aysen Region, Chile) were analyzed. The prey items were ranked at the ordinal level. The frequency of occurrence percentage and abundance of prey items and relative importance index (IRI) were estimated. The frequency of occurrence percentage was 70.5%, where the diet of A. coppingeri was mainly composed of arthropods. The most important preys were beetles, springtails, flies, spiders and isopods, with an obvious predominance of larval stages of beetles, flies and moths. | en-US |
| dc.description | Los estudios relacionados con la composición dietaria de los anuros presentes en Chile son un campo escasamente explorado y que permiten aportar con conocimiento sobre la biología de las especies. Alsodes coppingeri habita los arroyos de montaña de los bosques templados de Nothofagus de la Patagonia chilena. Estos anuros han sido encontrados bajo troncos en los márgenes de arroyos. Para este estudio se analizaron 44 especímenes de A. coppingeri provenientes de Laguna Caiquenes, Caleta Tortel y Villa O’Higgins (Región de Aysén, Chile). Los ítems presa fueron clasificados a nivel ordinal y se estimó la frecuencia de ocurrencia, de abundancia e índice de importancia relativa (IRI). Se determinó un 70,5% de frecuencia de ocurrencia, donde la dieta de A. coppingeri estuvo compuesta principalmente de artrópodos. Las presas más frecuentes correspondieron a coleópteros, colémbolos, dípteros, arañas e isópodos, con un notorio predominio de estados larvales de coleópteros, dípteros y lepidópteros. | es-ES |
