          Abstract

          Se analizó la dieta de una población del sapito de cuatro ojos (Pleurodema thaul) de la localidad de Hualpén (Talcahuano, Chile). El estudio se realiza durante los períodos reproductivos (junio-diciembre) que comprenden los años 2000 y 2001. Estos anuros destinan una menor importancia al consumo de presas durante la época reproductiva, por lo que presentan una baja frecuencia de ocurrencia (50,63%). La dieta de P. thaul está compuesta fundamentalmente de artrópodos (IRI = 0,92), con un consumo de menor importancia de vegetales (IRI = 0,035). Se determinó una alta diversidad de ítemes de presa (37 taxa). Los ítemes alimentarios dípteros y arácnidos son los más comunes. No se detectan relaciones entre el tamaño de las presas y el tamaño de los anuros

          We examined the diet for four eyes toad (Pleurodema thaul) in Hualpén (Talcahuano, Chile). The study was carried out during the breeding season (June - December) in 2000 and 2001. These anurans consume fewer preys during the breeding season, and they present a low occurrence frequency (50.63%). The results show the P. thaul diet include for arthropods (IRI = 0.92), with a lower consumption of vegetables (IRI = 0.035). We determined a high diversity of prey, with 37 taxa of invertebrates. The alimentary items dipteral and arachnids are the most common. No relationships occurred between the size of the preys and the size of the anurans
