Abstract
Las especies invasoras son la principal causa de pérdida de biodiversidad del planeta, producto de la depredación que afecta a la fauna local mediante competencia, hibridación, alteración del hábitat y transmisión de enfermedades. En este estudio se describe la posible implicancia del pez mosquito sobre la fauna de invertebrados en un humedal boscoso presente en la región de la Araucanía, Chile. Los resultados nos indican la presencia de Gambusia affinis en todos los sitios de muestreo, destacándose su gran adaptabilidad a la temperatura y pH. El rol depredador de Gambusia affinis sobre mosquitos, puede favorecer al desarrollo de sus larvas, al consumir invertebrados predadores de éstas, influyendo en la estructura trófica de las comunidades.
Invasive species are a leading cause of loss of biodiversity on the planet, due to predation affecting the local fauna through competition, hybridization, habitat alteration and disease transmission. In this study is described the possible implication of mosquito fish on invertebrate fauna in a forest wetland present in the Araucania region, Chile. The results indicate the presence of Gambusia affinis in all sampling sites, highlighting its adaptability to temperature and pH. The predatory role of Gambusia affinis on mosquitoes, can favor the development of their larvae, invertebrate predators to consume them, influencing the trophic structure of communities.
