Presencia de Gambusia affinis (Baird & Girard, 1853) en un humedal boscoso del Sur de Chile. Posibles implicancias sobre la fauna local de invertebrados. Presence of Gambusia affinis (Baird & Girard, 1853) in a forested wetland in Southern Chile. Possible implications on the local invertebrate fauna.

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
