Respuesta de la comunidad de anfibios a la calidad de agua de pozas temporales en el bosque seco de la Reserva Ecológica Arenillas

Abstract

Abstract:The Tumbesian region, considered one of the most important hotspot for its endemism, suffers major threats from anthropogenic activities. This region located in southern Ecuador and northwestern Peru is characterized by a marked climatic seasonality. It has an interesting diversity of amphibians, which are generally related to humid environments. The precipitation in this ecosystem is very low and added to the lack of humidity, it constitutes a limiting factor for amphibians and their tadpoles, due to the poor breeding pools, high temperatures and variations in water quality. In the present study the composition of amphibians in temporary pools and their response to water quality in the Arenillas Ecological Reserve was evaluated. The sampling was carried out in March and May of 2019 through Surveys by Visual Encounters. To evaluate the water quality, a Multiparameter equipment was used. 358 individuals of 8 species were registered. It was determined that the water quality of the seasonal pools does not influence the composition of amphibians, but that the differences observed are related to other variables.
