Abstract

En un estudio realizado en el mes de mayo del 2012, utilizando una red Surber de 30 x 30 cmde área de superficie y 0,5 mm de abertura de malla, en los ríos: Pindo Mirador, Pindo Grandey Alpayacu, ubicados en el sector de Mera, provincia de Pastaza de la Amazonía ecuatoriana,se analizó la diversidad y la abundancia de los macro invertebrados bentónicos utilizando losíndices BMWP/Col y EPT. Se logró determinar que la calidad del agua de los ríos PindoMirador y Pindo Grande es buena mientras la del río Alpayacu es mala. Este estudio da unaidea general de la situación ambiental de los ecosistemas lóticos cercanos a la EstaciónBiológica Pindo Mirador. Los resultados de ésta investigación permiten determinar laimportancia de las micro-cuencas de los ríos Pindo Mirador y Pindo Grande como fuente deagua para las poblaciones que se encuentran río abajo, así como el modo en el cual lapresencia o ausencia de organismos bioindicadores (macroinvertebrados) indica la calidad delagua y de los bosques de la micro-cuenca.

Abstract:

In May 2012, using a 30x30 cm surface and 0.5 mm aperture Surber net in the rivers: PindoMirador, Pindo Grande and Alpayacu, located in Mera, Pastaza, Ecuadorian Amazonia, thediversity and abundance of macro invertebrates was analyzed applying the BMWP/Col and theEPT indexes. It was determined the good Pindo Mirador, Pindo Grande and Alpayacu rivers’water quality, as well as the bad Alpayacu river’s water quality. This work provides an overviewof the environmental situation of aquatic ecosystems near Pindo Mirador Biological Station, ithighlights the importance of the rivers’ micro-watersheds near Pindo Mirador Biological Station,used as water source by the populations living downstream, and shows how macroinvertebrates can be used as bioindicators for the water and forests quality.
