Abstract (English): The objective of this research was to determine the water quality from the evaluation of the effect on the change of the soil use, based on the study of aquatic macroinvertebrate dynamics as bioindicators, in the "El Sapanal" microbasin. A description and survey of areas with different soil uses (pasture, secondary forest and agricultural crops) was carried out by direct observation, field data collection using GPS, and applying AutoCAD Map 3D. Samples of aquatic macroinvertebrates was taken with a D type net in different habitat types, and identified up to the family level, using stereoscopic microscopy. The identified macroinvertebrates were used in the modified Biological Monitoring Working Party index for Costa Rica (BMWP-Cr). The index showed that the use of forest soil has excellent water quality, unlike the use of agricultural land and pasture with regular quality water. This shows that the reduction of the riparian strip contributes to the degradation of the interior habitat and the water quality of the micro watershed. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): El objetivo de esta investigación fue determinar la calidad de agua a partir de la evaluación del efecto en el cambio del uso de suelo, basadas en el estudio de la dinámica de los macroinvertebrados acuáticos como bioindicadores, en la microcuenca "El Sapanal". Se realizó una descripción y levantamiento de áreas con distintos usos de suelo (pastizal, bosque secundario y cultivos agrícolas) mediante la observación directa, recopilación de datos de campo tomados con GPS, y aplicación del programa AutoCAD Map3D. Se tomaron muestras de macroinvertebrados acuáticos con una red tipo "D" en diferentes tipos de hábitat, para su identificación por medio de estereoscopios hasta nivel de familia. Los macroinvertebrados identificados fueron utilizados en el índice Biological Monitoring Working Party modificado para Costa Rica (BMWP-Cr). El índice mostró que el uso de suelo del bosque posee aguas de calidad excelente, a diferencia del uso de suelo agrícola y pastizal con aguas de calidad regular. Esto demuestra que la reducción de la franja ribereña contribuye a la degradación del hábitat interior y de la calidad del agua de la microcuenca. [ABSTRACT FROM AUTHOR]
