Este recurso corresponde al proyecto orientado a evaluar la calidad ecológica de los ecosistemas fluviales en la zona altoandina de la cuenca media del río Chicamocha (Boyacá, Colombia). Las entidades gestoras del agua requieren diagnósticos precisos para implementar medidas de control y de uso eficiente de los recursos hídricos. Para ello, se emplearon métodos que integran métricas e índices biológicos que permiten una evaluación confiable del estado ecológico de los sistemas fluviales. En los tres ríos evaluados, ubicados en el municipio de Monguí y pertenecientes al Complejo Biogeográfico Siscunsí-Óceta, se recolectaron 9.137 individuos (291 registros biológicos)de macroinvertebrados acuáticos durante dos épocas del año, agosto y diciembre de 2022. La identificación taxonómica se realizó principalmente hasta el nivel de familia, aunque algunos especímenes solo pudieron determinarse hasta el nivel de clase.
Se realizaron muestreos de macroinvertebrados acuáticos con red Surber en nueve puntos de muestreo (tres por río) durante épocas seca y lluviosa. Paralelamente, se registraron parámetros hidromorfológicos, físicos y químicos, así como componentes estructurales que integran los índices evaluados.
