Resumen
[ES] El Alto Guadalquivir es una comarca ubicada en el noreste de Andalucía, donde confluyen los espacios naturales con las zonas de cultivo. Uno de los ecosistemas más desconocidos de esta comarca son los humedales, los cuales están afectados por gran variedad de impactos antrópicos. En este trabajo, se estudia la biodiversidad de macroinvertebrados bentónicos de estos humedales con el fin de evaluar su estado ecológico. Para ello, se realizaron una serie de muestreos de tipo cualitativo-semicuantitativo entre los meses de febrero y mayo de 2015. Los resultados obtenidos se complementaron con datos de nutrientes y otras variables ambientales. Todos estos datos nos permitieron calcular un índice de calidad ambiental (ECELS), así como diferentes índices de diversidad. Se determinaron un total de 16 familias de macroinvertebrados con una alta dominancia de la familia Chironomidae. El estado de conservación de los humedales fue catalogado como “deficiente” debido al alto impacto antrópico, por lo que podría postularse una restauración de estos ecosistemas.

The results were supplemented with data from nutrients and other environmental variables. All these data allowed us to calculate an index of environmental quality (ECELS) as well as different indices of diversity. A total of 16 families of macroinvertebrates were determined with high dominance of chironomid. The conservation status of wetlands was classified as "poor" due to high human impact, so that, it could be run a restoration of these ecosystems.
