Insectos acuáticos asociados a arroyos de la Serranía de La Macuira - La Guajira, Colombia

Abstract: Los insectos acuáticos tienen gran importancia en los ecosistemas fluviales, debido a su alta abundancia y diversidad e indicadores de calidad de agua. En este trabajo, se caracterizaron las comunidades de insectos acuáticos en La Macuira, norte de La Guajira colombiana. Se seleccionaron cinco arroyos intermitentes, como sitios de muestreo: Mekijanoü, Chaamaalüü, Kanewerü, Mmalaüü y Kajashiwoü. Para la colecta de los organismos, se empleó una red Surber, durante cinco minutos. Además, se tomaron muestras de ho… Show more

“…These results differ from what was recorded by Rosado et al (2017) where Simpson's dominance index was higher in Although the order Coleoptera is relatively abundant in streams with forest cover (Meza et al, 2012), it is also detected in areas influenced by native forest. Pérez-Rodríguez et al (2021) reported this order as the most abundant in a study of five streams in the protected area of native species in the Serranía de la Macuira, Colombia; similarly, Urdanigo et al (2019) reported that this order was the most abundant in the stream with secondary native forest. The order Hemiptera was the most abundant in the stream with agricultural cover with 32 %; however, in coffee crop cover in Colombia, abundance levels of 2.6 % of the order Hemiptera were observed due to the low prevalence of the species Pontoscolex corethrurus (Annelida: Oligochaeta), which prevents further growth of the taxonomic group (Rojas-Múnera et al, 2021).…”
