RIVERA-USME, JOHN JADER; CAMACHO-PINZON, DIANA LUCÍA and BOTERO-BOTERO, ALVARO. Numeric Structure Of The Aquatic Entomologic Fauna In Eight Streams Of The Departament Of Quindío-Colombia. Acta biol.Colomb. [online]. 2008, vol.13, n.2, pp. 133-146. ISSN 0120-548X.
A study of the aquatic entomologic fauna of eight streams from department of Quindío, Colombia in La Tebaida and Calarcá was carried out. During August to December of 2004, 1917 individuals were collected: Trichoptera with 524 specimens (Hydropsychidae with 425 was the most abundant family), Coleoptera with 421 (Elmidae with 396 individuals), Heteroptera 391, Odonata 216, followed by Ephemeroptera, Diptera and Neuroptera. The ecological indexes used were the Shannon-Wiener diversity, total richness and equity of Pielou which showed high values; the similitude of Jaccard for streams La Tebaida and Calarcá was 0,66 making evident few variations. Through an analysis of the chemical and physical variables good conservation level in this streams was determined
