In addition, we calculated BMWP/Col [10], Average Score Per Taxon (ASPT) [22], and EPT (richness and percentage of Ephemeroptera + Plecoptera + Trichoptera) indices, also widely used in South America to assess the rivers quality.

Other studies have documented either higher diversity just below a dam than at sites further downstream or decreases only in certain taxonomic groups like Ephemeroptera, Plecoptera, Trichoptera (EPT), with little difference in total diversity between upstream and downstream sites (Lessard, Hayes 3003).
punctulatus (Valenciennes) estuvo constituida en total por 13 items alimenticios, 12 items correspondientes a macroinvertebrados bentonicos: Baetidae, Leptohyphidae, Simuliidae, Chironomidae, Diptera indeterminados (1), Corydalidae, Elmidae, Coleoptera indeterminados (2), Hydropsychidae, Hydroptilidae, Hydrobiosidae, Trichoptera indeterminados (3) y un vertebrado: Rhinella limensis (Werner).
Macroinvertebrates, identified to genus, were used to determine: alpha diversity (taxa richness), species evenness (Simpson's Index), percent sensitive taxa (% Ephemeroptera, Trichoptera, Plecoptera (EPT)) and community composition (Jaccards Similarity Coefficient).
The species feeds on insect larvae, especially Diptera and Trichoptera, and is the only upper Zambezi mormyrid that feeds extensively on zooplankton.
2002) were calculated by taking into account the number of sensitive taxa (number of Ephemeroptera, Odonata and Trichoptera taxa).
El analisis de contenido estomacal del ejemplar estudiado revelo el consumo de macroinvertebrados acuaticos de los ordenes Trichoptera y Ephemeroptera en sus estadios adultos e inmaduros (larvas y ninfas); esto coincide con lo reportado en otras localidades de la Cordillera de la Costa Central (Voss, 1988).
Insecta were well represented, accounting for 49% of prey items including 8 orders: Coleoptera, Diptera, Ephemeroptera, Hemiptera (including "Homoptera"), Hymenoptera, Lepidoptera, Plecoptera, and Trichoptera. Among these, Diptera were most common, accounting for 29% of prey, which was mostly Mycetophilidae but also included Tipulidae, Chironomidae, Ptychopteridae, and Dixidae, among others that occurred more rarely and were not identified to family level.
