MACROINVERTEBRADOS EN LAS LAGUNAS DE PUERTO VIEJO, LIMA – PERÚ

Abstract

Se realizo un estudio para evaluar la biodiversidad y similaridad de los macroinvertebrados del bentos de las lagunas de Puerto Viejo del 15 de Julio al 15 de Octubre del 2001. Se realizaron siete muestreos (M) temporales en ocho estaciones (E) espaciales en sus lagunas naturales y artificiales. Se calculo la diversidad alfa usando el Indice de Diversidad de Shannon-Wienner (H´), el de Equidad de Pielou (J´) y el Indice de Dominancia de Simpson (C). Para la determinacion de la diversidad beta se empleo los Indices cuantitativos de Sorensen y Morisita-Horn. Un total de 5519 especimenes, tres filas, seis ordenes, nueve familias y 10 especies fueron colectadas en el macrozoobentos durante todo este estudio. Las taxas mas dominantes durante este estudio fueron: Melanoides tuberculata (Muller) (Mesogastropoda: Thiaridae) con 3276 individuos (59,36 %), Chironomus sp. (Diptera: Chironomidae) con 1281 individuos (23,21 %) y Heleobia cumingi (Orbigny) (Mesogastropoda: Hydrobiidae) con 891 individuos (16,14 %). Estas tres especies presentaron una distribucion espacial amontonada a lo largo de todos los muestreos realizados. Los valores de diversidad alfa mediante los Indices de diversidad de Shannon-Wiener, de Equidad de Pielou y de Simpson no variaron significativamente entre los siete muestreos realizados y entre las ocho estaciones censadas.
