Estudio de los escarabajos coprófagos (Coleóptera: Scarabaeidae: Scarabaeinae) como indicadores de la diversidad biológica en el bosque muy húmedo premontano del cantón San Miguel de los Bancos, provincia de Pichincha

Abstract

Abstract: In the canton San Miguel de los Bancos province of Pichincha Ecuador, through pitfall traps baited with pig manure, wealth, abundance and diversity of dung beetles in Undisturbed Forest (UDF) and Disturbed Forest was studied (DF). In the 1772 sampling individuals corresponding to 10 genera and 21 species were captured. The most abundant species samplings was Dichotomius sp2, and were less abundant Eurysternus sp2, and Dichotomius reclinatus, which were unique species (DF). According nonparametric estimation of wealth indices inventory of species was adequate. The greatest wealth, 21 species was obtained in the DF and the greater abundance 925 individuals was obtained in UDF. According to Simpson&#39;s index of diversity in the DF 0866 is similar to the UDF 0.875. No significant differences in abundance and richness were recorded between the two forest types (p> 0.05). In relation to abiotic factors significant relationship between species abundance and precipitation was found (p<0.001)
