Escarabajos coprófagos (Coleoptera: Scarabaeidae: Scarabaeinae), como indicadores de diversidad biológica en el Refugio de Vida Silvestre y Marino Costera Pacoche

Abstract

This study was conducted in the refuge for marine wildlife and wildlife Pacoche which is located 25km from Manta city in Manabí province, during the months of July to December 2014, in two types of forest life: a intervened forest and a not intervened one, they differentiated by the density of its vegetation. In the field study, the catches were taken using “pit.fall” traps baited with pig faeces. The traps were installed in 20 sampling points; in each point four traps separated by one meter of each other were installed. During the 6 months of study 689 individuals of which 262 are for the BI and the remaining 427 from BNI related to 8 genera and 14 species they were captured. The species of greatest frequency index were: Onthophagus sp1; Onthophagus sp3; Canthidium sp3; Canthidium sp4. Regarding the relationship between abiotic factors with wealth and abundance in both forest types, it is shown that environmental variables did not have any association with wealth, but in general there are plenty of influence variables as temperature and humidity, particularly humidity.
