Escarabajos coprófagos (Coleoptera: Scarabaeidae: Scarabaeinae) como indicadores de diversidad biológica en la Parroquia de Lita. Imbabura-Ecuador.

Abstract

This study was done in Lita, Imbabura, Ecuador, during the months of October, November, December 2012 and January, March, May, 2013. The activities carried out in this project aim to assess changes in the biological species and the composition of the fauna of dung beetles along a gradient of forest management in not intervened and intervened forest diversity; with differences of vegetation and tree density. The collection of species of study; (Coleoptera: Scarabaeidae: Scarabaeinae) was performed using "pit-fall" traps baited with pig excrement. 372 individuals belonging to 10 genera and 20 species were captured. Using non-parametric methods accumulation curves and richness estimates showed that estimated and observed values agreed; they adjusted to expected patterns. It was determined that there are differences in species richness and composition of the dung beetles changes in vegetation, forest cover and resources, but no significant influence of abiotic factors and environmental variables: precipitation, temperature and humidity.
