Efectos de la actividad humana sobre la diversidad de escarabajos coprófagos (Coleoptera: Scarabaeidae: Scarabaeinae), como indicadores de diversidad biológica en el Parque Nacional Cajas, sector Llaviucu.

Abstract

The following research was performed in Cajas National Park, in the area of Llaviucu; two kinds of forests were selected in order to obtain results: Pristine forest and secondary forest. The research was performed monthly, since October 2104 until March 2015 using pit-fall traps in 20 points previously selected for each kind of forest. 360 beetles were captured, they belong to two families: Scarabaeidae and Carabaeidae, 6 genders and 6 species. 168 beetles were found in secondary forest from which 99 were coprofago, 93 of them are part of Uroxys sp1. 192 beetles were captured in the pristine forest, 74 of them belong to coprofago beetles, and the most representative specie is Uroxys sp1. Using statistical analysis we found that the type of forest has a high importance for Uroxys sp1, Copris sp1 y Carabidae sp1. Finally, the environmental factors considered to determinate the abundance of the community of beetles were: temperature, humidity and rainfall.
