  Although Ecuador is among the most biologically diverse countries of the world \cite{myers2000biodiversity}, accurate data on the distribution and abundance of terrestrial mammals inhabiting the Pacific lowlands forests remains incomplete \cite{parker1992status}. The high diversity present in the area and the vast threats the species are facing, make this region an ideal location to apply standardized methods to collect information on the mammal communities and their adaptation to human modified landscapes.     The most commonly used methods to study the mammals present in an area include line transects (direct and indirect observation), the use of traps and interviews \cite{plumptre2000monitoring, silveira2003camera,agostini2015population}. Yet, most of the time these methods are hard to replicate, standardize and are likely to present some degree of bias \cite{ahumada2013monitoring}. Several factors have led to an increase in the use of camera-traps in mammal studies over the last decades. These include the opportunity to maximize encounter rate of terrestrial mammals, especially the cryptic ones, they are relatively inexpensive, efficient and easy to provide the basis for a standardized methodology \cite{carbone2001use, \cite{carbone2001use,tobler2008evaluation,  rovero2009camera, ahumada2013monitoring}
