This report contains information about sleeping dens, population structure and the impact of hunting of the paca (Cuniculus paca Linnaeus, 1766). It is based in sleeping den observations, transect censuses and hunt- ing records. We found that each sleeping den has one to three orifices for regular access and way out, one to four orifices for circumstantial escape, and an internal cavity for the diurnal sleep. Of the total sleeping dens inspected, 67% where located between 0 and 60 m from water bodies, but some were also found as far as 100 m away. Of the population extracted by hunters, 74% were adults and only 4% were infants. The annual hunting pressure was estimated at 0,4 individuals/ km2 and the population density for the overall area at 6,2 individuals/ km2. Finally, the harvest model suggests that hunting of the paca is sustainable in Alto Itaya river basin.

Este reporte contiene información acerca de los ambientes de dormir, estructura poblacional y el impacto de la caza del majas (Cuniculus paca Linnaeus, 1766). Está basado en observaciones de madrigueras, censos por transectos y registros de caza. Encontramos que cada ambiente de dormir tenía de uno a tres orificios para el acceso y salida, uno a cuatro orificios para la fuga circunstancial y una cavidad interna para el “sueño diurno”. Del total de ambientes examinados, 67% estaban localizados entre 0 y 60 m respecto a los cuerpos de agua, pero algunos también fueron encontrados más allá de los 100 m. De la población extraída por los cazadores, 74% fueron adultos y solamente 4% correspondieron a los infantes. La presión de caza anual fue estimada en 0,4 individuos/km2 y la densidad para el área en general en 6,2 individuos/km2. Finalmente, el modelo de cosecha indica que la...

This report deals with paca sleeping dens (Cuniculus paca Linnaeus, 1766). The study was conducted between August 2006 and April 2007 and is based on detailed observations. Results indicate that this rodent uses holes in the ground or in fallen trees as sleeping dens. Each of these sleeping dens had two or more orifices and an internal cavity for the "diurnal sleep”. Typically, one orifice was for common use and the rest for the circumstantial escape. According to their form, their localization in the ground, and the number and location of orifices, sleeping dens were classified into four types, of which type A was the most common. The results also indicate a greater concentration of sleeping dens in temporary flooded gallery forest.
