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.

With the exception of the forests of the Itaya river basin, the area of influence of the Iquitos-Nauta highway and the middle basin of the Nanay and Tigre rivers, there is no information on the current status of Cheracebus sp. populations and habitat, which motivated this study. The objectives were aimed at obtaining more information on Cheracebus sp. and the state of its populations. Linear transect censuses were conducted from May to November 2019 in forests of the Itaya, Nanay and Tigre river basins. In 1659 km of covered length, 32 groups were sighted; of them, 17 corresponded to the Nanay river basin. Groups with four individuals were seen more frequently in the Nanay river basin; relative abundance and population density were slightly higher in the Itaya river basin with 0.3 groups/ 10 km and 4.2 individuals/ km2. In the study area, forests are highly disturbed from the banks of ri...

In this work, the larger mammals that inhabit the montane forests of the department of Huánuco are studied to determine the diversity of species and the status of their populations. Linear transect censuses and interviews were conducted between 2014 and 2015 on six sampling sites corresponding to five provinces. 439 records belonging to 37 species were obtained from the censuses and nocturnal explorations. Of these species, 4 are endemic to Peru and 9 are in some conservation category of Peruvian legislation. The most representative orders corresponded to carnivores and primates with 11 and 10 species, respectively, while the most frequent sightings were of Tremarctos ornatus (43 records), Nasua nasua (34 records) and Cuniculus paca (32 records). The Shannon-Wiener and Simpson Diversity Indices indicate Miraflores as the sampling site with the highest diversity (H'=3.11, 1-D=0.95). The ...

Con excepción de los bosques de la cuenca del río Itaya, área de influencia de la carretera Iquitos-Nauta y cuenca media de los ríos Nanay y Tigre, no hay información sobre el estado actual de la población y hábitat de Cheracebus sp., lo que motivó el desarrollo de este estudio cuyos objetivos estuvieron orientados a obtener más información sobre el estado actual de esta especie. Para ello, de mayo a noviembre del 2019 se realizaron censos por transecto lineal en bosques de las cuencas de los ríos Itaya, Nanay y Tigre. En 1659 km de longitud recorrida se avistaron 32 grupos de Cheracebus sp., de ellos, 17 correspondieron a la cuenca del río Nanay. Grupos con cuatro individuos se avistaron con más frecuencia en la cuenca del río Nanay; la abundancia relativa y la densidad poblacional fue ligeramente mayor en la cuenca del río Itaya con 0.3 grupos/10 km y 4.2 individuos/km2....
