El Perú reporta una alta diversidad de mamíferos, sin embargo no existe al presente un departamento o región con una lista actualizada de mamíferos. Por ello, se presenta aquí una lista actualizada para Ucayali, la que incluye 192 especies, en 11 órdenes y 35 familias (38% de la mastofauna peruana). Del total de especies, 56 son registradas en Áreas Protegidas y 189 especies en Áreas No Protegidas. En Ucayali se encuentran tres especies endémicas para el país: la ardilla Sciurus pyrrhinus, el ratón cricétido Neusticomys peruviensis y el ratón equímido Makalata rhipidura. Se encontraron 86 localidades diferentes con registros de especímenes (la mayoría ubicados a lo largo de ríos). Se identificaron dos zonas con pocos o ningún registro denominadas “vacíos de información”: 1) la zona Nor Oriental de Ucayali (parte de la Reserva Nacional Sierra del Divisor),...

Camera traps are a powerful tool for inventorying elusive and rare species and very useful to obtain ecologi- cal data for plans that involve wildlife conservation. In Peru, several surveys have been carried out in lowland Amazonia especially in the southeastern part of the country, but none in montane cloud forests or Yungas. We present the first camera trap studies produced in Peruvian Yungas at the locality of Querocoto village (Chota, Cajamarca), based on 2002 (dry season) and 1264 (wet season) camera traps-days (CTD). Two localities were surveyed in wet and dry season: The Pagaibamba Protection Forest and the San Lorenzo Forest. The wet season study was carried out in October and November, and the dry season in July to September of 2008. Eight mammalian species were recorded in both seasons. Some 66 (91.7%) independent records were obtained in the dry season, but only six (8.3%) in ...

The present work documents the diversity of mammals in the headwaters of the Apurímac river, one of the most important information gaps in Peru, based on an evaluation of fi ve sampling areas in the departments of Apurímac (Cconoc, Velavelayoc), Ayacucho (Yanamonte, Ccentabamba) and Cuzco (Catarata). Capture’s effort was 1280 trap-nights and 41 mistnet-nights. Sixty species were recorded in the study area and included 15 threatened species and four species endemic to Perú. As expected, bats and rodents were the most diverse orders (66,7 %). The species diversity in the sites sampled declines signifi cantly with elevation from the lowest elevation sites (Ccentabamba and Catarata) to the highest (Velavelayoc). The marsupial Monodelphis peruviana and the Dwarf Brocket deer Mazama chunyi are fifi rst records for the department of Ayacucho. The bats Artibeus planirostris and Myotis keays...

El presente trabajo documenta la diversidad de los mamíferos de la cuenca del río Apurímac, uno de los vacíos de información más importantes del Perú, en base a una evaluación de cinco lugares de muestreo en los departamentos de Apurímac (Cconoc, Velavelayoc), Ayacucho (Yanamonte, Ccentabamba) y Cusco (Catarata). El esfuerzo de captura fue de 1280 trampas noche y 41 redes noche. Se registraron 60 especies en el área de estudio; incluyendo 15 especies bajo alguna categoría de conservación y cuatro endémicas a nivel del país. Como era de esperarse, los murciélagos y los roedores fueron los órdenes más diversos (66,7 %). La diversidad de especies en los sitios de muestreo decrece signifi cativamente con la elevación desde los puntos de muestreo más bajos (Ccentabamba y Catarata) hasta el más alto (Velavelayoc). El marsupial Monodelphis peruviana y el venado enano Mazama ...
