The panamanian climbing rat, mammalia, rodentia, cricetidae, Tylomys panamensis (Gray, 1873): new report in Darien

This study reports a new record for Tylomys panamensis, increasing its range by 121 km, 66o NW from the original endemic distribution. It has been considered as Data Deficient by IUCN as no information has been published for almost 64 years. Based on our long term surveillance at the Darien’s canopy, using Orion Camera System (OCS), we have been able to obtain information about their circadian and monthly activity over the course of one year. The presence of T. panamensis remarks the importance of the largest National Park of the Mesoamerican region and claim urgency to be protected from its actual devastation, particularly the montane forest in the rest of the provinces of Darien and Panama.

Basados en nuestra vigilancia de dosel en Darien a largo plazo utilizando el Sistema de Camaras Orion (SCO), hemos podido obtener informacion de su actividad circadiana y actividad mensual por espacio de un ano. La presencia de T. panamensis confirma la importancia del mayor Parque Nacional de la region Mesoamericana clamando con urgencia a ser protegido de su actual devastacion, y en particular los bosques montanosos del resto de las provincias de Darien y Panama.
