Salvin's Spiny Pocket Mouse (Liomys salvini) I
The most abundant of the terrestrial rodents (mice and rats) in Laguna de Apoyo Nature Reserve is probably Salvin's Spiny Pocket Mouse (Liomys salvini). Near houses, their principal competitor appears to be the House Mouse (Mus musculus), which is an exotic, invasive species. Liomys salvini lives in underground burrows with many entrances, and the terrain of the volcanic crater interior in Laguna de Apoyo Nature Reserve is ideal habitat for this species. We even have a family living in the yard of Estacion Biologica!
Pocket mice can be identified by the foot pads, as shown above. Pocket mice can carry food in pouches in their cheeks, allowing for rapid foraging with ingestion occuring later. We are investigating the diets, population, and distribution patterns of this species in Laguna de Apoyo Nature Reserve.
We are seeking volunteers who would like to assist in our studies of the rodents of Laguna de Apoyo Nature Reserve. Would you like to participate? Please contact us.
