Central Andes Oldfield Mouse

The Central Andes Oldfield Mouse (Thomasomys contradictus) is a species in the genus Thomasomys. It is currently classified as Data Deficient on the IUCN Red List. Found in Colombia.

Common Bunomys

The common bunomys (<em>Bunomys chrysocomus</em>) is a small rodent species found in diverse terrestrial and aquatic habitats, including tropical forests and adjacent ecosystems. This species is classified as Least Concern on the IUCN Red List, reflecting a currently stable population without immediate conservation concerns. As a member of the family Muridae, the common bunomys is an endemic rodent of Sulawesi, Indonesia, where it typically inhabits montane forest environments at moderate to high elevations. The species often forages on the forest floor, feeding on seeds, fruits, fungi, and invertebrates. Its diet and foraging behavior make it an important contributor to seed dispersal and nutrient cycling in its native forest ecosystems. The common bunomys is typically nocturnal and solitary in its habits, as is characteristic of many rodents in its genus. Biological traits of this species remain poorly documented in the scientific literature.
