Colombian Speckled Tree-rat

<em>Pattonomys semivillosus</em>, the Colombian speckled tree-rat, is an arboreal rodent in the family Echimyidae distributed within Colombia. Members of the genus <em>Pattonomys</em> are associated with tropical forest canopy habitats, where their semi-arboreal lifestyle allows exploitation of fruiting trees and epiphytic vegetation. The speckled pelage characteristic of this species likely provides camouflage within dappled forest light. <em>Pattonomys semivillosus</em> is currently listed as Least Concern by the IUCN, reflecting a population not considered to be under immediate threat of significant decline. However, like many forest-dependent Neotropical rodents, this species may be sensitive to deforestation and habitat fragmentation, which reduce connectivity between forest patches and limit access to food resources and mates. The species is presumed to feed primarily on plant matter, including seeds, fruits, and bark. Its ecological role likely includes seed dispersal within its forest habitat. Biological traits of this species remain poorly documented in the scientific literature.

Common Ringlet

Common Ringlet (Coenonympha tullia) is classified as Extinct (EX) on the IUCN Red List. This species has been declared extinct, with no known living individuals remaining in the wild or in captivity.
