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.

Gorila Occidental

El primate más grande del mundo, los gorilas occidentales pesan hasta 180 kg y habitan los bosques tropicales y subtropicales del África ecuatorial. Principalmente herbívoros, viven en grupos familiares liderados por un macho de espalda plateada que protege la tropa y media en los conflictos sociales. En Peligro Crítico, con poblaciones amenazadas por la deforestación, la caza furtiva para la venta de carne de monte y los brotes del virus del Ébola.
