Colombian spiny rat

<em>Proechimys canicollis</em>, the Colombian spiny rat, is a terrestrial rodent belonging to the diverse family Echimyidae, occurring in Colombia and Venezuela. Spiny rats of the genus <em>Proechimys</em> are among the most species-rich genera of Neotropical rodents, typically inhabiting lowland tropical and subtropical forests, forest edges, and secondary vegetation. The coarse, spine-like hairs that give this group its common name are thought to function as a deterrent against predators. <em>Proechimys canicollis</em> is assessed as Least Concern by the IUCN, suggesting stable populations across its range. This species likely feeds on seeds, fallen fruits, fungi, and invertebrates, and may play an important role as a seed predator and disperser in forest ecosystems. Research indicates that <em>Proechimys</em> species often achieve high local densities in undisturbed forest, making them important prey items for raptors, felids, and large snakes. Habitat loss in northern South America remains a background concern for long-term population stability. Biological traits of this species remain poorly documented in the scientific literature.

Usnea cornuta는 Parmeliaceae과에 속하는 수지형 지의류로, 준위협(NT)으로 평가됩니다. 나뭇가지와 잔가지에 매달리는 덤불 모양의 엽상체를 형성하며, 주로 습한 산림 환경에서 서식합니다. 모든 Usnea 속 종과 마찬가지로 대기 오염, 특히 이산화황에 매우 민감하여 대기 질의 유용한 생물 지표종으로 활용됩니다.
