Ardilla Gris Oriental

ヒガシハイリス（Sciurus carolinensis）は北米東部原産の中型樹上性げっ歯類で、ヨーロッパをはじめ世界各地に移入された外来種である。IUCNレッドリストでは軽度懸念（LC）に分類されており、都市公園や郊外の森林環境への適応力が高く、堅果の埋蔵行動が植物の種子散布に重要な役割を果たしている。英国ではニホンリスを食物競争で駆逐しており、侵略的外来種としても問題視されている。

Colombian Soft-furred Spiny-rat

<em>Diplomys caniceps</em>, the Colombian soft-furred spiny rat, is a rodent in the family Echimyidae found in Colombia. The genus <em>Diplomys</em> is characterised by a pelage that, despite the common name, is relatively soft compared to other spiny rats, with spine-like guard hairs interspersed among the fur. This species is assessed as Data Deficient by the IUCN, indicating that available information is insufficient to determine its conservation status reliably. Data Deficient assessments typically arise when a species occupies remote or poorly surveyed habitats, or when taxonomic uncertainties complicate population estimates. <em>Diplomys caniceps</em> is believed to inhabit tropical lowland and montane forests of Colombia, where it likely feeds on plant material including seeds, fruits, and fibrous vegetation. As a medium-sized terrestrial rodent, it probably serves as prey for a range of forest predators. The lack of ecological and distributional data underscores the need for targeted field surveys. Biological traits of this species remain poorly documented in the scientific literature.
