Colombian Rhipidomys

Rhipidomys caucensis, commonly known as the Colombian Rhipidomys, is a small arboreal rodent species belonging to the genus Rhipidomys within the family Cricetidae. This species is classified as Data Deficient, reflecting a lack of sufficient information to accurately evaluate its conservation status, and indicating the need for further field investigation. It has been documented in Colombia, where it inhabits diverse terrestrial and aquatic-adjacent environments. Members of the genus Rhipidomys are typically arboreal, living in forest canopies and understories across the Andes and adjacent lowland regions of South America. These rodents are generally nocturnal and feed on a variety of plant materials including fruits, seeds, and other vegetative matter, though specific dietary records for Rhipidomys caucensis have not been documented. Biological traits of this species remain poorly documented in the scientific literature. The Data Deficient status underscores the importance of increased survey effort in Colombian forest ecosystems to better understand the distribution and ecological requirements of this arboreal rodent.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
