동부회색다람쥐(Sciurus carolinensis)는 북아메리카 동부가 원산지이나 유럽을 비롯한 여러 지역에 성공적으로 도입된 중형 수목성 설치류로, 몸무게는 최대 600g에 달합니다. 매 가을 수천 개의 견과류와 씨앗을 땅에 묻어 저장하며, 잊어버린 저장소에서 의도치 않게 나무를 발아시키는 역할을 합니다. 영국에서는 먹이 경쟁에서 우위를 점해 토착종인 붉은다람쥐를 대부분 대체했습니다.

Cochabamba Akodont

The Cochabamba akodont (Akodon siberiae) is a small South American rodent endemic to the Cochabamba department of Bolivia. A member of the speciose genus Akodon — the so-called grass mice — this species inhabits humid montane grasslands and shrublands in the Andes, typically at elevations between 2,500 and 3,800 metres. Like other akodont rodents, it is primarily granivorous and insectivorous, foraging among dense grass tussocks and low vegetation for seeds, invertebrates, and plant material. The species is fossorial to a degree, constructing runways and shallow burrows beneath grass cover that provide shelter from predators including raptors and small carnivores. Akodon siberiae was described relatively recently from specimens collected in the Cochabamba region and remains poorly known; much of its ecology and reproductive biology has been inferred from better-studied congeners. Population size estimates are unavailable, though the IUCN classifies it as Near Threatened due to its restricted range and ongoing habitat conversion driven by agricultural expansion, livestock grazing, and burning of Andean grasslands. The species may have some tolerance for modified habitats but its dependence on intact puna and montane scrub makes it vulnerable to continued land-use change. Conservation measures such as protection of remnant native grassland within its limited range are considered important for its long-term persistence.
