Habitat & Geographic Range

Cloud Forest Akodont

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

ハッカチョウ

Habitat

Inhabits tropical and subtropical dry broadleaf forests and tropical and subtropical grasslands and savannas within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Japan, Singapore, United Arab Emirates), Europe (7 countries), and South America (Argentina, Bolivia).

Cloud Forest Akodont

Cloud forest akodonts are small rodents in the genus Akodon (family Cricetidae, subfamily Sigmodontinae) adapted to the cool, moist cloud forests of the Andean mountain chain in South America. These small mice, typically 15–25 g body weight, are among the most diverse rodent genera in the Neotropics, with dozens of species occupying a range of habitats from tropical lowland forest to high-elevation grasslands and cloud forest margins. Cloud forest species live in mossy, fern-rich undergrowth at elevations typically between 1,500 and 3,500 meters, where they forage for seeds, fungi, invertebrates, and plant material among dense vegetation and under fallen logs. Akodonts are important prey species for forest raptors, small cats, and mustelids, and serve as seed dispersers in cloud forest ecosystems. Many cloud forest akodont species have restricted ranges tied to specific elevation bands on individual mountain ranges, making them vulnerable to climate change-driven upslope habitat shifts that compress available habitat and may eventually eliminate suitable conditions on mountains of insufficient height.

ハッカチョウ

カンムリハッカ（Acridotheres cristatellus）はIUCNレッドリストで軽度懸念（LC）に分類される。分布域全体で広く豊富に生息し、個体数は安定しており、即座の保全上の懸念はない。
