Habitat & Geographic Range

Cochabamba Akodont

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

ブンチョウ

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 6 distinct biome types spanning the Afrotropic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Tanzania), Asia (Taiwan, Thailand, Vietnam), Europe (5 countries), North America (United States), Oceania and the Pacific (Australia), and South America (Colombia, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

東アジアで最も人気のある飼い鳥の一つであるジャワスズメは、灰色の羽毛、鮮やかな黒い頭部、特徴的な白い頬斑、明るい赤いくちばしを持つ印象的なフィンチである。インドネシアのジャワ島とバリ島が原産地で、アジア・アフリカ・アメリカの多くの地域に導入されている。開けた草地、水田、農地に生息し、稲作に被害を与えることがある。籠鳥取引のための深刻な捕獲圧力により、原産地では絶滅危惧種に指定されている。
