Habitat & Geographic Range

ハクトウワシ

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Common Cave-cricket

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

Common Cave-cricket

<em>Troglophilus cavicola</em>, commonly known as the common cave cricket, is an insect species adapted to subterranean and cave environments. It typically inhabits terrestrial and freshwater ecosystems, often associated with caves, rock crevices, and other sheltered underground habitats where stable humidity and temperature conditions persist year-round. The species is classified as Least Concern on the IUCN Red List, indicating that it is not currently facing significant conservation pressure globally. Common cave cricket belongs to the genus <em>Troglophilus</em> within the family Rhaphidophoridae. As a troglophile, it is capable of completing its life cycle both inside and outside cave environments, typically foraging at night for organic matter and small invertebrates. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. Detailed geographic range and country-level distribution data are not currently available for this species, though it is associated with cave systems in European regions where suitable underground habitats exist.
