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 Pear

Habitat

Found across multiple habitat types including deserts and xeric shrublands, tropical and subtropical moist broadleaf forests, and montane grasslands and shrublands, among 5 distinct biome types spanning the Afrotropic and Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Libya, South Africa), Asia (Yemen), Europe (25 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (4 countries).

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 Pear

<em>Pyrus communis</em> is a deciduous tree in the family Rosaceae, cultivated for millennia as a fruit crop and distributed across an exceptionally broad range including Libya, South Africa, Yemen, twenty-five European nations, Canada, Mexico, the United States, Australia, and four South American countries. Wild or semi-wild populations occur in deserts, xeric shrublands, tropical and subtropical moist broadleaf forests, and montane grasslands across its range. The species typically grows as a medium to large tree bearing white spring blossoms and producing the familiar pear fruit, which varies widely in shape, color, and flavor across cultivated varieties. Its taxonomy intersects with wild relatives and hybrid forms across the Palearctic, making species boundaries complex. The IUCN classifies this species as Data Deficient, reflecting uncertainty about the conservation status of wild versus cultivated populations and the difficulty of delimiting the true wild genotype from extensively hybridized agricultural forms. Biological traits including average lifespan, body measurements, and dietary ecology remain poorly documented in standardized ecological databases for this cultivated species. <em>Pyrus communis</em> has been cultivated since antiquity and remains one of the most economically significant temperate fruits globally.
