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 Mycocalia

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

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 Mycocalia

<em>Mycocalia denudata</em>, the common mycocalia, is a species of nidulariales fungus in the family Nidulariaceae, commonly known as bird's nest fungi due to the resemblance of their fruiting bodies to tiny nests containing eggs. <em>Mycocalia denudata</em> is a saprotrophic species that typically grows on decaying wood, plant debris, and humus-rich substrates in moist temperate forests. The minute cup-shaped fruiting bodies contain peridioles — small lens-shaped structures containing spores — which are dispersed by raindrops splashing into the nest, propelling them outward. Its geographic range includes Europe, with documented occurrences in Belgium, Denmark, Norway, and Sweden. The species is currently assessed as Least Concern by the IUCN, reflecting its adaptability to a range of decomposing substrates in temperate woodland and forest edge habitats. Biological traits such as lifespan, body size, and diet remain poorly documented for this species in the formal scientific literature. As a saprotroph, <em>Mycocalia denudata</em> contributes to nutrient cycling and decomposition processes in forest ecosystems, breaking down lignocellulosic material and returning organic matter to the soil.
