Habitat & Geographic Range

白头海雕

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.

白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

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.
