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).

Cochran's False Brook Salamander

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Range

Found in Mexico. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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。

Cochran's False Brook Salamander

Cochran's false brook salamander (Pseudoeurycea cochranae) is a small, slender plethodontid salamander endemic to the pine-oak and cloud forests of the eastern Sierra Madre Occidental and adjacent ranges of Mexico. Like all members of the family Plethodontidae, it is lungless — respiration occurs entirely through moist skin and mucous membranes of the mouth, constraining the species to damp microhabitats such as mossy rock faces, rotting logs, and the leaf litter layer in humid montane forest. The species is direct-developing, laying small clutches of eggs in moist terrestrial sites from which miniature fully formed salamanders emerge, bypassing the aquatic larval stage characteristic of most other amphibian orders. Pseudoeurycea cochranae is a nocturnal forager, preying on small invertebrates including collembolans, mites, and small beetles encountered during nightly activity in its humid forest microhabitat. The species is classified as Vulnerable by the IUCN owing to its limited distribution, continuing deforestation driven by logging, agricultural conversion, and human settlement in its montane range, and susceptibility to climate-driven shifts in the moisture regime of cloud forest habitats. The genus Pseudoeurycea is largely endemic to Mexico and comprises several dozen species, many of which are similarly threatened. Like several congeners, P. cochranae is named in honour of Doris Mable Cochran. Population monitoring in its restricted range is an ongoing conservation priority.
