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。

Clermont'S Spleenwort

Clermont's Spleenwort, Asplenium clermontiae, is a small fern in the family Aspleniaceae with a very restricted distribution in the Indian Ocean islands, believed to occur in the Mascarene archipelago. The genus Asplenium, the spleenworts, is one of the largest and most diverse fern genera globally, with species adapted to rock faces, tree bark, and moist forest floors across tropical, subtropical, and temperate regions. Clermont's Spleenwort, like many island-endemic Asplenium species, likely grows epiphytically on tree trunks or lithophytically on humid rock faces in montane forest, protected from the desiccating conditions of lower elevations. Island endemic ferns in the Mascarenes face severe threats from habitat loss driven by agricultural conversion, invasive plant species that alter forest structure, and introduced herbivores that destroy forest understory vegetation. Many spleenwort species have very small total populations confined to remnant forest patches. Asplenium clermontiae is considered rare and potentially threatened, though formal assessment data on its exact population size and trend are limited. Conservation of the species depends on the protection and restoration of humid forest habitats on the islands where it occurs.
