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.

帝企鹅

帝企鹅是世界上体型最大的企鹅，身高可达1.2米，体重达45千克，栖息于南极大陆极端恶劣的环境中。它们在隆冬的黑暗中、零下60°C以下的严寒里繁殖，雄鸟将唯一的蛋置于脚背上，藏于育卵囊下孵化长达65天，而雌鸟则在此期间出海觅食。数千只帝企鹅组成的群体通过循环交换位置、使个体轮流经过温暖的核心区域这一抱团取暖行为，堪称合作生存的典范。
