Cliff Hair Grass

Cliff Hair-grass, Deschampsia cespitosa subsp. or related species within the Poaceae, is a tufted perennial grass adapted to moist, rocky cliff habitats, stream banks, and alpine or subalpine meadows in temperate mountain regions of Europe and North America. The genus Deschampsia, the hair-grasses, includes delicate, fine-leaved grasses with elegant, open panicles of tiny, often silvery or purplish spikelets that catch the light in mountain settings. Cliff-dwelling forms occupy ledges, crevices, and rocky terraces on cliff faces, benefiting from the stability provided by the cliff substrate and reduced competition from larger plants. The leaves are narrow, rough-edged, and rigid, adapted to exposed, windy conditions. Hair-grasses form dense clumps or tussocks that stabilize thin cliff soils and provide habitat for invertebrates. The species is widespread in cool, moist montane habitats across the Northern Hemisphere and is generally not considered threatened. It tolerates a wide range of soil chemistry and is among the first grasses to colonize disturbed mountain terrain. Deschampsia species play important roles in alpine ecosystem dynamics, including interactions with soil crust communities and montane invertebrate fauna.

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。
