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 Liverwort

<em>Marchantia polymorpha</em>, the common liverwort, is a thalloid bryophyte in the family Marchantiaceae and one of the most cosmopolitan non-vascular plants on Earth. It is found across Asia, Europe, North America, and South America, typically colonizing moist, shaded habitats such as stream banks, damp soil, rock surfaces, and disturbed ground. The common liverwort reproduces both sexually, producing umbrella-shaped reproductive structures called gametangiophores, and asexually through small disc-shaped gemmae produced in cup-shaped gemma cups on the thallus surface. Its flat, ribbon-like thallus with a distinct midrib is a recognizable feature of this species. The species has not been formally evaluated by the IUCN due to its wide distribution and abundance. Marchantia polymorpha is a model organism in plant biology, widely used in laboratory research to understand plant evolution, development, and genetics. It is one of the earliest diverging lineages of land plants, providing valuable insights into the evolutionary transition from aquatic to terrestrial environments.
