American Bald Eagle

흰머리독수리(Haliaeetus leucocephalus)는 미국의 국조이자 미국 자연 보전 성공의 상징으로, 날개 폭이 최대 2.4미터에 달하며 북미 전역의 수변 삼림과 습지에 서식한다. 주로 물고기를 포식하는 강력한 공중 포식자이자 청소 동물로, DDT 오염과 남획으로 1960년대에 멸종 위기에 처했으나 농약 사용 금지와 멸종위기종보호법 시행 이후 극적으로 개체수가 회복되었다.

Common Script Lichen

<em>Graphis scripta</em>, the common script lichen, is a crustose lichen in the family Graphidaceae, order Graphidales, with a cosmopolitan distribution spanning Asia, Europe, North America, and South America. This species grows as a flat, tightly attached crust on the smooth bark of deciduous trees in humid, shaded woodland habitats, where it is often among the most frequently encountered bark lichens. The distinctive feature of <em>Graphis scripta</em> is its elongated, script-like apothecia — black, slit-like fruiting bodies that resemble ancient writing and give the species its common name. As a lichen, it represents a stable mutualistic association between a fungal partner (mycobiont) and photosynthetic algal or cyanobacterial partners (photobionts). The species is listed as Least Concern by the IUCN, reflecting its wide distribution and tolerance across a range of forested habitats. It is considered sensitive to air pollution, particularly sulfur dioxide, making it a useful bioindicator of air quality. Biological traits for this species remain poorly documented in the scientific literature, including data on growth rates, lifespan, and detailed ecological interactions beyond its known substrate preferences.
