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 Rim Lichen

<em>Lecanora pulicaris</em>, the common rim lichen, is a crustose lichen in the family Lecanoraceae, order Lecanorales, within the kingdom Fungi (as the mycobiont component). It is distributed across temperate and boreal zones, with documented records from Denmark, Norway, Portugal, Sweden, and the United States. The species is assessed as Least Concern on the IUCN Red List, reflecting its widespread occurrence on bark of deciduous and coniferous trees across the Northern Hemisphere. Rim lichens in the genus Lecanora are characterized by their apothecia — disc-shaped reproductive structures rimmed by a thallus margin — which give the genus its common name. <em>Lecanora pulicaris</em> typically forms pale gray-green crustose patches on smooth to moderately rough bark surfaces, particularly favoring the bark of birch, alder, and other hardwood trees in well-lit forest and woodland environments. As a lichen, it is a symbiotic organism comprising a fungal partner (mycobiont) and photosynthetic algal or cyanobacterial partners (photobionts), deriving nutrients through photosynthesis and mineral absorption from the substrate. Biological traits such as lifespan and growth rates remain poorly documented for this taxon, though crustose lichens typically grow very slowly. It serves as a bioindicator of air quality in temperate forests.
