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.

Epaulard

イルカ科で最大の種であるシャチ（Orcinus orca）は体長最大9メートル、体重6トンに達し、北極から南極まですべての海洋に生息しています。独特の方言、狩猟戦略、集団間で異なる文化的伝統を持つ母系ポッドで生活する頂点捕食者です。一部の集団は魚類を、他の集団は海洋哺乳類を専門に捕食します。天敵はなく、シャチは生息するすべての海洋食物連鎖の頂点に位置します。
