Common Orange Lichen

<em>Xanthoria parietina</em> is a foliose lichen in the family Teloschistaceae, one of the most conspicuous and widely recognized lichens across Europe and North America. It is recorded in Denmark, Norway, Portugal, Sweden, and the United States. The species typically colonizes bark, rock surfaces, walls, roof tiles, and other exposed substrates in nutrient-enriched environments. Its vivid orange to yellow-orange thallus is produced by the pigment parietin, which functions as a photoprotective compound shielding the lichen from UV radiation. <em>Xanthoria parietina</em> is considered a nitrophilous species, thriving in habitats enriched by nitrogen compounds, such as those near bird roosting sites, agricultural areas, and urban zones. It is highly tolerant of air pollution and is frequently used as a bioindicator in ecological studies. The IUCN lists this species as Least Concern given its broad distribution and tolerance of disturbed environments. As a lichen, it is a mutualistic association between a fungal partner and algal or cyanobacterial photobionts. Biological traits such as growth rates, lifespan, and dietary ecology remain poorly documented in standardized databases for lichen species.

コウテイペンギン

世界最大のペンギンであるコウテイペンギン（Aptenodytes forsteri）は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
