Chlorine Dust Lichen

The Chlorine Dust Lichen (Chrysothrix chlorina) is a crustose lichen in the family Chrysotrichaceae, historically known from calcareous and siliceous rock surfaces and bark in parts of Europe, including the United Kingdom. It belongs to the genus Chrysothrix, a group of powdery, granular lichens that form bright yellow to greenish-yellow leprose thalli — lacking the organised cortex layers of most lichens — composed largely of granular soredia. Chrysothrix species produce unique secondary metabolites including rhizocarpic acid, which contributes to their intense yellow colouration and may serve as protection against grazing invertebrates. The Chlorine Dust Lichen takes its name from the sharp, bleach-like or chlorine odour emitted when the thallus is moistened — a distinctive diagnostic feature. The IUCN has assessed this species as Extinct in Great Britain, where it was historically recorded from ancient woodland and shaded rock sites but has not been confirmed in recent decades. Its apparent extinction in parts of its former range is attributed primarily to severe air quality degradation during the industrial era, as many crustose lichens are highly sensitive to sulphur dioxide and other atmospheric pollutants. It may persist in small areas of cleaner air, and improved air quality since deindustrialisation offers some hope for natural recolonisation.

giraffe

지구상에서 가장 키가 큰 동물인 기린(Giraffa camelopardalis)은 키가 5.5m에 달하고 체중이 최대 1,750kg에 이를 수 있다. 모든 포유류와 같이 7개의 경추로 이루어진 긴 목은 아프리카 사바나와 산림의 아카시아 나무 먹이 섭취를 위해 진화했다. 영구적인 결속 없이 느슨한 무리를 이루며 생활하는 사회적 동물로, 초저주파음과 몸짓으로 소통한다. 서식지 상실과 밀렵으로 개체군이 감소하고 있는 취약 종이다.
