Common Aloe-moss

<em>Aloina aloides</em>, commonly known as Common Aloe Moss, is a small moss in the family Pottiaceae. This species is classified as Critically Endangered on the IUCN Red List, representing a severe conservation concern with populations recorded across several European countries including Belgium, France, Germany, the Netherlands, and the United Kingdom. Common Aloe Moss typically inhabits open, disturbed, or sparsely vegetated ground in temperate and Mediterranean forest zones, often colonizing bare calcareous soils, chalk banks, old walls, and arable field margins. It forms small cushions or turfs of erect, spoon-shaped leaves that are distinctive for their inrolled margins and papillose surface. This moss is particularly associated with traditional low-intensity agricultural landscapes where bare ground is regularly created, and its dramatic decline is closely linked to the intensification of farming practices and the loss of suitable open, calcareous habitats across Europe. Biological traits of this species remain poorly documented in the scientific literature.

Polar bear

北极熊是地球上最大的陆地食肉动物，体重可超过700千克，分布于从加拿大到俄罗斯的北极海冰区。是高度特化的海洋哺乳动物，依赖海冰捕猎环斑海豹和髯海豹。是优秀的游泳者，能够横渡广阔的开阔水域。被列为易危种，因气候变化导致北极海冰迅速减少，种群正受到严重威胁。
