Colt's-foot Groundling

<em>Scrobipalpula tussilaginis</em>, the colts-foot groundling, is a gelechiid moth in the family Gelechiidae recorded from Belgium, Denmark, and Sweden, with occurrence in terrestrial and freshwater habitats. This species has not been evaluated by the IUCN. The common name indicates a larval association with coltsfoot (<em>Tussilago farfara</em>), a widespread ruderal Asteraceae of disturbed habitats, roadsides, and stream banks across temperate Europe. Gelechiid moths are a highly diverse family with the majority of species being leaf miners, stem borers, or seed feeders in their larval stage, making them important but often overlooked components of herbivore communities in temperate grasslands and disturbed habitats. <em>Scrobipalpula tussilaginis</em> adults are small, cryptically patterned moths, as is typical of the family Gelechiidae. Their small size and nocturnal habits make them difficult to survey without targeted light trapping or larval host-plant searches. The species likely completes a single generation per year in its northern European range. 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。
