Habitat & Geographic Range
coastal primrose
Typically found in diverse terrestrial habitats from tropical forests to temperate regions.
Distributed across Canada, Finland, Iceland, Norway, and Sweden.
Polar bear
Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
coastal primrose
Coastal primrose (Primula stricta) is a small perennial herb in the family Primulaceae, distributed across Arctic and subarctic coastal habitats in Canada, Greenland, Iceland, Norway, Svalbard, and northern Russia. It grows on rocky shores, coastal meadows, salt marshes, and gravelly riverbanks at high latitudes, often in areas subject to periodic saltwater inundation or spray. Plants produce a basal rosette of oblong, slightly mealy leaves and erect scapes bearing small, pale pink to lilac flowers with a yellow eye, typical of the genus. Primula stricta is one of the northernmost-occurring primroses, adapted to the short growing seasons and cold temperatures of the high Arctic. It relies on insect pollination when conditions allow, though like many Arctic plants, it may set seed through self-fertilisation. The species is assessed as Least Concern by the IUCN, with populations spread across a vast circumpolar range. It faces long-term pressure from climate change, which is altering the phenology and hydrology of Arctic coastal habitats. It is considered an indicator species for intact high-latitude coastal ecosystems.
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。
