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
地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
