Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Privet

The Common Privet, <em>Ligustrum vulgare</em>, is a semi-evergreen to deciduous shrub in the family Oleaceae, native to central and southern Europe but now naturalized globally across Africa, Asia, and the Americas. It typically grows in hedgerows, woodland margins, scrublands, and disturbed habitats, tolerating a wide range of soil types and light conditions from full sun to partial shade. <em>Ligustrum vulgare</em> is characterized by opposite, lance-shaped to oval dark green leaves, dense clusters of small white flowers with a strong fragrance produced in early summer, and glossy black berries that persist through autumn and winter. The berries are toxic to humans and many mammals but are consumed by birds, which serve as primary seed dispersers and contribute to the species' spread across its introduced range. The plant is widely used in horticulture as a hedging and topiary plant due to its dense, fast-growing form and tolerance of clipping. In some regions outside its native range, it is considered invasive. Common Privet is assessed as Least Concern on the IUCN Red List. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.

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。
