Habitat & Geographic Range

大翅鯨

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Closed Gentian

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Distributed across Canada and United States.

大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

Closed Gentian

The closed gentian or bottle gentian (Gentiana andrewsii) is a striking herbaceous perennial in the family Gentianaceae native to eastern and central North America, found from Quebec and New England west to Nebraska and south to Georgia. Unlike most gentians, the deep violet-blue flowers of this species remain permanently closed — the petals fused into a bottle-like shape through which only strong bumblebees, primarily Bombus species, can force entry to access nectar and pollen, making it a specialist of bumblebee pollination. Plants grow 30–60 cm tall in moist prairies, wet meadows, fens, stream banks, and open woodland edges, flowering in late summer and autumn when few other wildflowers are in bloom. The closed flower form prevents small insects from accessing floral rewards while selecting for robust, strong-flying pollinators capable of forcing the petals apart. Closed gentian is declining across its range due to loss of moist prairie and fen habitats, wetland drainage, invasive species competition, and the regional decline of specialist bumblebee pollinators, with which its reproductive success is closely linked.
