Habitat & Geographic Range

Closed Gentian

Habitat

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

Range

Distributed across Canada and United States.

giraffe

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 5 distinct biome types within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

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

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.

giraffe

地球上で最も背の高い動物であるキリン（Giraffa camelopardalis）は体高が5.5mに達し、体重は最大1,750kgにもなる。すべての哺乳類と同じ7個の頸椎からなる長い首は、アフリカのサバンナや疎林のアカシアの木に食物を求めて進化した。永続的な絆を持たない緩やかな群れで生活する社会的動物で、超低周波音と身振りで意思疎通する。生息地の喪失と密猟により個体数が減少している危急種である。
