Habitat & Geographic Range

藍鯨

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 (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Field Horsetail

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate coniferous forests, among 5 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Mauritius), Asia (Iran, Taiwan), Europe (9 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia, New Zealand), and South America (Brazil).

藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

Common Field Horsetail

The Common Field Horsetail (<em>Equisetum arvense</em>) is a vascular plant belonging to the genus Equisetum within the family Equisetaceae. It is one of the most widespread and recognisable of the horsetail species, characterised by its jointed, hollow stems and whorls of slender branches. The species is found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate coniferous forests, spanning the Afrotropic and Palearctic biogeographic realms. Its geographic distribution is exceptionally broad, encompassing Africa including Mauritius, Asia including Iran and Taiwan, nine European countries, North America including Canada, Mexico, and the United States, Oceania including Australia and New Zealand, and South America including Brazil. <em>Equisetum arvense</em> is assessed as Least Concern on the IUCN Red List. The plant often colonises disturbed soils and is considered a persistent weed in agricultural settings. Biological traits beyond its distinctive morphology remain poorly documented in the scientific literature.
