Habitat & Geographic Range

blue whale

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 Timothy

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and tropical and subtropical grasslands and savannas within the Indomalayan biogeographic realm.

Range

Widely distributed across Asia (6 countries), Europe (9 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Argentina, Brazil, Chile).

地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

Common Timothy

<em>Phleum pratense</em>, commonly known as common timothy or timothy grass, is a perennial grass in the family Poaceae widely cultivated and naturalized throughout temperate regions of the world. Native to most of Europe and western Asia, it has been introduced to North America, South America, New Zealand, and Australia, where it is now naturalized across vast areas. Timothy grass typically grows in meadows, pastures, roadsides, and disturbed habitats, thriving in well-drained to moderately moist soils at a broad range of elevations. It forms dense tufts with erect culms reaching up to 150 centimeters in height, topped with distinctive cylindrical, spike-like panicles that ripen to a straw-yellow color in summer. The species is one of the most important forage grasses globally, extensively cultivated for hay and silage production for livestock, particularly horses and cattle. It is also a significant source of allergenic pollen and is a major cause of hay fever in many parts of the world. <em>Phleum pratense</em> is currently assessed as Least Concern by the IUCN. Its conservation status is stable given its widespread distribution, high adaptability, and continued cultivation. Biological traits such as average lifespan under natural conditions, individual weight, and detailed growth parameters remain variable and context-dependent across populations.
