Habitat & Geographic Range

African elephant

Habitat

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

Range

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

Common Onion

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Widely distributed across Africa (8 countries), Asia (4 countries), Europe (23 countries), North America (United States), Oceania and the Pacific (Australia), and South America (5 countries).

African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

Common Onion

<em>Allium cepa</em> is a biennial or perennial bulbous herb in the family Amaryllidaceae, cultivated globally as one of the most widely used culinary vegetables. Its exact wild origin remains debated, though it is thought to originate from Central Asia. Today, the species is grown across Africa, Asia, Europe, North America, South America, and Oceania, adapting to diverse agricultural climates and soil types. Common onion typically grows in grasslands, agricultural fields, wetlands, and cultivated habitats. The plant forms underground bulbs that store nutrients and are harvested for food. It produces distinctive hollow, cylindrical leaves and globular flower heads. Onion is valued for its sulfur-containing compounds, which contribute to its characteristic pungent aroma and flavor, as well as its antimicrobial and antioxidant properties. Its conservation status has not been formally evaluated by the IUCN due to its extensive cultivation and absence of wild population concern. Biological traits including average lifespan, length, weight, and dietary ecology remain poorly documented in standardized wildlife databases appropriate for a cultivated crop species. <em>Allium cepa</em> is among the most economically significant vegetables worldwide, grown in over 175 countries.
