Habitat & Geographic Range

Buckelwal

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.

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).

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

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.
