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 Yellow Wood-Sorrel

Habitat

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

Range

Widely distributed across Asia (Japan, Turkey), Europe (23 countries), and North America (Canada, United States).

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 Yellow Wood-Sorrel

<em>Oxalis dillenii</em>, the common yellow wood sorrel or slender yellow wood sorrel, is a small annual to short-lived perennial herbaceous plant in the family Oxalidaceae. It is native to eastern North America and has been introduced to many parts of Europe, Asia, and other temperate regions, where it occurs as a weed of cultivated ground, roadsides, waste places, lawns, and disturbed habitats. The plant typically grows 10–35 cm tall and produces trifoliate leaves with three notched, heart-shaped leaflets that fold downward in darkness or heat. Small bright yellow flowers with five petals are produced from spring through autumn. The cylindrical seed pods eject seeds forcibly at maturity. Biological traits such as average lifespan and body measurements remain poorly documented in consolidated scientific literature. Like other Oxalis species, <em>Oxalis dillenii</em> contains oxalic acid, giving leaves a sour taste and making them mildly toxic when consumed in large quantities. The plant provides nectar for small generalist pollinators. It has not been formally evaluated for IUCN conservation status but is considered common and widespread with no conservation concerns across its introduced and native ranges.
