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.

Christmasbush

Habitat

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

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.

Christmasbush

Christmasbush (Chromolaena odorata) is a fast-growing perennial shrub in the family Asteraceae, native to tropical and subtropical regions of the Americas. Outside its native range, it is one of the world's most problematic invasive plant species, having established across large areas of Africa, Asia, and the Pacific. It produces abundant small, pale lavender to white flower heads in dense clusters and is well adapted to disturbed habitats, roadsides, forest margins, and abandoned agricultural land. The species grows rapidly following disturbance, forming dense thickets that exclude native vegetation and can dramatically alter local plant communities. Chromolaena odorata is fire-adapted and can increase fire intensity in invaded ecosystems, disrupting native fire regimes. It is a significant agricultural weed, colonizing plantations and reducing productivity. The plant has allelopathic properties, releasing chemical compounds that inhibit the germination and growth of neighboring plants. Despite its invasive status in many regions, Chromolaena odorata has some documented traditional medicinal uses in parts of Africa and Asia, though these do not offset its negative ecological impacts. Control of the species typically involves a combination of mechanical removal, herbicide application, and biological control agents.
