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 Gold-Dust

Habitat

Native to North America and South America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Brazil, Colombia, and 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 Gold-Dust

<em>Chrysothrix xanthina</em>, commonly known as common gold-dust, is a crustose lichen in the family Chrysotrichaceae. The species has been documented in Brazil, Colombia, and the United States, indicating a distribution across parts of South and North America. Lichens in the genus <em>Chrysothrix</em> are characterized by their powdery, brightly colored thallus, and <em>C. xanthina</em> is typically recognized by its distinctive yellow-gold granular coating on its substrate, produced by pigments including calycin and vulpinic acid. <em>Chrysothrix xanthina</em> typically grows on the bark of trees and occasionally on rock surfaces in humid forest and woodland habitats, where it forms conspicuous yellow patches. The species is not currently evaluated for conservation status. Biological traits of this species remain poorly documented in the scientific literature. As a lichen, <em>Chrysothrix xanthina</em> represents a symbiotic association between a fungal partner (mycobiont) and one or more photosynthetic partners (algae or cyanobacteria), and contributes to nutrient cycling and substrate weathering in the ecosystems it inhabits.
