Habitat & Geographic Range

Bamboo bear

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate coniferous forests, and temperate broadleaf and mixed forests, among 7 distinct biome types spanning the Indomalayan and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Found in China. 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.

Bamboo bear

Iconic black-and-white bear of the mountain bamboo forests of central China, giant pandas can weigh up to 125 kg and spend up to 14 hours daily consuming bamboo, which comprises 99% of their diet despite belonging to the order Carnivora. Solitary and elusive, they have a pseudo-thumb for gripping bamboo stems. Downgraded from Endangered to Vulnerable in 2016 following successful conservation and breeding programs.

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.
