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 Earthball

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), North America (United States), and South America (Brazil, Chile).

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 Earthball

<em>Scleroderma citrinum</em>, commonly known as the common earthball or pigskin poison puffball, is a widespread ectomycorrhizal fungus in the family Sclerodermataceae, classified as Least Concern by the IUCN. The species occurs across Asia, Europe, North America, and South America, typically found on forest floors, decomposing wood, and mineral-rich acidic soils in association with hardwood and conifer tree roots. Unlike true puffballs, <em>Scleroderma citrinum</em> is considered poisonous and should not be confused with edible species. Its thick, warty outer skin ranges from yellowish-brown to ochre and encloses a dark purplish-black spore mass that matures over time. The species plays an important ecological role as a mycorrhizal partner, forming mutualistic associations with the roots of oaks, beeches, pines, and other trees, facilitating the uptake of water and nutrients by host plants in exchange for photosynthetically derived carbon. Fruiting bodies typically emerge from late summer through autumn, releasing spores through irregular cracks or a central apical opening when mature. <em>Scleroderma citrinum</em> is a host for the parasitic fungus <em>Pseudoboletus parasiticus</em>, making it ecologically significant within forest fungal communities. Biological traits of this species remain poorly documented in the scientific literature.
