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 Orange Lichen

Habitat

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

Range

Distributed across Denmark, Norway, Portugal, Sweden, 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 Orange Lichen

<em>Xanthoria parietina</em> is a foliose lichen in the family Teloschistaceae, one of the most conspicuous and widely recognized lichens across Europe and North America. It is recorded in Denmark, Norway, Portugal, Sweden, and the United States. The species typically colonizes bark, rock surfaces, walls, roof tiles, and other exposed substrates in nutrient-enriched environments. Its vivid orange to yellow-orange thallus is produced by the pigment parietin, which functions as a photoprotective compound shielding the lichen from UV radiation. <em>Xanthoria parietina</em> is considered a nitrophilous species, thriving in habitats enriched by nitrogen compounds, such as those near bird roosting sites, agricultural areas, and urban zones. It is highly tolerant of air pollution and is frequently used as a bioindicator in ecological studies. The IUCN lists this species as Least Concern given its broad distribution and tolerance of disturbed environments. As a lichen, it is a mutualistic association between a fungal partner and algal or cyanobacterial photobionts. Biological traits such as growth rates, lifespan, and dietary ecology remain poorly documented in standardized databases for lichen species.
