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 Rim 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 Rim Lichen

<em>Lecanora pulicaris</em>, the common rim lichen, is a crustose lichen in the family Lecanoraceae, order Lecanorales, within the kingdom Fungi (as the mycobiont component). It is distributed across temperate and boreal zones, with documented records from Denmark, Norway, Portugal, Sweden, and the United States. The species is assessed as Least Concern on the IUCN Red List, reflecting its widespread occurrence on bark of deciduous and coniferous trees across the Northern Hemisphere. Rim lichens in the genus Lecanora are characterized by their apothecia — disc-shaped reproductive structures rimmed by a thallus margin — which give the genus its common name. <em>Lecanora pulicaris</em> typically forms pale gray-green crustose patches on smooth to moderately rough bark surfaces, particularly favoring the bark of birch, alder, and other hardwood trees in well-lit forest and woodland environments. As a lichen, it is a symbiotic organism comprising a fungal partner (mycobiont) and photosynthetic algal or cyanobacterial partners (photobionts), deriving nutrients through photosynthesis and mineral absorption from the substrate. Biological traits such as lifespan and growth rates remain poorly documented for this taxon, though crustose lichens typically grow very slowly. It serves as a bioindicator of air quality in temperate forests.
