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 Toadskin Lichen

Habitat

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

Range

Distributed across Norway 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 Toadskin Lichen

<em>Lasallia papulosa</em>, known as the common toadskin lichen, is a foliose lichen in the family Umbilicariaceae, belonging to the broader group of rock-dwelling umbilicate lichens. This species typically grows attached to exposed siliceous rock surfaces, particularly granite, quartzite, and other acidic rock outcrops in montane, boreal, and arctic environments across North America and parts of Europe and Asia. The thallus is typically olive-brown to dark gray in color, with a distinctively blistered or pustulate upper surface texture that gives the species its common name. It attaches to the substrate by a single central holdfast (the umbilicus), allowing the irregular, lobed thallus edges to lift freely. <em>Lasallia papulosa</em> is ecologically important as a pioneer species on bare rock, contributing to weathering processes and providing microhabitat and food for specialized invertebrates. It is sensitive to air pollution, particularly sulfur dioxide, and is often used as a bioindicator of air quality. The geographic range spans rocky regions of eastern North America, Scandinavia, the Alps, and parts of northern Asia. The species is currently assessed as Least Concern by the IUCN. Biological traits such as average growth rates, thallus dimensions, and biomass estimates remain poorly documented in the scientific literature.
