Habitat & Geographic Range

Bambusbär

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.

Gemeine Rollassel

Habitat

Typically found in marine, freshwater, and terrestrial environments.

Range

Widely distributed across Africa (South Africa), Asia (Japan), Europe (6 countries), and North America (United States). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Bambusbär

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.

Gemeine Rollassel

<em>Armadillidium vulgare</em>, the common pill woodlouse, is a terrestrial isopod crustacean in the family Armadillidiidae, widely recognised for its ability to roll into a tight sphere when disturbed, a defensive behaviour that gives it the common name "pill bug" or "roly-poly." Unlike most crustaceans, it is fully adapted to life on land, breathing through modified gill-like structures that must remain moist. The species inhabits a broad range of environments, typically occurring under rocks, leaf litter, decaying wood, and in gardens and agricultural land, where it feeds on decomposing organic matter, playing an important role in nutrient cycling. <em>Armadillidium vulgare</em> is distributed across Europe, parts of Asia including Japan, South Africa, and North America including the United States, reflecting its success as a cosmopolitan species often transported inadvertently by human activity. It is assessed as Near Threatened on the IUCN Red List. Biological traits such as average lifespan, precise body dimensions, and detailed dietary composition across its range remain poorly documented in the scientific literature. Females brood their young in a marsupium, and the species is capable of parthenogenesis under certain conditions, contributing to reproductive flexibility.
