Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Polar bear

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Chopard's Cave-cricket

Chopard's Cave Cricket (Dolichopoda chopardi) is a camel cricket or cave cricket in the family Rhaphidophoridae, found in cave systems and subterranean environments of the western Mediterranean region, including areas of southern France, northern Italy, and possibly adjacent territories. Cave crickets of the genus Dolichopoda are obligate or near-obligate cave dwellers (troglobionts or troglophiles), characterised by their extreme leg elongation — particularly the hind legs and antennae, which are several times longer than the body — reduced eyes or eyelessness, lack of wings, and depigmented or pale yellowish-brown body colouration. These adaptations reflect evolutionary response to permanent cave darkness. Dolichopoda cave crickets feed as omnivores on organic detritus, bat guano, fungi, and invertebrates carried into cave systems by water or wind. They are sensitive bio-indicators of cave ecosystem health. The species is named in honour of Lucien Chopard, a French entomologist. The IUCN classifies this species as Data Deficient, reflecting limited survey data on its distribution and population status across cave systems within its range. Cave-dwelling invertebrates face threats from groundwater pollution, cave tourism impacts, changes in cave hydrology, and the spread of white-nose syndrome affecting bat populations whose guano provides food resources.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
