Populations are also found in montane and highland environments at higher elevations.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Habitat

Inhabits tropical and subtropical moist broadleaf forests and deserts and xeric shrublands within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (10 countries), Asia (4 countries), Europe (6 countries), North America (Mexico), Oceania and the Pacific (Fiji), and South America (6 countries).

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.

Vibrio cholerae is a Gram-negative, comma-shaped, highly motile aquatic bacterium and the causative agent of pandemic cholera disease in humans. It inhabits coastal estuaries, river deltas, and warm marine environments, often associated with plankton, particularly copepods. This facultatively anaerobic bacterium spreads through contaminated water and food, causing severe watery diarrhea with major public health impact.
