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.

Hemitrichia pardina is a myxomycete (slime mould) producing small, stalked, globose to ovoid sporangia with a yellowish to brownish peridium, growing on decaying wood and plant litter in forest habitats. Its internal capillitium threads assist in spore dispersal. This species is widely distributed across temperate and tropical forests and contributes to microbial food webs.

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.
