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

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

<em>Comatricha meandrispora</em> is a plasmodial slime mold in the genus <em>Comatricha</em>, class Myxomycetes, order Stemonitidales. The species epithet refers to the distinctive meandering ornamentation of its spores, a morphological feature used in taxonomic identification alongside capillitial structure and sporangial dimensions. It inhabits moist, shaded environments with abundant decaying wood and plant litter, as is typical of species in this genus. During its vegetative phase, the organism forms a motile plasmodium that engulfs bacteria, fungal spores, and other microorganisms as food sources. Environmental stress triggers the transition to reproductive sporangia, from which spores are released for wind dispersal. <em>C. meandrispora</em> contributes to decomposition processes in woodland ecosystems. No quantitative biological traits are available for this species, and it has not been evaluated on the IUCN Red List.

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.
