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

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

<em>Comatricha suksdorfii</em> is a plasmodial slime mold in the order Stemonitidales, class Myxomycetes, named in honor of botanist Wilhelm Nikolaus Suksdorf. As a member of the genus <em>Comatricha</em>, it is characterized by stalked, cylindrical or ovoid sporangia supported by a persistent stalk, with an internal capillitium assisting in spore dispersal. The species inhabits decomposing woody substrates and moist forest litter, where the vegetative plasmodium feeds on bacteria and other microorganisms. Environmental or nutritional cues trigger aggregation and differentiation into fruiting bodies, from which spores are released into the air. <em>C. suksdorfii</em> participates in nutrient cycling and decomposition processes in its woodland habitat. No specific geographic range data are recorded in the current record, and no quantitative biological traits are applicable to this organism. The species has not been evaluated by the IUCN.

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.
