Fuscopannaria mediterranea is a small foliose to squamulose lichen forming dark brownish-grey lobes on bark, mosses, and soil in Mediterranean and sub-Mediterranean habitats. It is found across southern Europe and associated regions, particularly in humid woodland and macchia ecosystems. Near Threatened, it faces pressure from habitat degradation, overgrazing, and changes in land use in its southern European range.

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.
