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.

Tulostoma fimbriatum is a stalked puffball (stiltball) fungus with a small, round spore sac elevated on a slender stalk, growing in dry, sandy or calcareous soils in open habitats including dunes, short grasslands, and steppes across Europe and beyond. It releases spores through an apical mouth (peristome). Classified as Endangered, this distinctive species is threatened by loss of short, open grassland habitats and sand stabilisation.
