Habitat

Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Found across Europe (5 countries) and North America (United States). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Emperor Penguin

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. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

ciliate fringewort

Ciliate fringewort (Ptilidium ciliare) is a leafy liverwort in the family Ptilidiaceae, found in boreal and montane regions of the Northern Hemisphere, including Europe, North America, and parts of northern Asia. It grows as a creeping, irregularly branched mat with leaves divided into deeply fringed lobes edged with long, hair-like cilia—the characteristic feature that gives the species its common name. Ciliate fringewort colonizes a variety of substrates including rock surfaces, boulders, tree trunks, and peaty ground in open to moderately shaded habitats such as heathland, moorland, montane grasslands, and subalpine and subarctic vegetation. It is particularly common on exposed rocks in boreal and tundra zones. The species is classified as Endangered in parts of Europe, where lowland populations have declined severely due to atmospheric nitrogen deposition, afforestation of open heathland, and the loss of traditionally managed heath and moorland habitats. Populations in montane and boreal zones remain more stable. Ciliate fringewort is sensitive to elevated nitrogen levels that promote the competitive dominance of grasses and mosses. Restoration of lowland heathland and reduction of nitrogen pollution are key measures needed to support remaining European populations. The species is better represented in Scandinavian boreal habitats and North American taiga and tundra.

Emperor Penguin

The world's largest penguin, emperor penguins stand up to 1.2 meters and weigh 45 kg, inhabiting the Antarctic continent in some of the most extreme conditions on Earth. They breed in midwinter darkness at temperatures below -60°C, with males incubating single eggs on their feet under a brood pouch for 65 days while females are at sea. Their huddling behavior — cycling individuals through the warm center of thousands-strong groups — is a masterclass in cooperative survival.
