Habitat & Geographic Range

Cultivated Mushroom

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Austria, Belgium, Norway, and Sweden.

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.

Cultivated Mushroom

The most widely cultivated mushroom globally, the button mushroom in its various growth stages — white button, cremini, and portobello — accounts for approximately 40% of world mushroom production. Domesticated from wild Agaricus species found in grasslands across Europe and North America, they are grown commercially in controlled environments on composted straw and manure. Rich in B vitamins, selenium, and dietary fiber, they are one of the most nutritionally versatile fungi in human cuisine.

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.
