Range

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

Zweisporiger Champignon

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.

Koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
