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.

Microcalicium ahlneri is a tiny, pin-head lichen with a pale grey thallus and minute stalked apothecia characteristic of the calicioid fungi. It grows on the bark of old deciduous trees in undisturbed temperate forests of Europe. This lichen needs old-growth forest conditions and is sensitive to bark microhabitat changes from air pollution or forest management.
