Comb Notchwort

<em>Sphenolobus minutus</em>, the comb notchwort, is a small leafy liverwort in the family Anastrophyllaceae, assessed as Least Concern on the IUCN Red List. It has a broad distribution across Europe and both North and South America, indicating a widespread presence in the Northern and Southern Hemispheres. As a liverwort, <em>S. minutus</em> belongs to the division Marchantiophyta and is among the earliest-diverging land plant lineages. It inhabits moist, shaded environments on decaying wood, mineral soil, and rock surfaces in forested and montane settings. The plant forms dense mats or patches of small, deeply lobed leaves arranged on a creeping stem, with lobes that may appear notched or comb-like in texture. Liverworts reproduce both sexually via spores and vegetatively via gemmae. <em>S. minutus</em> is sensitive to habitat moisture and atmospheric conditions, making it a potential bioindicator of environmental quality.

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.
