Koala

Habitat

Typically found in grasslands, forests, and vegetated habitats.

Range

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

Adlafia brockmannii is a small pennate diatom found in freshwater benthic habitats, typically attached to substrates in streams and lakes. Its distinctive asymmetric valve outline and raphe structure help distinguish it within the genus Adlafia. This diatom is used in paleolimnological and water quality studies as its presence or absence can reflect historical changes in water chemistry.

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.
