Coastal Dendrobium

Dendrobium litorale, the coastal dendrobium, is an epiphytic orchid in the family Orchidaceae native to lowland coastal forests and mangrove margins across the Pacific island region, including Papua New Guinea, the Solomon Islands, and adjacent island groups. The genus Dendrobium is one of the largest in the Orchidaceae, comprising over 1,800 described species distributed from tropical Asia through Australasia and the Pacific, and includes numerous horticulturally important species cultivated worldwide. Dendrobium litorale grows as an epiphyte attached to tree branches and trunks in humid coastal forest environments, including forest-mangrove transition zones subject to salt spray and tidal influence that few other orchids can tolerate. The pseudobulbs store water and nutrients, enabling survival during intermittent dry periods. Flowers are typically small to medium-sized with white or pale coloring and complex labellum structures that guide pollinators, often specific bee species, into contact with pollen. The species is classified as Least Concern by the IUCN. Coastal lowland forests across the Pacific face significant ongoing pressure from logging, oil palm conversion, and human settlement expansion, threatening the specific forest-mangrove habitats this coastal orchid requires.

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.
