Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.

Sphingopyxis panaciterrulae is a Gram-negative aerobic rod isolated from ginseng-cultivated soils in Korea. It inhabits the rhizosphere of Panax ginseng plants and associated agricultural soils. This chemoheterotroph decomposes organic matter in ginseng farming soils and may participate in ginsenoside transformation.
