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.

Uromyces junci is a rust fungus that parasitizes rushes (Juncus species), causing orange-brown pustular lesions on stems and leaves of its host plants in wetland and waterside habitats. This obligate biotroph depends entirely on living host tissue to complete its life cycle. It is distributed across temperate regions of Europe and beyond, wherever suitable Juncus hosts occur in moist environments.
