Ensifer arboris is a Gram-negative, nitrogen-fixing bacterium forming effective root nodules on leguminous trees in arid and semi-arid regions of Africa and Asia. It inhabits the rhizosphere and root nodules of Prosopis and other acacia-like leguminous trees in tropical and subtropical environments. This bacterium converts atmospheric nitrogen into biologically available ammonia for its host trees.

Scarlet Macaw

One of the most brilliantly colored birds in the Americas, scarlet macaws display vivid red, yellow, and blue plumage with wingspans reaching 1 meter. Found in humid lowland forests from Mexico to Bolivia, they are highly intelligent, long-lived — up to 75 years — and form lifelong pair bonds. They travel long distances to clay licks where they consume mineral-rich soil to detoxify seeds. Listed as Least Concern but locally threatened by habitat loss and the pet trade.
