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.

Long-tailed Sylph

One of the most strikingly ornamented hummingbirds, male long-tailed sylphs have iridescent green plumage and dramatically elongated, ribbon-like outer tail feathers reaching up to 22 cm — over three times the body length. Found in Andean cloud forests of Colombia and Venezuela, they inhabit humid montane forest between 1,400–2,800 meters elevation. Males perform elaborate display flights to attract females. Their extravagant tails are a classic example of sexual selection via female preference.
