Infection of ratites with clade 2.3.4.4b HPAIV H5N1: Potential implications for zoonotic risk

Emerging Microbes and Infections
We detected H5N1 high pathogenicity avian influenza in captive Greater Rhea (Rhea americana). Viral genetic analysis revealed the mammalian associated PB2-E627 K mutation, indicating selection of mammalian-relevant mutations in ratites.

Changes in Sperm Morphology, Morphometry, and Motility from the Epididymis to the Vas Deferens in Rheas (Rhea americana, Linnaeus, 1758)

Animals, 2023
The objective was to characterize morphological, morphometric, and ultrastructural changes in rhea spermatozoa between the epididymis and the vas deferens. Sperm samples were collected from the reproductive tracts of seven adult individuals and evaluated

Plasma and fields in the wake of Rhea: 3-D hybrid simulation and comparison with Cassini data [PDF]

Annales Geophysicae, 2008
Rhea's magnetospheric interaction is simulated using a three-dimensional, hybrid plasma simulation code, where ions are treated as particles and electrons as a massless, charge-neutralizing fluid.
