Eimeria gazella Musaev, 1970 is redescribed for the first time from the feces of 3 of 6 Arabian gazelles, Gazella gazella arabica from the Riyadh Zoo in Saudi Arabia. Oocyst measurements were similar to those reported previously from the goitered gazelle, Gazella subgutturosa, in Kazakhstan (USSR). Except for our observation of many small polar granules, and Stieda body, oocyst morphology was identical to the original description of E. gazella.

Despite the diverse nature of obesity, there is compelling genetic, clinical, and experimental evidence that endorses the important contribution of brain circuits to this condition. The hypothalamus contains major regulatory circuits for bodyweight homoeostasis, the deregulation of which can lead to obesity. Although functional perturbation of hypothalamic pathways could lie at the basis of common forms of obesity, the term hypothalamic obesity has been created to define those rare forms of severe obesity where a clear hypothalamic substrate can be identified, either of genetic or acquired origin.

The replacement of grasses by shrubs or bare ground (xerification) is a primary form of landscape change in drylands globally with consequences for ecosystem services. The potential for wild herbivores to trigger or reinforce shrubland states may be underappreciated, however, and comparative analyses across herbivore taxa are sparse. We sought to clarify the relative effects of domestic cattle, native rodents, native lagomorphs, and exotic African oryx (Oryx gazella) on a Chihuahuan Desert grassland undergoing shrub encroachment.
