The dry, arid climate and terrain of the South Western USA are much closer to that of the steppes of Arabia than the wetter climate and more lush pastures of, say, the mid-Atlantic region or the plains of the Midwest. I have observed that these drier conditions are resulting in Arabian horses that look much closer to the horses raised in Syria and Arabia, and to those raised in Namibia and the drier parts of South Africa. Drier skin, stronger, more solid bone, more visible tendons, and something different in the way the eyes shine that I cannot describe. This observation is a central tenet of the writings of French master breeder Robert Mauvy, based on his empirical observations. I would like to read any scientific papers on the climate and terrain impact on horse phenotypes, if anyone knows of any. The mare below, Roxana Star (Personic LF x Jauhar Al Khala by Sportin Life), a Kuhaylah Hayfiyah of Davenport bloodlines born in 2005, illustrates this observation. She is in the Southwestern USA, with Christine Emmert. Photos by Christine.
