, also called auodads, originated in the hills of the Sahara and have inhabited all the major mountains of North Africa. In the late 1800s, Barbary sheep were introduced into Europe, including Germany and Italy. Around 1900, the first Barbary sheep were transferred to the United States to be placed in zoos. Surplus zoo stock was sold to private parties who eventually released some to the wild in New Mexico in 1950 and in Texas in 1957. This has allowed a wild population to develop in the southwestern United States (Gray & Simpson, 1980).
is endemic to the mountains of Northern Africa. It has also survived in the mountains and canyons of the dry southwestern United States. live in the desert mountains from sea level up to the edge of the snows.
are also well adapted to a dry climate. They are able to survive long periods of time without fresh water intake by using metabolic water (Gray & Simpson, 1980; The Mammals of Texas - Online Edition, 1994; Schaller, 1977).
During estrus, females lick the sides of the prospective mate. The animals may touch muzzles. The male mounts the female and achieves copulation. Males defend groups of females from other males. ("The Mammals of Texas - Online Edition", 1994; Gray and Simpson, 20 November 1980)
Breeding usually occurs from September through November, but the timing can vary. Gestation lasts about 160 days, so most lambs are born between March and May. However, births have been seen as late as November. Most births produce a single offspring, but twins are born one out of every six or seven births. ("The Mammals of Texas - Online Edition", 1994; Gray and Simpson, 20 November 1980)
The timing of sexual maturity varies among males. Sperm were found in one male at eleven months; however, this is probably not the norm. Females are considered sexually mature at 19 months; however, females as young as 8 months of age have produced offspring.

In the United States, (Gray and Simpson, 20 November 1980)are commercially bred to be used for sport hunting. Nomads of the Sahara depend on for meat, hide, hair, sinews, and horns (Gray & Simpson, 1980).
It is currently unknown as to whether the ("The Mammals of Texas - Online Edition", 1994)will become a pest like many other introduced species. It has been suggested that would compete directly with mule deer for food. They might also affect the attempt at reintroduction of bighorn sheep. These two species may not survive in the same environment because of direct competition for food and other resources. have been found feeding on winter wheat crops in Texas (Mammals of Texas - Online Edition, 1994).
Commercially grown and wild populations of (Gray and Simpson, 20 November 1980)are legally hunted in New Mexico and Texas (Gray & Simpson, 1980).
A viable female offspring was produced when a female domestic goat was mated with a male Barbary sheep. This was confirmed by a backcross with a male Barbary sheep (Gray & Simpson, 1980; The Mammals of Texas - Online Edition, 1994).

living in the northern part of the Old World. In otherwords, Europe and Asia and northern Africa.
having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.
uses smells or other chemicals to communicate
in deserts low (less than 30 cm per year) and unpredictable rainfall results in landscapes dominated by plants and animals adapted to aridity. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.
ranking system or pecking order among members of a long-term social group, where dominance status affects access to resources or mates
animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.

A substance that provides both nutrients and energy to a living thing.
An animal that eats mainly plants or parts of plants.
fertilization takes place within the female's body
referring to animal species that have been transported to and established populations in regions outside of their natural range, usually through human action.

having more than one female as a mate at one time
breeding is confined to a particular season
reproduction that includes combining the genetic contribution of two individuals, a male and a female
one of the sexes (usually males) has special physical structures used in courting the other sex or fighting the same sex. For example: antlers, elongated tails, special spurs.

A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. See also Tropical savanna and grassland biome.
A terrestrial biome found in temperate latitudes (>23.5° N or S latitude). Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Fire and grazing are important in the long-term maintenance of grasslands.
