  Tortoise - Wikipedia, the free encyclopedia
Tortoise is the name given to the land-dwelling reptiles most of whose body is shielded by a special shell.
The giant tortoises of the Galápagos Islands helped Charles Darwin formulate his theory of evolution, since the isolated populations on the different islands, although descended from a common ancestor, had diverged to different forms.
Turtles and tortoises are the only surviving branch of the even more ancient clade Anapsida, which includes groups such as the procolophonoids, millerettids and pareiasaurs.

 CHAPTER 5
Tortoises must have suitable soils and terrain for constructing a burrow and must have adequate annual and perennial plants in the spring and/or summer for forage.
Tortoises are measured with calipers, instruments consisting of a pair of movable curved legs fastened together at one end.
Adult male tortoises have a longer and up-curved gular horn, a concave plastron (a dish-shaped depression on the underside of the shell near the tail), a longer tail, and chin glands or knobs on the chin.

The tortoise was a male and was frequently observed on the western portion of the Natural Area in the 1970's.
Male tortoises develop chin glands or knobs on the chin, a longer gular horn, have a longer tail, and have a concave plastron (a dish-shaped depression on the posterior, underside of the shell).

These tortoises were a major source of meat for sailors in the 17th and 18th cent.
The tortoises are now protected by law, and scientists from the Charles Darwin Research Station have bred some 2,000 and set free the different subspecies on the islands from which they came.
Tortoises are extremely long-lived; there are authenticated cases of individuals living over 150 years.

These tortoises are part of a study by Curtis Bjurlin of Utah State University who is conducting research on tortoise reproductive ecology at the Marine Corps Air Ground Combat Center near Twentynine Palms, California as part of his Master's degree.

Therefore, the tortoise is able to turn around at any point within the burrow, and consequently, burrow width is a good indicator of the size (and approximate age) of the tortoise.
Tortoises living on proposed development sites are sometimes moved (or "relocated") to another area; however, this can result in the spread of disease and may disrupt resident tortoise populations.
Tortoises used in the races were removed from their natural habitats and if released, were rarely returned to their original location.

 THE DESERT TORTOISE (Gopherus agassizii)
Given the ling evolutionary history of tortoises in North America and the dynamic environment of the last thirty million years, it is indeed remarkable that the form of the four living North American tortoises have changed so little from their ancestors.
Tortoises may be distinguished from other turtle families by the following characteristics: the hindlegs are cylindrical and elephantine in shape: the feet are short, broad and club-shaped.
The desert tortoise occurs in a number of plant communities ranging from sparse creosote bush desertscrub in the winter rainfall Mohave Desert to palo verde-saguaro desertscrub in the bi-seasonal Sonoran Desert and eventually to summer rainfall tropical thornscrub and deciduous forest in Sonora and Sinaloa.

 Desert Tortoise Natural History
Tortoises may be distinguished from other turtle families by the following characteristics: the hind legs are cylindrical and elephantine in shape: the feet are short, broad and club-shaped.
The desert tortoise lives in a variety of plant communities ranging from sparse creosotebush desertscrub in the winter rainfall Mohave Desert to paloverde-saguaro desertscrub in the bi-seasonal Sonoran Desert and eventually to summer rainfall tropical thornscrub and deciduous forest in Sonora and Sinaloa.
Unfortunately, release of captive tortoises is not biologically acceptable because of the high potential risk to existing wild populations from disease introduction, disruption of population structure, and mixing of genetic stock from different regions.

 CTTC - What's In a Name? Gopherus by Mary Cohen & Michael J. Connor
However, when the Texas and desert tortoises were first described in the nineteenth century they had been given the genus name Xerobates (from the Greek xero meaning "dry" and bates meaning "one who walks or haunts").
In his description of the new tortoise Agassiz refers to Berlandier as "...a zealous French naturalist, to whom we are indebted for much of what we know of the natural history of northern Mexico".
Commonly known as the Bolson tortoise this giant Mexican gopher tortoise was described by John Marshall Legler as recently as 1959.

 Texas tortoise and cattle can co-exist
Most tortoises live in dry areas that are ideal for rangeland, and livestock grazing has been implicated in the decline of tortoises in Argentina, southern Morocco and the Turkmen Republic.
Kazmaier and his colleagues studied the effects of moderate grazing on the Texas tortoise, which lives primarily on privately-owned rangelands in southern Texas and northeastern Mexico.
Second, they caution that their work should not be applied to the desert tortoise, in part because the Texas tortoise evolved in presence of large grazers such as bison but the desert tortoise did not.
