Gopher Tortoises
''Gopherus'' is a genus of fossorial tortoises commonly referred to as gopher tortoises. The gopher tortoise is grouped with land tortoises that originated 60 million years ago, in North America. A genetic study has shown that their closest relatives are in the Asian genus ''Manouria''. The gopher tortoises live in the southern United States from California's Mojave Desert across to Florida, and in parts of northern Mexico. Gopher tortoises are so named because of some species' habit of digging large, deep burrows (gophers are small terrestrial burrowing rodents). Most notably, ''Gopherus polyphemus'' digs burrows which can be up to in length and in depth. These burrows are used by a variety of other species, including mammals, other reptiles, amphibians, and birds. Gopher tortoises are in length, depending on the species. All six species are found in xeric habitats. Numerous extinct species are known, the oldest dating to the Priabonian stage of the Late Eocene of the United ...

Gopherus Polyphemus
The gopher tortoise (''Gopherus polyphemus'') is a species of tortoise in the family Testudinidae. The species is native to the southeastern United States. The gopher tortoise is seen as a keystone species because it digs burrows that provide shelter for at least 360 other animal species. ''G. polyphemus'' is threatened by predation and habitat destruction. The gopher tortoise is a representative of the genus ''Gopherus'', which contains the only tortoises native to North America. The gopher tortoise is the state reptile of Georgia and the state tortoise of Florida. Etymology The specific name, ''polyphemus'', refers to the cave-dwelling giant, Polyphemus, of Greek mythology. Gopher tortoises are so named because of some species' habit of digging large, deep burrows like the gopher. Description The gopher tortoise is a fairly large terrestrial reptile which possesses forefeet well adapted for burrowing, and elephantine hind feet. These features are common to most tortoises ...

James Graham Cooper
James Graham Cooper (June 19, 1830 – July 19, 1902) was an American surgeon and naturalist. Cooper was born in New York. He worked for the California Geological Survey (1860–1874) with Josiah Dwight Whitney, William Henry Brewer and Henry Nicholas Bolander. He was primarily a zoologist, but he also made significant botanical collections from San Diego to Fort Mohave, Arizona in 1861. Cooper was active in the California Academy of Sciences, eventually becoming Director of the Museum. He obtained his medical degree in 1851 and practiced in New York City until 1853. Spencer F. Baird, the Assistant Secretary of the Smithsonian Institution at that time, helped Cooper work with the Pacific railroad survey parties working in the Washington Territory. He joined this survey under Captain George McClellan as a surgeon until 1854. In 1855 he visited San Francisco and the Panama Isthmus. He collected many birds during this expedition. In 1860, he returned west and joined the Blake Expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonoran Desert
The Sonoran Desert ( es, Desierto de Sonora) is a desert in North America and ecoregion that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the southwestern United States (in Arizona and California). It is the hottest desert in both Mexico and the United States. It has an area of . In phytogeography, the Sonoran Desert is within the Sonoran Floristic province of the Madrean Region of southwestern North America, part of the Holarctic realm of the northern Western Hemisphere. The desert contains a variety of unique endemic plants and animals, notably, the saguaro (''Carnegiea gigantea'') and organ pipe cactus (''Stenocereus thurberi''). The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin, Mojave, and Chihuahuan deserts) because it provides subtropical warmth in winter and two seasons of rainfall (in contrast, for example, to the Mojave's dry summers and cold winters). This creates an ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gopherus Morafkai
The Sonoran Desert tortoise (''Gopherus morafkai''), or Morafka's desert tortoise, is a species of tortoise native to the Sonoran Desert. Taxon history In 2011, on the basis of DNA, geographic, and behavioral differences between desert tortoises east and west of the Colorado River, it was decided that two species of desert tortoises exist: Agassiz's desert tortoise (''Gopherus agassizii'') and Morafka's desert tortoise (''Gopherus morafkai'').Genetic Analysis Splits Desert Tortoise into Two Species US Geological Survey (2011-06-28).

Chihuahuan Desert
The Chihuahuan Desert ( es, Desierto de Chihuahua, ) is a desert ecoregion designation covering parts of northern Mexico and the southwestern United States. It occupies much of far West Texas, the middle to lower Rio Grande Valley and the lower Pecos Valley in New Mexico, and a portion of southeastern Arizona, as well as the central and northern portions of the Mexican Plateau. It is bordered on the west by the Sonoran Desert, the Colorado Plateau, and the extensive Sierra Madre Occidental range, along with northwestern lowlands of the Sierra Madre Oriental range. Its largest, continual expanse is located in Mexico, covering a large portion of the state of Chihuahua, along with portions of Coahuila, north-eastern Durango, the extreme northern part of Zacatecas, and small western portions of Nuevo León. With an area of about , it is the largest desert in North America. The desert is fairly young, existing for only 8000 years. Geography There are several larger mountain ranges ...

Gopherus Flavomarginatus
The Bolson tortoise (''Gopherus flavomarginatus''), also called the Mexican giant tortoise or yellow-margined tortoise, is a species of tortoise from North America. Of the six North American tortoise species, it is the largest, having a carapace length of about . It lives in a region of the Chihuahuan Desert known as the Bolsón de Mapimí, which is located in north-central Mexico. Discovery The Bolson tortoise was discovered only in 1959. The legend is that a group of biologists working in the Bolsón de Mapimí were at a ranch and saw chickens eating out of a large tortoise shell. They inquired about the origin of the shell and the locals responded by saying that it was, "la tortuga grande del desierto", the big turtle of the desert. In 1979 the 340,000 hectare Mapimi Biosphere Reserve was created to protect the Bolson tortoise and other unique flora and fauna of the Bolsón de Mapimí. Despite this designation, cattle ranching and mining still occur in the reserve. Whether t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gopherus Evgoodei
The Goode's thornscrub tortoise or Sinaloan thornscrub tortoise or Sinaloan desert tortoise or Goode's desert tortoise (''Gopherus evgoodei'') is a species of tortoise that is native to the Sinaloan desert region. First described in 2016, ''G. evgoodei'' inhabits Tropical Deciduous Forest and Sinaloan Desertscrub biomes in Mexico. Its range may overlap in the north with ''G. morafkai'', the Morafka's or Sonoran desert tortoise. Goode's thornscrub tortoise is named for Eric V. Goode, a conservationist, naturalist, and founder of the Turtle Conservancy Taxon history Bogert and Oliver were the first researchers to notice a distinct morphology in the southern range of what was then considered ''G. agassizii,'' but could not confirm a new species due to limitations of small sample size Edwards et al. sampled 233 tortoises that represented Sonoran and Sinaloan lineages of ''G. morafkai.'' The authors then conducted a large-scale genetic analysis that when combined with significant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tamaulipan Mezquital
The Tamaulipan mezquital ( es, Mezquital Tamaulipeco) is a deserts and xeric shrublands ecoregion in the southern United States and northeastern Mexico. It covers an area of , encompassing a portion of the Gulf Coastal Plain in southern Texas, northern Tamaulipas, northeastern Coahuila, and part of Nuevo León. Distribution The Sierra Madre Oriental range to the west separates the Tamaulipan mezquital from the drier Chihuahuan Desert. The Tamaulipan matorral is a transitional ecoregion between the mezquital and the Sierra Madre Oriental pine-oak forests to the west and the Veracruz moist forests to the south. The Western Gulf coastal grasslands, known as the Tamaulipan pastizal south of the border, fringe the Gulf of Mexico. The Edwards Plateau savannas lie to the north, and the East Central Texas forests and Texas blackland prairies to the northeast. Geography The Bordas Escarpment transects this ecoregion, running from near the southern limit northwest to the vicinity of ...
