Urosaurus
''Urosaurus'' is a genus of lizards, commonly known as tree lizards or brush lizards, belonging to the New World family Phrynosomatidae. Description Species in the genus ''Urosaurus'' can be distinguished from members of the genus '' Sceloporus'' by the presence of a gular (under neck) fold and granular lateral scales. They can be distinguished from members of the genus '' Uta'' by the presence of enlarged (sometimes only slightly) dorsal scales. It is important to note that these lizards come from a different family than lizards like the common side-blotched lizard which comes from the family 'Uta'. Reproduction ''Urosaurus'' have been used as a model system in lizard life-history studies, and populations produce two or more clutches of eggs per year. Field studies have also shown a cost of reproduction in a natural New Mexico population of the species ''Urosaurus ornatus''. Species In the genus ''Urosaurus'' there are 8 species which are recognized as being valid. *'' Uro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urosaurus Ornatus
''Urosaurus ornatus'', commonly known as the ornate tree lizard, is a species of lizard in the family Phrynosomatidae. The species is native to the southwestern United States and northwestern Mexico. The species, which was formerly called simply the "tree lizard", has been used to study physiological changes during the fight-or-flight response as related to stress and aggressive competition. Its life history and costs of reproduction have been documented in field populations in New Mexico and Arizona. This species has been fairly well studied because of its interesting variation in throat color in males (within a population) that can correlate with different reproductive strategies,Hews DK, Thompson CW, Moore IT, Moore MC (1997).

Urosaurus Graciosus
The western long-tailed brush lizard (''Urosaurus graciosus'') is a species of lizard in the family Phrynosomatidae. The species is native to the southwestern United States and adjacent northern Mexico. Habitat and geographic range ''U. graciosus'' occurs in the Mojave Desert and the northwestern Sonoran Desert in the U.S. states of California, Arizona and Nevada, and in the Mexican states of Baja California and Sonora. Common name This species received its common name, long-tailed brush lizard, due to its tail, which is more than twice the body length, and due to its almost always being encountered on a tree or shrub. Behavior The long-tailed brush lizard's gray or tan coloration keeps it well camouflaged against branches while it waits for insects. Unlike most other phrynosomatid lizards, which bury in the sand at night during warm weather, ''U. graciosus'' spends the night on the tips of branches. Identification ''U. graciosus'' is distinguishable from its close relative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urosaurus Nigricauda
''Urosaurus nigricauda'' is a species of lizard. Common names for this species include the Baja California brush lizard, black-tailed brush lizard, and small-scaled tree lizard. Its range includes southern California, Baja California Baja California (; 'Lower California'), officially the Free and Sovereign State of Baja California ( es, Estado Libre y Soberano de Baja California), is a state in Mexico. It is the northernmost and westernmost of the 32 federal entities of Mex ..., and nearby Pacific islands. Taxonomy Until 1999, the small-scaled lizard, ''Urosaurus microscutata'', was considered a discrete species. ''U. microscutata'' has since been identified as the same species, and a synonym of ''U. nigricauda''.

Phrynosomatidae
The Phrynosomatidae are a diverse family of lizards, sometimes classified as a subfamily (Phrynosomatinae), found from Panama to the extreme south of Canada. Many members of the group are adapted to life in hot, sandy deserts, although the spiny lizards prefer rocky deserts or even relatively moist forest edges, and the short-horned lizard lives in prairie or sagebrush environments. The group includes both egg-laying and viviparous species, with the latter being more common in species living at high elevations. The earliest fossil remains of this group are known from the Late Cretaceous of Mongolia and belong to the genus ''Desertiguana''. As phrynosomatids are presently known only from North America, these remains indicate that phrynosomatids likely had a wider distribution in prehistoric times. Genera The Phrynosomatidae are organised into 9 genera in this family. The earless taxa (''Cophosaurus'' and ''Holbrookia'') are sister genera. Family Phrynosomatidae * ''Callisaurus' ...

Karl Patterson Schmidt
Karl Patterson Schmidt (June 19, 1890 – September 26, 1957) was an American herpetologist. Family Schmidt was the son of George W. Schmidt and Margaret Patterson Schmidt. George W. Schmidt was a German professor, who, at the time of Karl Schmidt's birth, was teaching in Lake Forest, Illinois. His family left the city in 1907 and settled in Wisconsin. They worked on a farm near Stanley, Wisconsin, where his mother and his younger brother died in a fire on August 7, 1935. The brother, Franklin J. W. Schmidt, had been prominent in the then-new field of wildlife management. Karl Schmidt married Margaret Wightman in 1919, and they had two sons, John and Robert. Education In 1913, Schmidt entered Cornell University to study biology and geology. In 1915, he discovered his preference for herpetology during a four-month training course at the Perdee Oil Company in Louisiana. In 1916, he received the degree of Bachelor of Arts and made his first geological expedition to Santo Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

Charles S
Charles is a masculine given name predominantly found in English language, English and French language, French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic, Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was ''Churl, Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinisation of names, Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as ''Carolus (other), Carolus''. Some Germanic languages, for example Dutch language, Dutch and German language, German, have retained the word in two separate senses.
