Leonhard Stejneger
Leonhard Hess Stejneger (30 October 1851 – 28 February 1943) was a Norwegian-born American ornithologist, herpetologist and zoologist. Stejneger specialized in vertebrate natural history studies. He gained his greatest reputation with reptiles and amphibians. Wetmore, Alexander (1945). "Leonhard Hess Stejneger (1851-1943)". ''Biographical Memoir. Nat. Acad. Sci.'' 24: 145-195PDF/ref> Early life and family Stejneger was born in Bergen, Norway. His father was Peter Stamer Steineger, a merchant and auditor; his mother was Ingeborg Catharine (née Hess). Leonhard was the eldest of seven children. His sister Agnes Steineger was a Norwegian artist. Until 1880, the Steineger family had been one of the wealthy families in Bergen; at that time business reverses led to the father declaring bankruptcy. Stejneger attended the Smith Theological School in Bergen from 1859 to 1860, and Bergen Latin School until 1869. His interests in zoology developed early. By age sixteen he had a print ...

Teiidae
Teiidae is a family of autarchoglossan lizards native to the Americas. Members of this family are generally known as whiptails or racerunners; however, tegus also belong to this family. Teiidae is sister to the Gymnopthalmidae, and both families comprise the Teiioidea. The Teiidae includes several parthenogenic species – a mode of clonal reproduction. Presently, the Teiidae consists of approximately 150 species in eighteen genera. Morphology and behavior Teiids can be distinguished from other lizards by the following characteristics: they have large rectangular scales that form distinct transverse rows ventrally and generally small granular scales dorsally, they have head scales that are separate from the skull bones, and the teiid teeth are solid at the base and "glued" to the jaw bones. Additionally, all teiids have a forked, snake-like tongue. They all possess well-developed limbs. Teiids are all terrestrial (few are semi-aquatic) and diurnal, and are primarily carnivor ...

San Pedro Mártir Island
San Pedro Mártir is the name of an island of Mexico, located in the Gulf of California, about halfway between the coast of Baja California and Sonora. San Pedro Mártir is located in the center of the Gulf of California and is the most remote island in the Sea of Cortez. It is located 51 km from Baja California and 53 km off the coast of Sonora. The island is 2 km long and 1.5 km maximum width, with a total of 2,729 km2 of total area (272 hectares). The island is uninhabited by humans and is 60 km from Bahía Kino, the nearest city in the state of Sonora on the west coast. The island and its marine life are, since 2002, part of the San Pedro Martir Biosphere Reserve, and is regarded as a natural laboratory of adaptive evolution, similar to that of the Galápagos Islands. It is home to 292 species of fauna and flora (both land-based and aquatic), with 42 species protected by Mexican law, and 30 listed on the Red List of Threatened Species. San Pedr ...

Aspidoscelis
''Aspidoscelis'' is a genus of whiptail lizards in the family Teiidae. Taxonomy The nomenclature for the genus ''Aspidoscelis'' was published by T.W. Reeder et al. in 2002. Many species that were formerly included in the genus '' Cnemidophorus'' are now considered ''Aspidoscelis'' based upon divergent characters between the two groups. Etymology The name ''Aspidoscelis'' literally means "shield-leg", from the Ancient Greek ' ("shield") and ' ("leg"). Species The following species are recognized as being valid. *''Aspidoscelis angusticeps'' - Yucatán whiptail *''Aspidoscelis arizonae'' - Arizona striped whiptail *''Aspidoscelis burti'' - canyon spotted whiptail *''Aspidoscelis calidipes'' - Tepalcatepec Valley whiptail *''Aspidoscelis carmenensis'' - Carmen Island whiptail *''Aspidoscelis ceralbensis'' - Cerralvo Island whiptail *''Aspidoscelis communis'' - Colima giant whiptail *''Aspidoscelis costatus'' - Mexico whiptail lizard *''Aspidoscelis cozumela'' - Cozumel ra ...

Reptiles Described In 1891
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 31 ...

Taxa Named By Leonhard Stejneger
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
