John Van Denburgh
John Van Denburgh (August 23, 1872 – October 24, 1924) was an American herpetologist from California (who also used the name Van Denburgh in publications, hence this name is used below). Biography Van Denburgh was born in San Francisco and enrolled at Stanford University in 1891. As of 1895, he organized the herpetology department of the California Academy of Sciences. In 1897, he received a Ph.D. from Stanford University and earned a M.D. from Johns Hopkins in 1902. Subsequently, he practiced medicine in San Francisco, while again serving as curator of the herpetological collections of the California Academy of Sciences. After the San Francisco earthquake of 1906 he was instrumental in rebuilding the lost herpetology collections through new expeditions and also acquisitions of other collections. In 1922, he published the two-volume ''The Reptiles of Western North America''. He died in 1924 while on vacation in Honolulu Honolulu ( ; ) is the List of capitals in the Un ...

Joseph Richard Slevin
Joseph Richard Slevin (September 13, 1881 – February 17, 1957) was an American herpetologist and the second curator of herpetology at the California Academy of Sciences, with which he was affiliated for over 50 years. He collected reptile and amphibian specimens from around the world, notably in the Galápagos Islands in a 17-month expedition, and was largely responsible for re-growing the academy's herpetological collection following its destruction in the 1906 San Francisco earthquake. He wrote or co-wrote nearly 60 scientific papers, and is commemorated in the scientific names of over a dozen species or subspecies of animals and plants. Early life Slevin was born in San Francisco, California, and attended St. Ignatius High School. His father, Thomas E. Slevin, was an amateur ornithologist and member of the California Academy of Sciences. Joseph studied classical languages at Saint Mary's College in Kansas, then enlisted in the United States Navy. By 1904 he had served his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teiidae
Teiidae is a family of lacertoidean 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 Gymnophthalmidae, Gymnopthalmidae, and both families comprise the Teiioidea. The Teiidae includes several Parthenogenesis, parthenogenic species – a mode of clonal reproduction. Presently, the Teiidae consists of approximately 150 species in eighteen genus, genera. Morphology and behavior Teiids can be distinguished from other lizards by the following characteristics: large rectangular scale (zoology), scales that form distinct transverse rows Anatomical terms of location#Dorsal and ventral, ventrally and generally small granular scale (zoology), scales Dorsum (anatomy), dorsally, head scales that are separate from the skull bones, and teeth that are solid at the base and "glued" to the jaw bones. Additionally, all teiids have a forked, snake-like tongue. They all possess we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques Cousteau Island
Isla Cerralvo (), as is commonly named, whose official name is Isla Jacques Cousteau (; ), is an island located off the Cerralvo Canal coast near La Paz, Baja California Sur, Mexico. It is long with a land area of , and is the ninth-largest island in Mexico. The island is adjacent to the towns of El Sargento and La Ventana and is part of Municipality of La Paz. The island peak comes to and the ridge line runs north–south with many small streams draining east to Gulf of California and west to Cupalo Canal. There are many steep bluffs on the eastern sides and many sandy beaches and points on the west side. There is abundant marine life surrounding this island which are due to underwater topography and ocean currents and are the traditional fishing grounds of the local ejidos and is dotted with temporary fish camps. Virtually all local marine life must migrate past the island, and water visibility goes up to 30 meters, making it a prime location for big game fishing. There are ...

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'' – western Mexico whiptail lizard *''Aspidos ...

Reptiles Described In 1921
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and Amniotic egg, amniotic development. Living traditional reptiles comprise four Order (biology), orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting Taxonomy, taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the Class (biology), class Reptilia ( ), which corresponds to common usage. Modern Cladistics, cladistic taxonomy regards that group as Paraphyly, paraphyletic, since Genetics, genetic and Paleontology, paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among re ...

Taxa Named By John Van Denburgh
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
