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 capital and largest city of t ...

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] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Colubridae
Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus ''Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus ''Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.

Isla Santa Catalina
Isla Santa Catalina, officially known as Isla Catalana, is an island in the Gulf of California east of the Baja Peninsula, Baja California Peninsula. The island is uninhabited and is part of the Loreto Municipality, Baja California Sur, Loreto Municipality. The island is located south of the Gulf of California and is located 25 km from the peninsula of Baja California. It has about 13 km long and 4 km wide maximum with total area of 39.273 square kilometers. ''Isla Catalana'', being uninhabited, is separated by the sea from the nearest town, Loreto, which lies about 60 km away. Official name The official and traditional name of the island is “Isla Catalana”. The confusion was caused by some documents of cartographic service of the United States, that wrote in a chart the name “Isla Santa Catalina”.In some scientific papers, authors use both names. The official Mexican name of Isla catalana, and the one that became internationally spread by error. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Reptiles Of Mexico
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Described In 1921
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 ...

Taxa Named By John Van Denburgh
In biology, a taxon (back-formation from ''Taxonomy (biology), 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 Taxonomic rank, 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 Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu.
