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] |

Fernandina Island
Fernandina Island () is the youngest and third largest island in the Galápagos, as well as the furthest west. It has an area of and a height of , with a summit caldera about wide. It is younger than Isabela, being only less than one million years old since its formation. Like the other islands, it was formed by the Galápagos hotspot. The island is an active shield volcano that has most recently erupted in March 2024. Names Fernandina is named in honor of King FerdinandII of Aragon, one of the sponsors of Christopher Columbus's voyages. It was formerly known in Spanish as Isla de Plata ("Silver Island") and in English as Narbrough or Narborough Island, honoring Admiral John Narborough who commanded a British Navy squadron in the West Indies. The name was bestowed by the English pirate William Ambrosia Cowley in 1684 and preserved for centuries thereafter.

Neomammillaria Slevinii
''Mammillaria'' is one of the largest genera in the cactus family (Cactaceae), with currently 200 known species and varieties recognized. Most of the mammillarias are native to Mexico, while some come from the Southwestern United States, the Caribbean, Colombia, Guatemala, Honduras and Venezuela. The common name "pincushion cactus" refers to this genus and the closely-related ''Escobaria''. The first species was described by Carl Linnaeus as ''Cactus mammillaris'' in 1753, deriving its name from the Latin ''mammilla'', "nipple", referring to the tubercles that are among the distinctive features of the genus. Numerous species are commonly known as globe cactus, nipple cactus, birthday cake cactus, fishhook cactus or pincushion cactus (though such terms are also commonly used for related taxa, such as ''Escobaria'' or ''Ferocactus''). Description The distinctive feature of the genus is the possession of an areole split into two clearly separated parts, one occurring at the apex of ...

Sauromalus Slevini
''Sauromalus slevini'', also known as the Monserrat chuckwalla or Slevin's chuckwalla, is a species of chuckwalla belonging to the family Iguanidae. ''S. slevini'' is native to three small islands in the Sea of Cortés. Taxonomy and etymology The generic name, ''Sauromalus'', is said to be a combination of two ancient Greek words: ''sauros'' meaning "lizard" and ''omalus'' meaning "flat". The proper ancient Greek word for "flat" is however ''homalos'' (ὁμαλός) or ''homalēs'' (ὁμαλής). Its specific name, ''slevini'', is a latinized form of the surname of American zoologist Joseph Richard Slevin (1881–1957), who was Curator of Herpetology at the California Academy of Sciences from 1928 to 1957. The species was first described by American herpetologist John Van Denburgh in 1922. Van Denburgh, John (1922). "The Reptiles of Western North America. Volume I. Lizards" and "Volume II. Snakes and Turtles". ''Occasional Papers of the California Academy of Sciences' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Author Citation (zoology)
In zoological nomenclature, author citation is the process in which a person is credited with the creation of the scientific name of a previously unnamed taxon. When citing the author of the scientific name, one must fulfill the formal requirements listed under the International Code of Zoological Nomenclature ("the Code"). According to Article 51.1 of the Code, "The name of the author does not form part of the name of a taxon and its citation is optional, although customary and often advisable." However, recommendation 51A suggests, "The original author and date of a name should be cited at least once in each work dealing with the taxon denoted by that name. This is especially important and has a unique character between homonyms and in identifying species-group names which are not in their native combinations." For the sake of information retrieval, the author citation and year appended to the scientific name, e.g. genus-species-author-year, genus-author-year, family-author-year ...

Taxon
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 st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
