Arthur Loveridge
Arthur Loveridge (28 May 1891 – 16 February 1980) was a British people, British biologist and Herpetology, herpetologist who wrote about animals of East Africa, particularly Tanzania, and of New Guinea. He gave Binomial nomenclature, scientific names to several gecko species in those regions. Life Arthur Loveridge was born in Penarth, Wales, and was interested in natural history from childhood. He gained experience with the National Museum Cardiff, National Museum of Wales and Manchester Museum before becoming the curator of the Nairobi Museum (now the National Museums of Kenya, National Museum of Kenya) in 1914. During World War I, WW1, he joined the King's African Rifles#First World War, East African Mounted Rifles, later returning to the museum to build up the collections. He then became an assistant game warden in Tanganyika (territory), Tanganyika. In 1924, he joined the Museum of Comparative Zoology in the grounds of Harvard University in Cambridge, Massachusetts, where ...

Reptiles Described In 1941
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 ...

Carl Gans
Carl Gans (7 September 1923 – 30 November 2009) was a German-born American zoologist and herpetologist. He and Glen Northcutt proposed the provocative theory of "new head theory", opened up evolutionary developmental biology as a new discipline. Early life and education Gans, who was Jewish, was born in Germany. While a teenager in 1939, he was able to escape Nazi Germany by fleeing to the United States, where he completed his education. He attended George Washington High School in New York City. In 1944 he earned a BS in Mechanical Engineering at New York University, and in 1950 an MS in Mechanical Engineering at Columbia University. In 1957 he received a PhD in Biology from Harvard University."Carl Gans, Obituary". ''The New York Times''. Legacy.com. Career From 1947 to 1955 Gans worked as an engineer. From 1957 to 1958 he was a Fellow in Biology at the University of Florida. From 1958 to 1971 he taught biology at the State University of New York, Buffalo. From then ...

Oviparity
Oviparous animals are animals that reproduce by depositing fertilized zygotes outside the body (i.e., by laying or spawning) in metabolically independent incubation organs known as eggs, which nurture the embryo into moving offsprings known as hatchlings with little or no embryonic development within the mother. This is the reproductive method used by most animal species, as opposed to viviparous animals that develop the embryos internally and metabolically dependent on the maternal circulation, until the mother gives birth to live juveniles. Ovoviviparity is a special form of oviparity where the eggs are retained inside the mother (but still metabolically independent), and are carried internally until they hatch and eventually emerge outside as well-developed juveniles similar to viviparous animals. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or f ...

Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilia Crocodilia () is an order of semiaquatic, predatory reptiles that are known as crocodilians. They first appeared during the Late Cretaceous and are the closest living relatives of birds. Crocodilians are a type of crocodylomorph pseudosuchia ...ns (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantag ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Dorsum (anatomy)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

William Roy Branch
William Roy "Bill" Branch (12 May 1946, London, England – 14 October 2018, Port Elizabeth, South Africa) was a British-South-African herpetologist. Branch studied at the University of Southampton where he remained until completing his Ph.D. degree (''Studies on a foetal-specific alpha-globulin FPin the rabbit'' ). From 1972 he worked as a scientist in the Life Sciences Division of the Atomic Energy Board in Pretoria doing research on, inter alia, liver cancer, but returned to the University of Southampton in 1976 to take up a post-doctoral research fellowship in the Department of Biology studying the synthesis of chemicals in the liver of foetal rabbits. He started working at Port Elizabeth Museum in 1979 and retired in 2011, when he was appointed as Research Associate and Curator Emeritus. Over a period of almost 40 years he conducted field work in about 20 African countries and played a major role in building up the large reptile and amphibian collections at the Museum. Publ ...

Pedro De Grys
Pedro is a masculine given name. Pedro is the Spanish, Portuguese, and Galician name for ''Peter''. Its French equivalent is Pierre while its English and Germanic form is Peter. The counterpart patronymic surname of the name Pedro, meaning "son of Peter" (compared with the English surname Peterson) is Pérez in Spanish, Peres in Galician and Portuguese, Pires also in Portuguese, and Peiris in coastal area of Sri Lanka (where it originated from the Portuguese version), with all ultimately meaning "son of Pero". The name Pedro is derived via the Latin word "petra", from the Greek word "η πέτρα" meaning "stone, rock". The name Peter itself is a translation of the Aramaic ''Kephas'' or '' Cephas'' meaning "stone". An alternative archaic variant is Pero. Notable people with the name Pedro include: Monarchs, mononymously *Pedro I of Portugal *Pedro II of Portugal *Pedro III of Portugal *Pedro IV of Portugal, also Pedro I of Brazil *Pedro V of Portugal *Pedro II of Braz ...
